“…It affects the deprotonation and protonation of functional groups, as well as the morphology of heavy metal ions, among other things. 39 From Fig. 3(b), the adsorption capacity of ZIF-8/SA for the contaminated solution significantly increased when the pH increased from 3 to 7.…”

“…It is prepared by modifying traditional biochar through ball milling, chemical reactions, and other modification methods. Compared with traditional biochar, modified biochar has a larger specific surface area and more abundant oxygen-containing functional groups, providing many heavy metal adsorption sites [ 23 ]. Li and Shi found that the specific surface area, pore volume, and microporous volume of iron and dicyandiamide co-modified walnut shell biochar were 967.1084 m 2 ·g −1 , 0.7425 cm 3 ·g −1 , and 0.4624 cm 3 ·g −1 , respectively, which were 3.39, 6.42, and 8.81 times that of the original biochar [ 24 ].…”

Contamination with cadmium (Cd) is a prominent issue in agricultural non-point source pollution in China. With the deposition and activation of numerous Cd metal elements in farmland, the problem of excessive pollution of agricultural produce can no longer be disregarded. Considering the issue of Cd pollution in farmland, this study proposes the utilization of cross-linked modified biochar (prepared from pine wood) and calcium alginate hydrogels to fabricate a composite material which is called MB-CA for short. The aim is to investigate the adsorption and passivation mechanism of soil Cd by this innovative composite. The MB-CA exhibits a higher heavy metal adsorption capacity compared to traditional biochar and hydrogel due to its increased oxygen-containing functional groups and heavy metal adsorption sites. In the Cd solution adsorption experiment, the highest Cd2+ removal rate reached 85.48%. In addition, it was found that the material also has an excellent pH improvement effect. Through the adsorption kinetics experiment and the soil culture experiments, it was determined that MB-CA adheres to the quasi-second-order kinetic model and is capable of adsorbing 35.94% of Cd2+ in soil. This study validates the efficacy of MB-CA in the adsorption and passivation of Cd in soil, offering a novel approach for managing Cd-contaminated cultivated land.
