摘　　要：根据钯离子和碘离子生成红色络合物的原理建立了测定乙烯羰基合成丙酸甲酯催化剂中钯含量的分光光度法。该方法准确、简单、快速,样品回收率为95%~103%,线性范围为0μg/mL^10.20μg/mL,相对标准偏差为0.34%。A spectrophotometric method for determination of the pdladium in the catalyst for synthesis of methyl propionate fi＇om ethylene by carbonylation was established based on the fact that Pd＋ and I- might form a red complex. The method was accurate, simple and fast. The sample recovel7 was 95%-103%; the lineal range was 0μg/mL-10.20μg/mL; and the relative standard deviation was 0.34%.
