Study on the adsorption behavior of Co(Ⅱ) on modified sodium trititanate whisker

摘要：

　　The modification of sodium trititanate whisker surface was performed by means of impregnation procedure to fabricate the modified sodium trititanate whisker,which was characterized by infrared spectroscopy(IR).Its adsorptive performance for Co(Ⅱ) in a static system was investigated by FAAS.The main factors affecting adsorption and desorption of Co(Ⅱ),the adsorptive capacity of Co(Ⅱ) in optimal condition and adsorption isotherm.The adsorptive rate for Co(Ⅱ) on 0.2500 g of modified sodium trititanate whisker at PH 6.0 was the best.Co(Ⅱ) adsorbed on the modified sodium tretitanate whisker could be eluted with 10 mL of 3.0 mol/L HC1.The adsorptive performance of modified sodium trititanate whisker was better than that of unmodified sodium trititanate whisker.
