1.3.3.4 Salinity The halogen compound in seawater may be precipitated as very slightly soluble silver complexes. When all chlorides were precipitated by addition of silver nitrate, free ions from the silver were detected with a potassium chromate indicator, which changes the color. The calculations of salinity were made after correction from Knudsen’s table. Salinity is expressed in psu. 1.3.3.5. Ammonia - Nitrogen (NH4 - N) Ammonia - Nitrogen in seawater samples was determined with the indophenol blue method using trione. Care has been taken for the analysis of ammonia with ammonia free distilled water to avoid any contamination as ammonia is highly soluble in water. The absorbance measurements were made at 630 nm. NH4 - N is expressed in µg/l. 1.3.3.6. Nitrite - Nitrogen (NO 2 - N) Nitrite was determined by the method of Bendschneider and Robinson whereby the nitrite in water sample was diazotised with sulphanilamide and coupling with N-1-Naphthyl ethylene diamine dihydrochloride. The absorbance of the resultant azo dye was measured at 543 nm. NO 2 - N is expressed in µg/l. 1.3.3.7 Nitrate - Nitrogen (NO3 - N) Nitrate in seawater sample was first reduced to nitrite by heterogeneous reduction by passing the buffered samples through an amalgamated cadmium column and the resultant nitrite was determined. The measured absorbance was due to initial nitrite in the sample and nitrite obtained after reduction of nitrate. Necessary correction was therefore made for any nitrite initially present in the sample. NO 3 - N is expressed in µg/l. 17
