The textile industry’s increasing popularity elevates water usage and eventually causes
high expel rate of wastewater with excessive dye pollutants. Therefore in this study,
a type of anionic clay, nickel/aluminium-layered double hydroxide (NiAL), was studied
as a potential adsorbent for anionic dyes, mainly Eriochrome Black T (EBT) and Alizarin
Red S (AR). The NiAL was synthesized via co-precipitation method and was
characterized using powder X-Ray diffraction (PXRD) and Fourier Transform Infrared
spectrophotometer (FTIR). The morphology and composition of the NiAL was further
analyzed using Scanning Electron Microscope (SEM), Carbon, hydrogen, nitrogen,
sulphur elemental analyzer (CHNS) and Thermogravimetric Analyzer (TGA). NiAL was
then used as adsorbent for the removal of both dyes in aqueous solution which was
tested at different mass and its adsorption ability was analyzed.
