Acid retardation is a process which is used to separate acids from their corresponding salts. The feed solution is passed over a strong base anion exchange resin to separate the components. The resin has a greater affinity for the acid than for the salts, resulting in a chromatographic separation of salts from the acid whose movement is "retarded" by the greater affinity. The acid is then displaced from the resin by a fresh water pulse. In some cases the acid can be recovered in significantly higher concentration than the original feed solution.
The acid retardation process occurs due to the selective absorptivity of the hydronium ion on the anion exchange resin. The concentration of the acid inside the resin is much greater than in the external solution. Because the salt components of the influent stream do not diffuse into the resin phase, the mineral acid can thereby be separated from its salt. Theoretically, this phenomena is called a Donnan membrane effect.
Acid retardation is generally carried out in metal handling industries, where heavy metal ions are present in the process acids. In the metal plating industry, resins can be used to recover and recycle the acid used in pickling sheet metal, which would normally serve as a pollution problem and an economic expense.
酸迟缓是一个用来从相应的盐分离酸过程。饲料的解决办法是通过在一个坚实的基础阴离子交换树脂分离的组成部分。该树脂具有一种比为盐酸更大的亲和力,在色谱分离盐的酸,其造成的运动是“迟缓”的更大的亲和力。酸是由树脂,然后流离失所由淡水的脉搏。在某些情况下,酸溶液可以收回原饲料显着高浓度比。迟缓的酸过程中发生由于交换树脂的选择性吸收的阴离子的离子离子对。该树脂内的酸浓度远远低于外解决更大。由于进水流盐组件不扩散到树脂阶段,无机酸,从而可以脱离它的盐。理论上,这种现象被称为唐南膜效果。酸处理迟缓,一般都是由在金属工业,如重金属离子含量目前在这个过程中。在电镀行业金属,树脂,可用于回收及循环再造的酸洗薄板,这通常会成为一个污染问题和经济代价所使用的酸。
