【摘要】基于砷、铅、锡、锑、铋与碘离子形成络合物,用MIBK萃取使其与基体分离,用石墨炉原子吸收光谱法测定了铁镍基高温合金中这五种元素。文章主要对萃取条件及萃取后剩余基体对待测元素的影响进行了研究,同时采用掩蔽的方法消除了合金中钨、铌、钽的干扰。在所选定的实验条件下,测得砷、铅、锡、锑、铋的回收率范围为93%~99%;相对标准偏差范围为8.8%~12%。更多还原

【Abstract】 A method was developed for the determination of As,Pb,Sn,Sb and Bi in high temperature iron and nickel-based(alloy) by graphite furnace atomic absorption spectrometry combined with liquid-liquid extraction.These elements formed complexes with I~-ions and were subsequently extracted into MIBK to be separated from matrix(elements.) The effects of remnant(matrix) elements were studied in detail.Meanwhile,the interferences of other elements,such as W,Nb and Ta,were eliminated with masking method.The recovery rates for As,Pb,Sn,Sb and Bi are in the range of 93%-99 %,and the relative standard deviations are from 8.8% to 12%.更多还原
