Gongye shui chuli, 1989 木文从高纯水的电阻率和州值的关系入手, 对混合柱内离子交换的机理进行了探索。提出了几个新概念: 混合柱内阴、阳离子交换树脂的交换强度, 交换强度比,以及阴、阳离子交换树脂的最佳体积比; 并推导了一个阴、阳离子交换树脂最佳体积比的公式。

Gongye shui chuli, 1982 一树脂污染的判断脱盐水处理中极其严重的问题是树脂的污染。所谓树脂污染是在离子交换过程中,交换势较高附着性能较强的离子或大分子之类物质,吸附或被交换到树脂上,而在再生时却难以洗脱下来,从而阻止了离子交换;或是在离子交换反应过程中生成难溶的沉积物,并沉积在树脂内部阻塞了离子交换扩散的通道,使交换容量大为降低。

Gongye shui chuli, 1984 在水的离子交换脱碱软化处理中, 由于在一般水质的情况下, H 离子交换出水呈酸性, 所以H 离子交换通常不单独使用, 而应与N a 离子交换组成并联或串联系统, 或配 合以加碱中和措施。

Gongye shui chuli, 2002 我国许多电厂在再生阴离子交换树脂时都习惯采用隔膜法生产的工业氢氧化钠,这种氢氧化钠中的杂质离子含量较高,会对阴离子交换树脂的性能产生很大的影响。就碱中杂质成分对阴离子交换树脂的影响,通过比较两种不同纯度的碱再生后的阴离子交换树脂的技术经济性,提出再生阴离子交换树脂时应优先选择纯度较高的碱。
