J. Cent. South Univ. Technol. (2008) 15: 656-662 DOI: 10.1007/s11771-008-0122-8 Removal of anionic ions from single material solution by bauxite tailings modified with FeCl3·6H2O LAN Ye(兰 叶)1...; Abstract: The adsorbabilities of the unmodified and modified bauxite tailings for Cr(Ⅵ), As(Ⅴ) and F(Ⅰ) ions were investigated. Batch experiments were carried out to determine......
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......
