The isolation of zinc, by selective release from its cyanide complex and subsequent determination with 2-carboxy-2'-hydroxy-5'-sulfoformazyl-benzene (zincon), has been studied, and a simplified procedure has been developed. 

A sample splitting technique is introduced to compensate for both reagent and sample blanks. The proposed method showed equal or greater tolerance to common metal interferences than the chloral hydrate system, with the exception of manganese.
