| 摘 要： | 本文提出了微波密闭消解处理难溶贵金属化合物Pt（NH3）4Cl2、Pt（NH3）2Cl2、Pt（NH3）2（NO2）2和K2PtCl4的方法；对比了它们的微波密闭消解和传统分解条件；分析了消解后Pt的含量。结果表明：上述各类化合物对应消解时间分别为传统分解法的1／15、1／13和1／11；分析手段随之简化且总分析流程大大缩短；两种方法测得的Pt含量吻合。 |

| Abstract: | A microwave-assisted sealing digestion method for determination of platinum in difficultly decomposed compounds of Pt(NH_(3))_(4)KG-*5]Cl_(2),Pt(NH_(3))_(2)Cl_(2),Pt(NH_(3))_(2)KG-*5](NO_(2))_(2) and K_(2)PtCl_(4) is proposed.The dissolved conditions of the proposed method and traditional methods are comparatively studied.The experimental results show that digestion time of the develeped method for platinum compounds is 1/15,1/13 and 1/11 times of the traditional methods,respectively.The develeped method is simple and rapid.Its accuracy is verified with traditional methods,and the analytical results are in good agreement. |
