摘　　要：以绿茶提取液作为还原剂和稳定剂绿色合成纳米铁,并用天然高分子材料海藻酸钙将其包覆获得新材料,海藻酸钙包覆绿色合成纳米铁(CA-Fe),并用于降解孔雀绿。本文研究了不同反应条件,如不同材料、孔雀绿的初始浓度、反应温度对CA-Fe降解孔雀绿的影响。CA-Fe对孔雀绿的降解符合伪一级动力学。5次循环利用后,CA-Fe对水溶液中孔雀绿的去除效率仍维持在81.5%。最后提出CA-Fe对孔雀绿的可能降解机制。Green tea extract was used as the reducing and stabilizing agent for green synthetic iron nanoparticles,and it was coated with natural polymer material calcium alginate to obtain a new material of calcium alginate coated green synthetic iron nanoparticles(CA-Fe)for the degradation of malachite green.In this paper,the effects of different reaction conditions,such as various materials,initial concentration of malachite green,and reaction temperature on the degradation of malachite green using CA-Fe were investigated.The degradation of malachite green by CA-Fe was in accordance with the pseudo primary kinetics.The removal efficiency of malachite green from aqueous solution by CA-Fe was maintained at 81.5%after 5 cycles of recycling.Finally,a possible degradation mechanism of malachite green by CA-Fe was proposed.
