Phosphorus and inorganic phosphorus compounds. Method of arsenic determination
Фосфор и неорганические соединения фосфора. Метод определения мышьяка
Status: Effective. The limitation of the effectiveness period has been lifted: Protocol No. 3-93 of the IGU dated 03.03.93 (IUS 5-6-1993)
The standard applies to phosphorus and inorganic phosphorus compounds and establishes a method for the determination of arsenic. The method is based on the recovery of arsenic compounds to arsine, the interaction of arsine with a solution of silver diethyldithiocarbamate in pyridine and photometric measurement of the optical density of the red complex formed at a wavelength of 540 nm.
Стандарт распространяется на фосфор и неорганические соединения фосфора и устанавливает метод определения мышьяка. Метод основан на восстановлении соединений мышьяка до арсина, взаимодействии арсина с раствором диэтилдитиокарбамата серебра в пиридине и фотометрическом измерении оптической плотности образовавшегося красного комплексного соединения при длине волны 540 нм.
