A novel electrochemical separation process using a polypropylene-supported membrane for simultaneous removal of nickel and manganese
Abstract
, and an extraction time of 5 hours. Remarkably, under these optimized conditions, impressive removal efficiencies were achieved for each heavy metal: 84% for Ni and 71% for Mn. The FESEM and AFM results of the membrane showed a relatively homogeneous surface structure with clear porosity and low roughness, indicating the integrity of the membrane and that it is not affected by the initial treatment. After the immersion of the membrane in the DEHP carrier, a marked change in the topography of its surface was observed in the form of increased roughness and partial fullness of pores, confirming the successful fixation of the carrier and the effectiveness of the membrane in the extraction process. The results confirm that the EME technique using the SLM is an effective way to extract heavy metals from water within the optimum mentioned operational condition.
