摘要
本文研究了微波气相热压法新技术分解高纯铂在密闭的聚四氟乙烯高压罐中，以微波瞬间加热混合酸产生的高压、纯净蒸气分解金属铂，此法避免了酸中杂质的沾污以制备供高纯铂分析的试液。
A new technique of microwave gas phase heating pressure was used to dissolve high pure platinum sample. In a tightly closed PTFE high pressure vessel the platinum was dissolved by the elevating pressure and pure acid vapor produced by heating the mixed acids instantly. By this method, the contamination of impurities in the acids can be avoided and the solution thus prepared may be provided for the analysis of high pure platinum with guarantee of the precision of trace impurities determination and decrease of the testing limit. This method may also be used to prepare pure platinum compounds and their salts.
