Removal of Pesticides by Organic Montmorillonite Composites

Abstract:

The removal of pesticides (quintozene, α-BHC, Aldrin and pp′-DDT) by phenyltrimethylammonium bromide (PTMAB) modified montmorillonites(PTMAB-MMT) was investigated. The results showed that these four kinds of pestcides have high affinity with PTMAB-MMT. The composites were characterized by FTIR and XRD. Further, the removal experiments of pesticides in ginseng extracts were carried out. The Ginsenosides were analyzed by high performance liquid chromatography/mass spectrometry showed that the loss of Ginsenosides was less than 4%. It can be concluded that the PTMAB-MMT is a promising material in pesticide pollution treatment
