Description

В ходе обработки Cu-катионита раствором гидросульфита некоторое количество меди переходит в фильтрат, а больща  часть ее закрепл етс  на зернах катионита в виде тонкодиспергированной и равномерно распределенной меди. Медь, нанесенна  на катионит, не закрывает активные группы катиопита и практически не снижает его ионообменную способность .During the treatment of the Cu-cation exchanger with a hydrosulfite solution, some copper is transferred to the filtrate, and most of it is fixed on the cationite grains in the form of finely dispersed and uniformly distributed copper. Copper deposited on a cation exchanger does not close the active groups of catiopite and practically does not reduce its ion-exchange capacity.

№ 119484No. 119484

Медь электро оионообменника одновременно играет роль катализатора в окислительно-восстановительном процессе поглощени  растворенного в воде кислорода путем передачи электронов от органической части катионита к растворенному кислороду. Восстановление способности отработанного электроноионообменника к поглощению солей осуществл етс  регенерацией обычным приемом, примен емым в водоподготовке. Восстановление способности к поглощению растворенного кислорода достигаетс  за счет обработки катионита раствором гидросульфита.Copper electro-ion exchanger simultaneously plays the role of a catalyst in the redox process of absorption of oxygen dissolved in water by transferring electrons from the organic part of the cation exchanger to dissolved oxygen. Restoration of the ability of the spent ion-exchanger to absorb salts is carried out by regeneration by the usual method used in water treatment. Recovery of the ability to absorb dissolved oxygen is achieved by treating the cation exchanger with a hydrosulfite solution.

Предмет изобретени Subject invention

Способ очистки воды с применением катионитов типа сульфоугл , отличающийс  тем, что, с целью одновременного см гчени  и обескислороживани  воды, катионит предварительно обрабатывают раствором медного купороса с последующим восстановлением поглощенных ионов меди щелочным раствором гидросульфита натри .The method of water purification using sulfonated cation exchangers, characterized in that, in order to simultaneously soften and deacidify the water, the cation exchanger is pretreated with copper sulfate solution with subsequent recovery of the absorbed copper ions with an alkaline solution of sodium hydrosulfite.
