Study on the adsorption behavior of Cd(ll) on modified sodium trititanate whisker and its application
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 Cd(Ⅱ) in a static system was investigated by inductively coupled plasma atomic emission spectrometry(FAAS).The main factors affecting adsorption and desorption of Cd(Ⅱ),the adsorptive capacity of Cd(Ⅱ) in optimal condition and adsorption isotherm and the influence of coexistent ions were examined.The adsorptive rate for Cd(Ⅱ) on 0.2500 g of modified sodium trititanate whisker at PH 5.0 was the best.Cd(Ⅱ) adsorbed on the modified sodium tretitanate whisker could be eluted with 10 mL of 2.0 mol/L HC1.The adsorptive performance of modified sodium trititanate whisker was better than that of unmodified sodium trititanate whisker.
