Study on the adsorption behavior of Co(Ⅱ), Pb(Ⅱ) on modified sodium trititanate whisker and its application to wastewater
Abstract—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 scanning electron microscopy(SEM) and infrared spectroscopy(IR). Its adsorptive performance for Co(Ⅱ), Pb(Ⅱ) in a static system was investigated by inductively coupled plasma atomic emission spectrometry(ICP-AES). The main factors affecting adsorption and desorption of Co(Ⅱ), Pb(Ⅱ), the adsorptive capacity of Co(Ⅱ), Pb(Ⅱ) in optimal condition and adsorption isotherm and the influence of coexistent ions were examined. The comparative test for selectivity was done. The adsorptive rate for Co(Ⅱ) and Pb(Ⅱ) on 0.2500 g of modified sodium trititanate whisker at PH 5.0 was the best. Co(Ⅱ), Pb(Ⅱ) adsorbed on the modified sodium tretitanate whisker could be eluted with 10 mL of 3.0 mol/L HCl. The adsorptive performance of modified sodium trititanate whisker was better than that of unmodified sodium trititanate whisker. The sobent has been applied to the enrichment and separation of Co(Ⅱ), Pb(Ⅱ) in water sample to determine Co(Ⅱ), Pb(Ⅱ).
