Effective removal of heavy metals from aqueous solutions by orange peel xanthate LIANG Sha(梁 莎)1, GUO Xue-yi(郭学益)1, FENG Ning-chuan(冯宁川)2, TIAN Qing-hua(田庆华)1 1. School... heavy metals (Cu2+, Cd2+, Pb2+, Zn2+ and Ni2+) were studied. FTIR spectra, Zeta potentials and TG analysis were used to characterize prepared orange peel xanthate. Effects of various parameters......

Platinum Precursors Effects on Pt/(Ce-Zr-La-Pr)O Catalysts张爱敏,宁平摘 要:(Ce-Zr-La-Pr)O acted as substrates and Pt acted as catalytic active component..., but that of the catalyst prepared by Pt(NH3)2(NO2)2 appeared "V" shape. It indicates that the active metals precursors and their solutions acidities had direct influences on the mutual functions of the active metals......
metals and the recovery of platinum group metals (PGMs). The complete dissolution of base metals sulfides leads to a reduction in the amount of flotation carrier for enriching PGMs, decreasing the recovery... through the flotation technology. Key words: platinum group metals; oxygen pressure leaching; flotation; recovery 1 Introduction Platinum group metals (PGMs) are widely used in manufacturing catalysts......

to be equipped with catalytic converters, the main role of which is to obtain substances harmless to the environment instead of exhausted gases. Catalytic converters contain platinum group metals (PGM) especially platinum, palladium and rhodium. The price of these metals and their increasing demand are the reasons why today it is necessary to recycle used auto catalytic converters. There are many......
