【摘要】 通过对ＮａＯＨ－Ｈ２Ｏ－Ｃ２Ｈ５ＯＨ－Ｎａ２ＳＯ４（ＮａＣｌ）体系相平衡规律的研究，提出了循 环利用阴离子交换树脂再生溶液的方法，该方法利用乙醇调整再生液体系的相平衡，分离 出再生产物，实现再生液的循环使用，防止了水体污染和资源浪费．更多还原

【Abstract】 The method by which the waste liquid in regenerating negative ion exchange resin can be circulated was put forward. This technique adjusts the waste liquid by studing the balance law of NaOH - H2O - C2H5OH - Na2SO4(NaCl) system. The pollution of was ie liquid and the waste of resource were eliminated.更多还原
