适用范围：The method consists in decomposing a test portion, reducing arsenic (V) to arsenic (III) with tin(II) chloride and transforming the arsenic into arsine by action of nascent hydrogen, forming a red coloured complex by the action of the arsine on silver diethyldithiocarbamate and measuring at a wavelength of 520 nm.
