摘要
本文研究了利用薄层树脂相通过光度法测定痕量铋的新方法 .铋 (Ⅲ )在硫酸介质中与碘化钾形成稳定的橙黄色络合物 ,将其富集在H+型 (73 2 #)阳离子交换树脂上 ,将着色的树脂制成薄层直接测定 .本法操作简便 ,装皿容易 ,有较好的选择性 。
A new anaytical method for direct thin layer phase spectrophotometric determination of trace bismuth has been developed. A orange complexes was obtained by the reaction between Bi(Ⅲ) ion and KI in sulphuric acid medium and the enriched on cationic exchange resin (732 #).The concentration of bismuth was directly determined on a thin layer of the bismuth enriched cationic etehange resin. The proposed method is rapid,sensitive and selective.It has been used to determine bismuth in water and satisfactory results were obtained.
