Synergistic Remediation of Cadmium Pollution in Saline-Alkali Soil by Hydrogel and .

The cadmium (Cd) in saline-alkali soil poses a serious threat to the ecological environment and human health. , as a hyperaccumulator plant, can remediate Cd in saline-alkali soil, but the efficiency of phytoremediation is low. To improve the remediation effect of Cd pollution in saline-alkali soil, this study for the first time uses the synergy of hydrogel and for the remediation of Cd in saline-alkali soil. Hydrogel possesses excellent mechanical properties and outstanding adsorption properties. In addition, the hydrogel increases the content of some nutrient elements in the soil and improves the physicochemical properties of the soil. The water retention capacity of the hydrogel and the improvement of the physicochemical properties of the soil further promote the growth of . Meanwhile, both the hydrogel and have a positive impact on microorganisms. Our experiment provides a brand-new way for the remediation of Cd pollution in saline-alkali soil and is of great significance for soil health and ecological protection.
