KMUTT Annual Research

KMUTT Annual Research Abstracts 2005 The pressure drop for the case with the addition of baffles increased as well, however. The improvement of mixing effectiveness was found to depend strongly on the operating conditions and geometric configurations. IJ-051 EFFECTS OF DIETHYLENE GLYCOL ON TIO 2 THIN FILM PROPERTIES PREPARED BY SOL-GEL PROCESS Puangrat Kajitvichyanukul, Parichart Amornchat Science and Technology of Advanced Materials Journal, Vol. 6, No. 3-4, April-May 2005, pp. 344-347 A technological approach for the sol-gel processing of stabilized thin film titanium dioxide on the stainless steel has been extensively investigated in this paper. Diethylene glycol was used as a drying control additive agent. The transformation of a titanium dioxide thin film was studied by X-ray diffraction. The surface morphology was observed by scanning electron microscope (SEM). As results, this substance helped in stabilizing the solution and improving the adhesive property of the film. Without diethylene glycol, the thin film peeled off. Substantially improvement of film was seen with the high amount of diethylene glycol applied. This effect was confirmed by adhesive test and the morphology of stainless steel surface. In addition, adding diethylene glycol to the sol–gel solution exerted less effect on transformation of anatase to rutile phase in titanium dioxide structure. Thus, the nanocrystalline anatase phase of thin film TiO 2 can be controlled and the high photoactivity of the film is secure. IJ-052 PHOTOCATALYTIC REMOVAL OF ZINC (II) IN UV- IRRADIATED TITANIA SUSPENSIONS Puangrat Kajitvichyanukul, Thanakorn Sungkaratana Asian Journal in Energy and Environment, Vol. 6, No. 2, 2005, pp. 111-124 The photocatalytic reduction of zinc(II) in aqueous suspensions of TiO 2 on UV illumination was investigated. Synthetic wastewater containing zinc with an initial concentration of 160 mg/L was used in this study. The zinc removal efficiency is reported 19 respectively as a function of solution pH, mass of TiO 2 , hole scavenger species and reactor types. It was found that direct photoreduction removed very little zinc (II) due to its negative reduction potential compared to the conduction band edge potential of TiO 2 , The studied hole scavengers (formate and acetate ions) played a major role in reducing zinc(II) from synthetic wastewater. The best condition found to decrease the zinc(II) concentration to lower than the standard level (5 mg/l) was at pH 1.6 with a TiO 2 loading of 20 g/l and 1 M of formate ions. This system successfully removed zinc in the quartz reactor within 5 hours reaction time. Results from this study may be beneficial to zinc(II) removal from industrial wastewater. IJ-053 ROLE OF pH, ORGANIC AND INORGANIC IONS ON PHOTOCATALYTIC REDUCTION OF CHROMIUM(VI) USING TIO 2 AND ULTRAVIOLET LIGHT Puangrat Kajitvichyanukul, Apichon Vatcharenwong ASEAN Journal on Science and Technology for Development, Vol. 22, No. 1&2, 2005, pp. 169- 179 Chromium(VI) is a metal which is widely used in many industrial processes especially in electroplating and tanning industries. It is a toxic pollutant whose use and discharge are restricted due to its known hazardous nature. Titanium dioxide-based photocatalysis, a widely used and simple method, can be considered as one of potentially viable techniques for the removal of this ion from water. In this paper we describe role of pH, organic and inorganic ions on enhancing the photocatalytic reduction of Cr(VI). During the dark adsorption, pH is the important key factor for interfacial adsorption of metals on titanium dioxide surface. It is found that Cr(VI) is well adsorbed in acidic pH. For the photocatalysis process, the direct reduction of Cr(VI) after prolonged UV-irradiation is also very favourable in acidic pH especially at pH 3. In the presence of acetate ions, Cr(VI) removal is improved in the neutral and basic solutions. Formate ions are also shown to exert a dramatic accelerating influence on Cr(VI) reduction in media of all pH values. For inorganic anions, nitrate ions exhibited the positive effect on enhancing the Cr(VI) removal in neutral media while International Journal

20 phosphate ions prohibited the photocatalytic reduction process. The tentative schemes of the reaction mechanism for these enhancements are also given. IJ-054 SOL-GEL PREPARATION AND PROPERTIES STUDY OF TIO 2 THIN FILM FOR PHOTOREDUCTION OF CHROMIUM(VI) IN PHOTOCATALYSIS PROCESS Puangrat Kajitvichyanukul, Jirapat Ananpattarachai, Siriwan Pongpom Science and Technology of Advanced Materials Journal, Vol. 6, No. 3-4, April-May 2005, pp. 352-358 In this paper, a sol–gel technique with dip coating method is used to prepare photocatalytic TiO 2 thin films immobilized on glass plates. The structure and morphology of thin films are characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The structural characterization of this film shows that the titanium oxide anatase phase is predominant at 400-700 °C. The appearance of the rutile phase depends mainly on the number of coating cycles. For example, the rutile phase appeared at 600 °C with 5 coating cycles, however, it disappeared from TiO 2 crystalline after 8 coating cycles. The obtained thin films from each preparation condition were employed in experiment of photoreduction of chromium. The results show that the Chromium(VI) is successfully removed from aqueous in photocatalysis system using the obtained thin film with high portions of anatase phase. The photoactivity of the prepared TiO 2 thin films exhibits a comparable efficiency with TiO 2 powder, Degussa P-25. IJ-055 BIODEGRADATION OF PENTACHLOROPHENOL IN A MEMBRANE BIOREACTOR Chettiyappan Visvanathan, L.N. Thu, Veeriah Jegatheesan, Jin Anotai Desalination, Vol. 183, No. 1-3, November 2005, pp. 455-464 Pentachlorophenol (PCP) is a toxic chemical, often used in the formulation of pesticide, herbicide, anti fungal agent, bactericide and wood preservative. This study is aimed at evaluating the potential of membrane KMUTT Annual Research Abstracts 2005 bioreactor (MBR) to treat PCP contaminated wastewater. Synthetic wastewater with COD of 600 mg/L was fed into the MBR at varied PCP loading rate of 12-40 mg/m 3 /d. A PCP removal rate of 99% and a COD removal rate of 95% were achieved at a hydraulic retention time of 12 hs and a mixed liquor suspended solids (MLSS) concentration of 10,000 mg/L. When sodium pentachlorophenol (NaPCP), which has higher solubility in water, was used in the second phase of the study, at loading rates varying from 20 to 200 mg/m 3 . d, the removal rate of NaPCP was higher than 99% and the removal rate of COD was more than 96%. It was also found that at higher biomass concentrations, biosorption played an important role besides the biodegradation process. Batch experiments conducted in this study revealed that the sorption capacity to be 0.63 (mg PCP/g biomass) and occurred rapidly within 60 min. This phenomenon could enhance the PCP degradation through increased contact between microorganism and PCP. Further, the membrane resistance was low (trans-membrane pressure of 14 kPa) even after more than 100 ds of operation. In addition, the toxic level of PCP in the influent could have induced the microorganisms to secrete more extra-cellular polymeric substances (EPS) for their protection, which in turn must have increased the viscosity of the mixed liquor. IJ-056 MONITORING OF PITTING CORROSION IN STAINLESS STEELS USING ACOUSTIC EMISSION Chalermkiat Jirarungsatean, Asa Prateepasen, Pakorn Kaewtrakulpong Official Journal : Australian Institute for Nondestructive Testing, Vol. 42, No. 3, May/June 2005, pp. 76-81 A correlation between AE activity and pitting corrosion was demonstrated. Two types of stainless steel generally used for storage tank were selected as the specimens in this research. To accelerate the corrosion rate, the electrochemical process was applied. The progression of the pitting corrosion was measured by SEM and optical microscopy. From the experimental results, the corrosion stage of both types of stainless steel can be divided into two groups: the breakage of the passive film and the progress of the corrosion.
