辐射接枝聚合是一种在常规聚合物中引入目标官能团的先进方法。通过将含磷酸的甲基丙烯酸酯单体接枝到聚乙烯非织造布上，直接合成了含磷酸的吸附剂。当10%的单体在10%甲醇和90%水的混合物中与200 kGy辐照的非织造布反应时，接枝率（Dg）达到185%，这是通过接枝后的增量重量来估计的。吸附剂的160%Dg显示，吸附容量为3 mmol/g吸附剂的铅和镉离子在柱模式。这些金属的去除可以在250 h-1的空速下进行。
Radiation induced graftpolymerization is a sophisticated tool for introducing the aiming functional group into the conventional polymer. Adsorbent having phosphoric acid was directly synthesized by grafting methacrylate monomer having phosphoric acid onto polyethylene nonwoven fabric. Degree of grafting (Dg), which was estimated by increment weight after grafting, reached 185% when the 10% monomer in the mixture of 10% methanol and 90% water was reacted with 200 kGy-irradiated nonwoven fabric. The adsorbent of 160% Dg revealed that adsorption capacity was 3 mmol/g-adsorbent for Pb and Cd ions in column mode. The removal of these metals could be performed with space velocity of 250 h-1.
