| Abstract: | The method of purifying hydrogen peroxide by using an ion exchange resin is popular in modern industry. Whereas it is imperfect and very important in studying and practical application, the dynamic exchange performance of D072 resin adsorbing minim metal cations in hydrogen peroxide was studied fundamentally in the experiment. By using resin columns, the breakthrough curves in different conditions were plotted in order to study the dynamic exchange performance of D072 in terms of cations in hydrogen peroxide. Flow rate, ratio of height to diameter, initial ion concentration, and feed solution constitute should all be taken into account. Thus optimal process conditions were determined and hydrogen peroxide industry was provided with scientific basis. |
