杞柳对水中2,4-二氯苯酚的降解

TL;DRAbstract

Phytoremediation, which uses plants to treat polluted sites and groundwater, is a low-cost and promising method for pollution control. In this paper, phytoremediation of 2,4-Dichlorophenol (2,4-DCP) in water solutions by Salix integra was investigated. The efficiency, kinetics and mechanism of Salix integra to degrade 2,4-DCP were studied. The results showed that: in sterile and non-sterile treatments, Salix integra promoted 2,4-DCP degradation significantly compared with the control, removing at most 76.9, 81.1% of 20 mg•L^(-1) 2,4-DCP in 96h, respectively, and without Salix integra was 0%. In the kinetics experiment, 2,4-DCP concentration was measured at various time. The kinetics of 2,4-DCP degradation by Salix integra fitted the first-order kinetics equation. And it demonstrated that plant uptake and degrade contributed about 92.57% to the total 2,4-DCP removal, while microorganism did about 7.43%. We also found the positive effect of light on 2,4 DCP degradation by Salix integra i
