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......
黑色岩系样品中铂族元素的分析方法王君玉1,毋喆1,胡家贞1,李志伟1(1.河南省郑州市河南省岩石矿物测试中心河南省金属矿产成矿地质过程与资源利用重点实验室)摘 要:近年来发现,不同地质时代的黑色岩系都可能含有贵金属矿物,但其分析测试结果的重现性很差,即"若有若无",严重影响地质研究工作的进展.根据黑色岩系样品的成分特征,对常规测定铂族元素的锍试金配方做了改进,增加了具有还原性的覆盖剂,且无需加入Os同位素稀释剂.通过实验选择了合适比例的试金配料,熔融后获得的镍扣直接用水浸泡粉化后加入盐酸分解,然后用贴有滤膜的普......

noble metals deposited on the carbon surface, the platinum is frequently used as a valuable and efficient catalyst [9]. Ageeva et al [9] studied the mechanism and kinetics of the sorption process of platinum, palladium and gold complexes on the BAU activated carbon (AC). The effects of pH and initial concentration of precious metals on the adsorption equilibrium of those metals were investigated......

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......
