Study on New Kind of Rare Earth-Containing Flocculants of Poly-Ferric Sulfate Chloride Zhu Hengxiang1,Li Jinai1,Pang Xijie1,Luo Yongjian1,Yao Jiye1,Xiao Xueyan1,Kuang Juchi1 (1.Department of Chemistry and Chemical Engineering , Foshan University, Foshan 528000, China) Abstract:A new kind of rare earth- containing flocculant of poly-ferric sulfate chloride (PFSCRE) was studied, and proved......
by ammonium sulfate [4,5]. Ammonium adsorption by the soils within the mining area occurs with seeping and leakage of the leaching agent. Therefore, is constantly accumulating and remains... is associated with leaking solution of ammonium sulfate, and the other form relates to the adsorption onto clay minerals. Adsorption being a complex process [11,12], it is very important to study......
Effect of Sulfate Ions on YAG Powders Synthesized by Microwave Homogeneous Precipitation Xu Hongyan1,Wang Jieqiang1,Yue Yunlong1,Wang Yong1 (1.School of Materials Science and Engineering, Jinan.... The results show that sulfate ions influence the dispersion, composition and morphology of the YAG precursors. The addition of moderate sulfate ions can produce YAG powders with nano size and excellent......
