The complex is weighed as AgC3H5N4S after drying at 120-30 . Separation of silver from a large number of cations is described. Application of the method for quantitative analysis of alloys and complexes of silver is reported. The average relative error for the range 20-70 mg of silver is 0.25% and the relative standard deviation at the 40-mg level is 0.2%. 1978.4-Amino-3-methyl-5-mercapto-1,2,4-triazole as a gravimetric reagent for determination of silver in silver compounds, alloys and complexesArticle
