摘　　要：以琼脂(Agar)为包裹剂,采用流变相法制备琼脂包裹纳米零价铁(Agar-Fe0),并用XRD、SEM和TEM、氮气吸附-脱附手段对样品进行表征。考察了Agar-Fe0投加量、Cu(II)浓度、pH对模拟废水中铜的去除效果的影响。结果表明:在Cu(II)废水浓度为10 mg/L,p H=8,Agar-Fe0投加量为0.3 g/L去除效果最好,去除率达99.87%。The wrapped nanoscale zero-valent iron （Agar-Fe^0） is synthesized by using rheological phase reaction method with agar as coating agent. The sample is characterized by means of XRD, SEM, TEM and N2 adsorption-stripping. The effect of Agar-Fe^0 dosage, initial Cu（II） concentration and pH values on removal rate of Cu（II） in simulated wastewater are studied. The experimental results indicate that the best removal rate of Cu（II） is 99.87% when the initial Cu（II） concentration is 10 mg/L, the pH value is 8, the Agar-Fe^0 dosage is 0.3 g/L.
