分子-钯络合物,并研究了它们对对硝基甲苯的催化活性。
Palladium can be separated from polyxene by the process of resolving polyxene,removing nitrate,precipitating palladium,etc.The grade of pure platinum obtained from the process is more than 99.95%.
粗铂经王水溶解,赶硝,加入丁二酮肟使大部分钯以沉淀的形式与铂分离,余留的少量钯用溴酸钠水解法处理,可达到铂钯分离的目的,所得纯铂品位99.95%。
Some systems, like Fortress (Mirage Dental Co.) and Cerinate (Den-Mat Corp.), utilize a direct build up of a ceramic on a refractory die or on a master die swedged with palladium or platinum foil.
