在水泥-树脂-沸石（主要是斜发沸石）体系中，研究了载铯水泥离子交换树脂的水浸出及固钙机理。目前的工作重点是减少显着的Cs浸出锡条款的总Cs吸附在树脂上）混合天然未经处理和化学处理的沸石水泥。天然沸石的加入减少Cs释放高达70-75%（原来的量结合在树脂）在3年的浸出期的过程中。(C)1999 Elsevier Science Ltd.保留所有权利。
Water leaching of caesium (Cs)-loaded cemented ion exchange resin and the mechanism of Ca immobilization were studied in the cement-resin-zeolite (mainly clinoptilolite) system. Present work focuses on the reduction of significant Cs leaching tin terms of the total Cs adsorbed on the resin) by blending natural untreated and chemically treated zeolites to the cement. Addition of natural zeolites decreased Cs release by up to 70-75% (of the quantity originally bonded in the resin) in the course of a 3-year leaching period. (C) 1999 Elsevier Science Ltd.
