REMOVAL OF HEAVY METALS USING NANOSCALE ZERO-VALENT IRON IMMOBILIZED BY SODIUM ALGINATE/β-CYCLODEXTRIN

Kang Haiyan Yang Zhiguang Huang Xiaonan,

摘要: 针对纳米Fe0在空气中易被氧化的问题,应用海藻酸钠、β-环糊精对纳米Fe0进行协同固定化,考察了原料配比、交联剂浓度等对凝胶球性能的影响,并对固定化纳米Fe0材料的稳定性进行了考察。实验结果表明:以1.5%SA、0.5%β-CD为原料,4.0%Ca Cl2为交联剂制备的固定化纳米Fe0具有较高的反应活性;固定化Fe0对Pb2+的去除效率明显高于Cd2+,反应4 h,200 mg/L的Pb2+去除率可达99.3%,主要通过凝胶球与Fe0联合作用去除。该材料保存120 d后仍具有较高的反应活性。

Abstract: To avoid the oxidation of nano-Fe0 in the air，nanoparticles were immobilized in sodium alginate /β-cyclodextrin gelbeads． The effects of the ratio of raw materials and cross-linker concentration et al． on gel-beads properties were investigated． Optimal reactivity was received with the nano-Fe0 immobilized by 1. 5% SA，0. 5% β-CD and with 4. 0% CaCl2 as the crosslinker． Much higher removal efficiency was obtained in Pb2 + removal compared with Cd2 + ． Pb2 + ( 200 mg /L) with 99. 3% removal ratio was obtained after 4 h． Pb2 + was removed by gel-beads combined with Fe0 ． High reactivity was still achieved after 120 days with the immobilized nano-Fe0 ．
