碘量法及ICP-AES法补正测定粗碲中的铜量试验研究
The Experiment Study on Amendment Determination of Copper Volume in Crude Tellurium by Iodimetry and ICP-AES Methods
摘要
Abstract
The copper volume in crude tellurium is determined by both iodimetry and ICP-AES method that correction of the residual volume of filtrate, the following items are investigated, including impurites content, acid decomposition test, the selection of precipitant separation method, the dosage of buffer solution in the titration process, the effect of co-existing ion on determination, the results show: the proper acid decomposition method is selected, and each parameters are optimized, the relative standard deviation (RSD) of determining results is in the range of 0.15%~0.71%, the recovery rate with standard is in 99.70%~100.26%, which has good precision, high accuracy, the method is simple and rapid.关键词
