第二章首先以xyz - 1型电化学抑制柱为例，分析了电化学抑制柱的抑制过程得出影响抑制容量的主要因素主要是抑制柱的电流效率和离子交换膜的极限电流密度，因此采用中等交换能力的离子交换树脂作为抑制室的填料以提高电流效率，在通常情况下电流效率可达到90以上；在选用同种离子交换膜的前提下，可通过增加离子交换膜的有效面积达到提高极限电流的目的从而提高抑制柱的抑制容量，因此提出了多级抑制的概念并据此研制了共电极式高容量电化学抑制柱，该抑制柱最高可将流速为1 . 0ml / min ，浓度为200mmol / l电导率超过10000 s ? cm ~ ( - 1 )氢氧化钠溶液抑制为电导率低至8 . 9 s ? cm ~ ( - 1 )的纯水，并且具有稳定性高、分析结果准确等优点。
