Sl.No. Synosis Points
1 This standard (Part 32) prescribes the following methods for the determination of chloride in water and wastewater: a) Argentometric Method (applicable in the range of 0.15 mg to 10 mg of chloride); b) Mercuric nitrate method; c) Potentiometric method; d) Automated ferricyanide method; and e) Dissolved anions by liquid chromatography of ions (The lower limit of application is >= 0,1 mg/l for chloride. The lower limit of application depends on the matrix and the interferences encountered.; f) Liquid chromatographic separation using low-capacity anion exchanger (working range 0.1 mg/l to 50 mg/l); and g) Photometric detection .
2 This standard prescribes four methods for the determination of chloride. The argentometric method is suitable for use in relatively clear waters when 0.15 to 10 mg of chloride is present in the portion titrated. The end point of mercuric nitrate method is easier to detect. Potentiometric method is suitable for coloured or turbid samples. The ferricyanide method is an automated technique. In case of any difference of opinion, the argentometric method shall be the referee method.
