is drained inevitably in the production of precious metal alloy powder. Recovering precious metals from the waste water is not only beneficial to reducing cost, but also can reserve the resources... concentration of waste water,but it may become less efficient or even useless when trace precious metal is to be recovered from waste water[2, 5]. Thus in this study, a novel process was put forward to recover......

; Abstract: The adsorption properties of the four precious metal ions (Ag(Ⅰ), Au(Ⅲ), Pd(Ⅱ) and Pt(Ⅳ)) on the commercial Cl--form... were investigated. The precious metal ions adsorbed could not be eluted completely after the saturated adsorption because the precious metal ions were found to be reduced to their metallic states......
Metal Dusting-Mechanisms and Preventions () 摘要:Metal dusting attacks iron, low and high alloy steels and nickel-or cobalt-base alloys by disintegrating bulk metals and alloys into metal particles... at UNSW is aimed at determining the detailed mechanism of metal dusting of both ferritic and austenitic alloys, in particular the microprocesses of graphite deposition, nanoparticle formation......
