Summary: Cadmium pollution in crops is a serious concern for the environment and human health. This study investigates the effects of using biochar and selenium together to remedy soil cadmium pollution and uses peanut crops as the target. The results show that the combined application of biochar and selenium can significantly increase peanut yield and reduce cadmium content in peanut seeds, while also impacting soil properties and microbial community structure.

Summary: Water pollution caused by heavy metals is a serious threat to the environment and human health. This study developed a novel MnFe2O4 loaded biochar, which was prepared and modified from agricultural waste straw using the sol-gel method, to efficiently remove cadmium (Cd) from water. The results showed that the as-prepared composites had a significantly higher Cd adsorption capacity compared to the original biochar. The spinel loaded biochar exhibited a strong anti-interference ability in binary and quaternary systems, and its magnetic properties facilitated easy separation and recovery from aquatic solutions, with little decrease in adsorption capacity after multiple cycles.

Summary: The addition of graphene-modified rice straw biochar to heavy metals-contaminated soil can significantly reduce the accumulation of heavy metals in plants, thereby reducing the heavy metal content in plants. The modified biochar performs better than regular rice straw biochar in reducing the accumulation of Cd and Pb in the soil.

Summary: Cadmium contamination is a serious threat to both humans and aquatic life, and it is essential to research methods to remove it from wastewater in order to protect the environment. This study used selenium-enriched foliar fertilizer sprayed on agricultural and forestry waste straw to create biochar, which, when treated with calcium chloride, showed efficient removal of Cd2+ from water. The results indicated that biochar produced at 700 degrees C had the highest adsorption effect, and the main mechanisms involved electrostatic adsorption, ion exchange, and complexation of oxygen functional groups. This work offers a promising strategy for the recovery of agroforestry waste and the overall utilization of rice straw.

Summary: This study explored the use of biochar or modified biochar techniques to reduce the potential pollution risk of Cd in contaminated rice straw. It was found that straw biochar and phosphorus modified biochar could enhance soil properties and reduce the bioavailability of Cd, effectively minimizing Cd availability in soil and reducing the pollution risk of Cd in rice straw.

Summary: Metal oxide-modified biochar showed excellent adsorption performance in wastewater treatment. In this study, iron-manganese (Fe-Mn) oxide-modified biochar (BC-FM) was synthesized using rice straw biochar, and its adsorption process, removal effect, and mechanism of cadmium (Cd) adsorption in wastewater treatment were investigated. The results demonstrated that BC-FM had a significantly higher adsorption capacity for Cd compared to other modified biochars mentioned in the literature. The Cd adsorption by BC-FM followed a spontaneous chemical adsorption mechanism. Additionally, BC-FM exhibited good reusability and stability. Therefore, metal oxide-modified biochar can be an efficient adsorbent for treating Cd-contaminated wastewater.

Summary: This study compared the removal efficiency of arsenite [As(III)] and arsenate [As(V)] using peanut shell biochar (PSB) and modified peanut shell biochar (MPSB) in aqueous solutions. The modification process involved KMnO4 and KOH. MPSB showed higher sorption efficiency than PSB for both As(III) (86%) and As(V) (91.26%) at pH 6, initial concentration of 1 mg/L, adsorbent dose of 0.5 g/L, and equilibrium time of 240 min at 100 rpm. The adsorption mechanism was suggested to be multi-layer chemisorption according to the Freundlich isotherm and pseudo-second order kinetic model. Fourier transform infrared spectroscopy indicated the significant contribution of -OH, C-C, C--C, and C-O-C groups in the adsorption process. Thermodynamic study confirmed the spontaneous and endothermic nature of the adsorption process. The results also showed that PSB and MPSB can be regenerated and reused for three cycles. This study highlights the potential of peanut shell biochar as a cost-effective, environmentally friendly, and efficient adsorbent for arsenic removal from water.

Summary: This experiment investigated the removal efficiency and mechanisms of potassium permanganate modified biochar (MBC) on arsenic and cadmium. The results showed that MBC had significantly higher sorption capacities for arsenic and cadmium in a coexisting solution compared to a single solution. The formation of ternary complexes and electrostatic adsorption were the main mechanisms for MBC to remove cadmium and arsenic. MBC proved to be an effective material for simultaneous removal of arsenic and cadmium from contaminated water.

Summary: This study investigated the dynamic effects and potential mechanisms of wheat-straw, wheat-straw biochar, and biologically modified wheat-straw on the adsorption, leaching behavior, chemical fractions, and bioavailability of cadmium. The research revealed that biologically modified wheat-straw had the highest biosorption capacity for Cd and significantly reduced Cd concentration in leachate compared to wheat-straw biochar and wheat-straw treatments. These findings suggest a novel approach for the development of functional materials and strategies for eco-friendly and sustainable trace metal remediation in contaminated soil and water.

Summary: The study showed that indirect use of municipal sewage sludge (MSS) alongside Pennisetum hybridum plants significantly increased crop yield and nitrogen content in the plants, while also enhancing organic matter and nitrogen content in the planted soil. The heavy metal contents in the soil at the bottom of the MSS ditch were not significantly affected, indicating the safe utilization of MSS for sustainable agriculture and environmental purposes.
