Efficient analytical separation and an estimation of the microgram quantities of silver present in various alloys and minerals have been made possible by the Weisz ring-oven technique in combination with the nonsophisticated nondestructive technique of electrographic sampling. Silver is fixed selectively with IH-benzotriazole after masking interfering ions with EDTA or tartarate, and then it is estimated using FTC as a chromogenic spray reagent because the chelate of silver ions with 1,2,3-benzotriazole is white.
