There are many reviews on phytoremediation at home and abroad, but there are few studies on the adsorption of heavy metal pollution in sewage by root exudes. In fact, the use of super accumulation plants for phytoremediation of heavy metal contaminated soil is a hot spot in the current research on phytoremediation of soil pollution, and for on-site remediation, phytoremediation is to some extent more suitable than microbial remediation, with green, environmental protection, economic and other advantages. The effect of wheat root exudates on the adsorption of heavy metals Cr6+ and Cd2+ under different experimental conditions was studied by means of greenhouse culture. The results show that the adsorption removal rate initially increases significantly with time and then tends to stabilize. Under strong light conditions, the components of root exudates are more conducive to the adsorption of Cr6+ and Cd2+. The most suitable temperature for adsorption removal is around 20 °C, and high temperatures are not conducive to adsorption removal. However, under normal nutritional conditions, it is most favorable for the adsorption and removal of heavy metal ions Cr6+ and Cd2+. In conclusion, wheat root exudates have a certain adsorption and removal effect on Cr6+ and Cd2+, and the adsorption process changes with conditions.
