The Discussion of the Tungsten Determination with the Sulfocyanate Luminosity in the Copper Mine
Under the existence of sulfocyanate in the acidic property mediu, by the reduction to the yellow complex, the wave -length is the most intelligent in 404nm and the content of the tungsten at 0~1.50% scopes which conforms to the Beer′s law has a good selectivity.The method is applicable to the determination of the low personal status tungsten in the mineral stone.
