| dc.title | E coli, Cu²⁺, Pb²⁺ removal from storm water by IOCS, CTAB or PolyDADMAC modified IOCS | en_US |
| dcterms.abstract | Storm Water was found to be a precious resource which can be recycled and storage. However, contaminants such as pathogens, heavy metal ions etc. were found to be threatening the quality of storm water. Researches have been conducted to investigate the effective technologies to treat the contaminants. Nowadays, the importance of storm water has raised more and more attention. In our study, iron oxide coated sand and its production after modification by CTAB and PolyDADMAC were applied to investigate the performance of E coli and Cu²⁺ and Pb²⁺ removal from storm water. And IOCS was found to have better capacities in E coli adsorption in column tests while the PolyDADMAC-IOCS had a better performance in batch tests. As for the performance of Cu²⁺ and Pb²⁺ removal from storm water, the results of batch test were presented to tell us that CTAB-IOCS and IOCS were respectively a better adsorbent for Cu²⁺ and Pb²⁺. Then relationship between E coli adsorption and pH and TOC were studied in column test and batch test. Besides relationship between Cu²⁺, Pb²⁺ adsorption and pH was also studied. The results were found out that with the increasing of Cu²⁺ and Pb²⁺ adsorption, the pH of the solution was decreasing. | en_US |
