The prepared products were crosslinked with epichlorohydrin(ECH),the crosslinked carboxymethyl konjac glucomannan(CCMKGM) was able to adsorb Pb~(2+) effectively,it has good adsorptive performance and the desorption percentage is high.

• 将制得的CMKGM用环氧氯丙烷交联,结果表明交联羧甲基魔芋葡甘聚糖(CCMKGM)能有效的吸附水中的Pb2+; 且再生后的CCMKGM吸附性能好,解吸附百分率高。
