Sorption of uranyl ions on silica: Effects of contact time, pH, ionic strength, concentration and phosphate
作者： Zhang Hongxia , Tao Zuyi
关键词:
摘要: The sorption of UO22+ and phosphate on silica were simultaneously studied. effect contact time between the solid phase aqueous solution, pH ionic strength in absence presence was investigated. investigated too. isotherms at different values determined. It found that as compared with phosphate, is increased low decreased high pH; abruptly increasing range 3-6; gradually 2-12; insensitive sensitive to strength.
