摘要
研究了铂、钯、金、铂镀金、石墨及Ag—AgI指示电极,提出了一个用Ag～AgI指示电极(vs.SCE),碘化钾电位滴定钯的方法。该方法可应用于钯合金、氯化钯、钯催化剂中钯的测定。对于含钯60％和O.5％的物料,变异系数分别为0.5％和4％。
The indicator electrode of platinum, palladium, gold plated platinum, graphite, and Ag—AgI have been studied, a method was presented for the determination of palladium by potassium iodide potentiometric titration with Ag—Agl as indicator electrode, This method can be applied to the analysis of palladium in its alloys, palladium chloride, and catalysts. The variation coefficient was 0.5% and 4% for 60% and 0.5% palladium respectively.
