摘要
本文建立了以金橙G(1-苯偶氮基-2-萘酚-6,8-二磺酸钠)为显色剂,在表面活性剂溴化十六烷基吡啶CPB增敏作用下测钯的新的流动注射分光光度法。方法简便、快速,具有良好的选择性。在数倍贵金属离子存在下,可不经分离直接在水相测定矿石中的钯的含量,结果令人满意。
A new method for the determination of Pd(Ⅰ)in the orange G-hexadecylpyridinium bromide (CPB) system is established by flow injection analysis. The method was selective, rapid and simple, and the detection limit was 0,8μg/ml for Pd(Ⅰ). The linear range was found to be 1.0~10.0μg/ml,and the sampling frequency was 70/h without separation, The method was applied to the determination of Pd(Ⅰ) in ores with good results.
