Degradation of imazalil enantiomers in soil using capillary electrophoresis

A rigorous analytical method was presented by Bao-Lin Chu, Bao-Yuan Guo, Zhenlei Peng, Zhihua Wang, Guangsheng Guo, and Jin-Ming Lin to uncover the degradation behavior of the two enantiomers of fungicide imazalil in soil using cyclodextrin-modified capillary zone electrophoresis (CZE). Sensitive, rapid and quantitative determination of both enantiomers of imazalil in soil was achieved by using β-CD modified capillary electrophoresis with limits of detection of 0.24 μg/mL and 0.26 μg/mL for (-)- and (+)-imazalil, respectively. The analysis time was less than 10 min. There was little interference in the determination of the imazalil enantiomers in the complicated soil matrix. The method was used to study the enantioselectivity of imazalil degradation in soil under laboratory conditions. The photolytic degradation, biodegradation and the uptake by wheat contributed to the degradation of imazalil simultaneously. Actually, non-enantioselective degradation of imazalil was found due to the soil property. However, a robust method was provided to investigate the environmental behavior and fate of both enantiomers of imazalil in soil.
