For rapidly and accurately obtaining the performance parameters of ion-exchange resins, an especial online column flow-injection electrochemical method and system (FIA-ECM) was designed. In the research, the waste strong acid type cation-exchange resin (WSCR) was used as test sample, which was again immersed in the saturated ferric trichloride solution and lubricant oil for long time and heated at 110 °C to further deteriorate its ion-exchange performance. And then, the orthogonal and the single factor experiments on WSCR were conducted by using the FIA-ECM system. Under optimized conditions, the resuscitation rate of WSCR reached to 90% which can reuse in industry for various water treatments. Besides, a new conclusion was also obtained by using the FIA-ECM system, namely, exchange capacity of SCR being in drying state is higher than that in wetting state, and new SCR can be transported and saved in drying state, thus can notably reduce transport costs. The conclusion has very important significance in water treatment industry using resins. Merits of FIA-ECM were higher in automation extent, lower in reagent consumption in the test, inexistent in personal errors, and conducive to environmental protection. It can be extended to automatically and rapidly determine performances of various resins or new developed materials with cation-ion exchange capacity and screening of various revitalizers for resins.

为了快速准确地获得离子交换树脂的性能参数，设计了一种特殊的在线柱流动注射电化学方法和系统（FIA-ECM）。在研究中，将废强酸型阳离子交换树脂（WSCR）用作测试样品，将其再次浸泡在饱和的三氯化铁溶液和润滑油中长时间，并在110°C加热以进一步破坏其离子-交流表现。然后，使用FIA-ECM系统对WSCR进行正交和单因素实验。在优化的条件下，WSCR的复苏率达到90％，可在工业中重复用于各种水处理。此外，利用FIA-ECM系统也得出了一个新的结论，即 处于干燥状态的SCR的交换容量高于处于润湿状态的SCR的交换容量，并且可以在干燥状态下运输和保存新的SCR，从而可以显着降低运输成本。该结论在树脂水处理行业中具有非常重要的意义。FIA-ECM的优点是自动化程度更高，测试中试剂消耗更低，不存在人为错误并且有利于环境保护。它可以扩展为自动和快速地确定具有阳离子交换能力的各种树脂或新开发材料的性能，并筛选各种树脂活化剂。FIA-ECM的优点是自动化程度更高，测试中试剂消耗更低，不存在人为错误并且有利于环境保护。它可以扩展为自动和快速地确定具有阳离子交换能力的各种树脂或新开发材料的性能，并筛选各种树脂活化剂。FIA-ECM的优点是自动化程度更高，测试中试剂消耗更低，不存在人为错误并且有利于环境保护。它可以扩展为自动和快速地确定具有阳离子交换能力的各种树脂或新开发材料的性能，并筛选各种树脂活化剂。
