The influence of particle size distribution on properties of heterogeneous bipolar ion exchange membranes
Original language description
The primary focus of this study is the influence of particle size distribution in one of the two ion-exchange resins (Amberlite IRC747 and Purolite C120E) used in cation-exchange layer on properties of BM. Four samples of bipolar membranes with different particle size distribution of IRC747 were prepared. Preparation samples consist of five steps, washing and drying of ion exchange resin, grinding of ion exchange resin on a vibrating mill to four different particle size distribution, homogenization with polyethylene binder, extrusion of monopolar membranes and joining of monopolar layers on the press. Different particle size distribution was obtained through different grinding time and weight of milled resin. It was checked after grinding by device from Malvern Mastersizer 2000 with laser diffraction. Mean particle size of IRC747 was in the range 4,1 – 10,5 μm, which is lower than the value for used strong anion a cation exchange resins (17 resp. 13 ± 3 μm). Bipolar membranes with four different particle size distribution of IRC747 were characterized by Current-Voltage curve in solution of 0,5 M KCl according to standard operating procedure. Technological tests EDBM were also carried out with prepared samples of bipolar membrane in combination with standard Ralex anion exchange and cation exchange membranes reinforced by polypropylene fabrics. During these tests performed according to the standard operating procedure, the sodium sulfate solution was desalted to 10% of the initial conductivity corresponding to the concentration 20 g/l Na2SO4. Sulfuric acid and sodium hydroxide were obtained as products in circuits with initial concentration 5 g/l H2SO4 resp. NaOH. Test duration, salt flow intensity, current efficiency and energy consumption were compared for bipolar membranes with different particle size distribution. Obtained results showed no significant influence of particle size distribution of ion-exchange resin Amberlite IRC747 on the properties of bipolar membrane.
