="ChDivSummary" name="ChDivSummary">Zinc oxide,which has photocatalytic activity,is used as white pigment for cosmetics.A certain degree of sebum on the skin is decomposed by ultraviolet radiation in sunlight.In this work,zinc oxide was shaken with phosphoric acid to synthesize a white pigment for cosmetics.Zinc oxide was set with 0.1 mol/L of phosphoric acid at P/Zn=1/1 and 1/2,and then shaking......
Trans. Nonferrous Met. Soc. China 22(2012) 1209-1216 Determination of arsenic speciation in secondary zinc oxide and arsenic leachability LI Yu-hu, LIU Zhi-hong, ZHAO Zhong-wei, LI Qi-hou, LIU Zhi... in secondary zinc oxide generated from fuming furnace were investigated. The results revealed that there are mainly three types of secondary zinc oxide based on three arsenic species. The main phase......
Sulfidation roasting of lead and zinc carbonate with sulphur by temperature gradient methodZHENG Yong-xing(郑永兴), LIU Wei(刘维), QIN Wen-qing(覃文庆), JIAO Fen(焦芬), HAN Jun-wei(韩俊伟), YANG Kang(杨康), LUO Hong-lin(罗虹霖) (School of Minerals Processing and Bioengineering, Central South University, Changsha 410083, China)Abstract:In order to enhance the lead and zinc recovery from the refractory Pb-Zn oxide......
of synergistic extraction of zinc from ammonium sulfate and ammonium chloride systems with mixtures of Mextral54-100 and tri-nalkylphosphine oxide(TRPO) dissolved in n-heptane was described. Various.... The synergistic effect is explained by the formation of adduct between zinc chelates and trialkylphosphine oxide. The thermodynamic data show that the extraction reaction is exothermic and stripping......
