镍基合金 (含铬、钯、锗、硅 )中钯的测定通常借助钯和镍在不同酸度下与丁二酮肟络合作用。钯在稀盐酸 ( ｐＨ3～ 5)有溶液中与丁二酮肟生成稳定的黄色络合物沉淀 ,经 10 5～ 110℃烘干称重而测定钯。该法虽可准确测定 ,但沉淀分离条件苛刻 ,分析周期长等缺点。本文利用硫脲可 The determination of palladium in nickel-based alloys (including chromium, palladium, germanium, silicon) usually complexes with dimethylglyoxime with palladium and nickel at different acidities. Palladium in dilute hydrochloric acid (pH3 ~ 5) with a solution of dimethylglyoxime to form a stable yellow complex precipitate, dried at 105 ~ 110 ℃ and weighed to measure the palladium. Although the method can be accurately measured, but the separation of harsh conditions of precipitation, analysis cycle length and other shortcomings. In this paper, thiourea can be used
