摘要：
Influence of pH on sorption of copper (II) and nickel (II) cations by complexing ANKB-35 ion - exchange resin has been investigated. It has been shown that sorption efficiency increases with increasing pH of solution up to pH values corresponding to hydrate formation of cations (II) without further change. The growing of the solution pH - value at the beginning of the sorption process depending on pH of the initial solution and then its decrease has been observed. It has been established that this phenomenon is connected with the hydrolysis of the resin fixed ions and with imino - group nitrogen influence on the ampholyte filling degree by two charged cations, that has been confirmed by using differential scanning calorimetry data.
