DIN 38413-4-1986 德国检验水、废水和污泥的标准方法.专用组分(P 组).第4部分:二硫化碳的测定(P 4)
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.#,,#
