Zinc in Drinking-water - WHO
www.who.intAtomic absorption spectrophotometry is the most widely used method for the determination of zinc. The detection limit of the direct air–acetylene flame method is 50 µg/litre (4). Low concentrations can be measured by chelating zinc with ammonium pyrrolidine dithiocarbamate and extracting it with methyl
