The Nanofiltration Technology of Metoprolol in the Water Environment

Abstract:

Metoprolol (MET) is a common kind of Pharmaceuticals and personal care products (PPCPs), which belongs to a new type of organic micropollutants. And conventional water and wastewater treatment technology cannot remove the MET effectively, so it is necessary to adopt nanofiltration technology for advanced treatment. The influence factors on removal of Metoprolol (MET) in water by nanofiltration are mainly investigated in the study. According to the results, the removal rate of MET by nanofiltration all can reach more than 99% with the initial concentration increasing. Then the removal rate of MET by nanofiltration at different pressure values, pH, salt ionic strength conditions are also studied. The results have shown that the removal rate is increasing from 90.0% to about 99.0% while pressure goes up. When pH=5, the removal rate of MET by nanofiltration is slightly increasing. And the removal rate is decreasing from more than 98.0% to more than 92.0% with salt ionic strength increasing.
