There were reports that the concentrations of some commonly used PhACs were reached ppm level in some sewage and hospital wastewater. In addition, our laboratory does not have detection techniques for analysis of ultra-low trace amounts of PhAC. In order to more accurately optimize the removal conditions and investigate the adsorption mechanism, ppm level PhAC was chosen as the research object in this study. |

AS you said, the ppm level will not appear in the water environment regarding the concentration of new PhACs at present, though ppm level of concentration of PhACs were found in wastewater in some sewages and hospitals according to some reports. In addition, our laboratory can not trace any PhAC in ultra-low conditions due to techniques shortages. In order to optimize the removal conditions more precisely and investigate the absorptive mechanism , this study chooses concentration as a perspective to study ppm level PhAC. °ïÄãÐÞ¸ÄÁËһϣ¬¿´¿´ÄÜ·ñ¿ÉÐС£ |
