摘要
试样经盐酸-硝酸混合酸溶解,高氯酸冒烟,于盐酸体系中用丁二酮肟沉淀剂与溶液中的钯络合,形成沉淀,计算样品双二苯基膦二茂铁二氯化钯中钯的质量分数。对样品的预处理和检测方法进行了研究和对比,试验证明,本方法准确,简便、有效、准确度较高,适用于双二苯基膦二茂铁二氯化钯中钯含量的检测。
The analytic method of determining the content of palladium content by idimethylglyoxime gravimetry method in hydrochloric acid was used, with hydrochloric acid, nitric acid-perchloric acid melting bis（diphenyl- phosphino）ferrocenedichloropalladium（ Ⅱ ） in the electric heating plate. The concentration of palladium content in solution was deposited by dimethylglyoxime gravimetry in order to calculate the sample mass fraction of palladium in bis（diphenylphosphino）ferrocenedichloropalladium（ Ⅱ ）. The methods for sample pretreatment and determination were studied and contrasted. The experiment proved that the accuracy of this method, this method is convenient and rapid, especially suitable for determining the content of palladium in bis（diphenyl- phosphino）ferrocenedichloropalladium（ Ⅱ ）.
