英国的研究工作者为了给水处理和湿法冶金过程提供基本资料,以加强应用基础,研究了氢氧化铝凝胶与强酸性阳离子交换树脂(Amberlite IR 120)之间的离子交换,氢氧化铝凝胶是由硫酸铝和氨水溶液配制而成的。整个离子交换是一种酸碱反应,由于两种主要反应物是固态的,故反应比较缓慢地趋向平衡(>几个小时)。初步研究表明,采用逐步添加硫酸铵的办法,使离子强度由
In order to provide basic information for water treatment and hydrometallurgical processes and to strengthen the application base, British researchers studied the ion exchange between aluminum hydroxide gel and strongly acidic cation exchange resin (Amberlite IR 120), aluminum hydroxide condensate Glue is made from aluminum sulfate and ammonia solution. The entire ion exchange is an acid-base reaction, and the reaction tends to equilibrate more slowly (> a few hours) as the two main reactants are solid. Preliminary studies have shown that the gradual addition of ammonium sulfate to make the ionic strength by
