| 2 | REMOVAL OF PHOSPHATES FROM WATER BY PILLARED RECTORITE显示文摘The presence of trace phosphates in treated wastewater from municipalities and industries is often responsible for eutrophication problems in lakes, rivers, and other water bodies. In this paper, we report the removal of PO43- from water by using a pillared rectorite that we synthesized recently. The results show that cross-linking can significantly increase the adsorbing capacity of Na-rectorite for phosphates. The pH, the concentrations of F-, NH4+ and COD are main factors, which affect the results for pillared rectorite to adsorb phosphates from water. The OH-, and F- ions decrease the capacity to adsorb phosphates, while the COD and NH4+ ions increase it. | DU Dongyun LI Dunshun YU Zhongshan | 2005 | Chinese Journal of Reactive Polymers2005，14，1： | 0 |
