摘要：

Removal of technetium from radioactive waste has become attractive due to its huge environmental hazard. Herein, a series of n-alkyl-imidazolium ionic liquids functionalized cellulose microspheres (MCC-[C(n)VIm]Br, n = 2, 4, 6, 8, 10) were synthesized by radiation method, and their grafting regularity were investigated. In order to explore the effect of alkyl chain length on adsorption performance, the adsorption behaviors of MCC-[C(n)VIm]Br for TcO4-/ReO4- were researched in detail via batch and column experiments. MCC-[C(n)VIm]Br exhibited high ReO4- adsorption efficiency over a wide pH rang...
