摘　　要：研究了LS-5000型氨基磷酸型螯合树脂对Pb2+的吸附性能及在模拟浓缩果汁铅的去除中的应用。结果表明,LS-5000型氨基磷酸型螯合树脂在酸性条件下对Pb2+具有良好的吸附性能,静态吸附平衡时间为1 h,最大吸附量为5 527.45μg/g树脂,负载Pb2+的树脂可用1 mol/L的HNO3解吸,解吸后的树脂可以再利用。LS-5000氨基磷酸型螯合树脂可用于果汁、浓缩果汁中Pb2+的去除,用0.5 g树脂处理50 mL含Pb2+4.0μg/mL果汁,Pb2+的一次去除率可达99%。Studied on the LS-5000 amino phosphoric acid type chelating resin on the adsorption of Pb2＋ and its application in the removal of lead from the simulation concentration fruit juice. The results showed that the LS-5000 amino phosphoric acid type chelating resin in acidic conditions for Pb2. has a good ad-sorption performance, static adsoq0tion equilibrium time was 1 h, the maximum adsorption capacity was 5 527.45 μg/g resin,the load of Pb2 ＋ resin can be desorbcd by 1 mol/L HN03, resin can be reused af- ter its desorption. The LS-5000 amino phosphoric acid type chelating resin can be used for the removal of Pb2. in the fruit juice and concentrate fruit juice, using 0.5 g resin, dealing with 50 mL containing Pb2. juice 4.0 μg/mL,a removal rate of Pb2 can reneh 00%
