PAR基红麻纤维的制备及其对Ni~(2+)、Cu~(2+)、Cd~(2+)的吸附性研究

Studies on the syntheses of kenaf containing PAR and its adsorption properties for Cd~(2+),Cu~(2+)an

摘要: 红麻纤维经环氧基活化后与吡啶(2-偶氮-4)间苯二酚(PAR)接枝反应,制得一种改性红麻纤维.测定了该纤维对Ni2+、Cu2+、Cd2+的吸附性能.结果表明:在一定条件下,改性纤维对Cu2+、Cd2+的吸附性能较好,而对Ni2+的吸附性能一般.

Abstract: A modified kenaf was prepared by epoxy kenaf with 4-(2-pyridylaxo) resorcinol.The adsorption properties of modified kenaf on nickel(Ⅱ),copper(Ⅱ) and cadmium(Ⅱ) ions were investigated.The results show that the absorbility of the modified kenaf for cadmium(Ⅱ) and copper(Ⅱ) are fairly good,but for nickel(Ⅱ) is poor.
