摘要:
Environmental problems arising from acidic waters containing aluminum and copper from condensing boilers can be adequately addressed using membrane processes. This paper deals with simultaneous neutralization and separation of aluminum and copper ion from acidic waters containing aluminum and copper traces through permeation through capillary composite membranes made of polypropylene with carboxymethyl cellulose (PP/CMC) inclusions. The optimum working parameters for the carboxymethylcellulose composite membrane were determined: operating time and pH of the receiving phase. Simultaneously with the quantitative removal of aluminum and copper ions, an almost neutral pH is obtained, compatible with the natural waters in which it can be dispersed.
