摘要
报道了应用KDS 1型快速控制电位电解仪测定银合金中银的快速方法 ,采用在氨性介质中 ,加入EDTA作掩蔽剂 ,阴极电位控制在 0 .2 0～ 0 .30V(vs.SCE)进行电解。该方法可用于含银wAg≥ 0 .2 %的多种合金 。
A rapid method for the determination of silver in silver alloys by controlled cathode potential electrogravimetry is reported in this paper. The electrolysis is carried out in an ammoniacal solution using EDTA as masking agent. The cathodic potential is controlled at 0.20～0.30V( vs .SCE) during the electrolysis by using the KDS 1 rapid controlled potential electrolysis apparatus. The proposed method can be used in the analysis of many kinds of silver bearing alloy having silver content ( w %)≥0.2%. The analytical results obtained proved to have a better accuracy and precision than those by the conventional AgCl gravimetric method.
