Abstract:The carboxymethyl salix psammophila powder(CMS) as carrier, the carboxymethyl salix psammophila powder supported nanoscale zero-valent iron(NZVI/CMS) was prepared by using liquid phase reduction method. The micro structures of nanoscale zero- valent iron(NZVI) and NZVI/CMS were characterized by means of SEM, FTIR, XRD and TEM. The effects of the adsorbent dosage, initial concentration of Pb2 , adsorption time, adsorption temperature and pH on adsorption properties of NZVI and NZVI/CMS for Pb2 were studied. The characterization results show that NZVI was loaded on the CMS successfully, and the NZVI were scattered obviously on CMS, reunion phenomenon had been resolved effectively, CMS played a role in dispersing NZVI particles.The adsorption results showed that the adsorption capacities of NZVI and NZVI/CMS reached a maximum of 390.30 mg?g-1 and 535.50 mg?g-1 as the dosage was 0.05 g and 0.01 g respectively, the initial concentration of Pb2 was 600 mg?L-1 and 400 mg?L-1, the adsorption time was 120min, the adsorption temperature was 30℃ and the pH of Pb2 solution was 4.5 and 4.0 respectively.
