DIN 38413-4:1986 German standard methods for the examination of water, waste water and sludge; individual constituents (group P); determination of carbon disulfide (P 4)
The standard describes a chemical method for the determination of carbondisulfide in water and waste water with concentrations between 0,1 and 10 mg/l. The water sample is to add with phosphoric acid. By passing-in of nitrogen the sulphides get free. The carbondisulfide is to catch by an adsorber and the extinction to measure with a photometer at 302 m.#,,#
