Abstract

Abstract

A pot test was conducted to study the effect of different chelating agents on absorption of As in soil by Pteris vittata, which included three biodegradable chelating agents, tetrasodium glutamate diacetate (GLDA), trisodium dicarboxymethylglycine (MGDA), ethylenediamine disuccinic acid (EDDS) and a traditional chelating agent, ethylenediaminetetraacetic acid (EDTA), with dosage ranged of 0~10 mmol/kg. It showed that all of the four chelating agents could significantly increase the biomass of Pteris vittata with the dosage of 1.25 mmol/kg. The bioavailable As content in rhizosphere soil was the highest when using 10 mmol/kg EDDS, which was 69.2% higher than CK. While As in the rhizosphere soil was 28.84% lower than that in the original soil, when the concentration of GLDA was 10.00 mmol/kg. The BCF of As was the highest (7.99), 1.7 times of that of CK, when treated with 5.00 mmol/kg EDDS. Accoding to Pteris vittata biomass and BCF of As, the accumulation of As of the above-ground part of the plant reached the maximum when treating with 5.00 mmol/kg MGDA, as high as 2648.65 μg/pot and 65.92% higher than CK group. Therefore, chelating agents GLDA and MGDA, which had been widely used in the field of soil remediation on Cd and Zn pollution, also had obvious potential for remediation on As contaminated soil.
