Abstract:In this study, the main water-absorbing materials in the market were used to study the absorption performance of Cd solution and Cd removal in soil Cd. The results showed that the solution absorption amount of Dongyang textile was significantly higher than those of other materials, reaching 46.2-49.4 mL/g, and the absorption amount of Cd could reach 0.009-0.016 mmol/g. The absorption amounts of Cd ions by different materials were superior to those of complexes formed by EDTA and GLDA with Cd. Soil Cd removal ability of Dongyang textile (30.4%-48.7%) was higher than that of needle felt (27.6%-43.1%) with the addition of EDTA and GLDA. And after treatment, soil pH slightly increased, while soil conductivity first increased and then gradually decreased to be consistent with the original soil conductivity, posing no adverse effects on soil. In conclusion, compare to other water-absorbing materials, Dongyang textile exhibited the best performance in absorbing Cd solutions and removing Cd from soil, which lays the foundation for the research and application of in-situ activation and surface adsorption technologies for heavy metals.
