Phosphogypsum (PG) wastes, including solid-state PG and liquid-state leachate, are industrial byproducts generated during the production of phosphoric acid. It is great concern due to large-scale product accumulation environmental geological hazards. Harmless treatment green chemical resource utilization techniques emerge be critical solutions for solving waste problem. This review aims comprehensively summarize recent advances in harmless treatment, recovery, valorization wastes. The technique advancements regarding decontamination, with different physical, chemical, thermal, biological approaches summarized. Additionally, comprehensive physical chemistry mechanisms underneath strategies leachate have also been discussed. For future work, challenges perspectives highlighted. With systematic information on these aspects, we expect this will serve as a guideline young generations working recovery.

Exposure to excessive concentrations of fluoride in potable water is harmful human health; therefore, its limitation deemed necessary. Among the commonly applied technologies, adsorption selected, as it a highly effective, simple, and economically efficient treatment. In present study, several combinations chitosan (CS), orange peels (OP), activated carbon (AC), MgO were synthesized tested adsorbents order find most effective derivative for extraction. The impact adsorbent dosage, pH level, contact time, initial concentration was investigated assess feasibility chitosan/orange peels/activated carbon@MgO composite. According results, modification with AC, OP, unique (CS/OP/AC@MgO), especially acidic conditions (pH 3.0 ± 0.1) by using 1.0 g/L adsorbent, demonstrated highest efficiency F removal, up 97%. pseudo-second (PSO) model Langmuir isotherm fit better experimental CS/OP/AC@MgO, providing Qm = 26.92 mg/g. Thermodynamic analysis confirmed spontaneous nature process. structure morphology modified OP/CS@AC-Mg extensively characterized BET, XRD, FTIR, SEM techniques.

The presence of fluorine and phosphorus in phosphogypsum leachate directly affects the local ecological environment groundwater quality. This paper examined adsorption characteristics by red clay near a landfill Guizhou Province, China, under different pH values, initial concentrations, soil dosages, particle sizes soil. Response surface methodology (RSM) was employed to optimize three factors (pH, concentration, dosage) selected Box-Behnken design that have great influence on single-factor adsorption. optimum condition for identified as = 3, concentration 91.08 mg/L, dosage 5.31 g, while 4.17, 99.49 5.82 g. Langmuir equation, quasi-secondary kinetic model, Elovich model were used fitting, which demonstrated good fitting. Finally, comparing characterization results scanning electron microscopy (SEM-EDX), X-ray diffraction (XRD), infrared spectroscopy (FTIR), process accompanied electrostatic addition chemical ligand exchange, result multiple effects. findings this study will provide reference prevention, control, management fluoro-phosphorus pollution dumps.
