Phosphogypsum (PG), a byproduct during the phosphoric acid production process, also known as wet contains complex and diverse impurities, resulting in low utilization considerable accumulation. This leads to massive waste of land resources series environmental pollution problems. Given current urgent ecological situation, developing impurity removal processes with energy consumption high efficiency, exploring valuable resource recovery, preparing value-added PG products, broadening comprehensive ways are significant strategies promote sustainable development phosphorus chemical industry. review comprehensively summarizes advantages disadvantages existing technologies probes into future direction, which provides references ideas for subsequent research.

The migration of heavy metals and radionuclides is interrelated, this study focusses on the interaction complex influence various toxicants. rehabilitation radioactively contaminated territories has a character based scientifically supported measures to restore industrial, economic, sociopsychological relations. We aim for achievement pre-emergency levels hygienic norms radioactive contamination output products. This, in its sum, allows further economic activity these without restrictions basis natural actions autoremediation. Biosorption technologies bacterial biomass remain promising direction remediation soils with that help immobilise consolidate contaminants. A comprehensive understanding biosorption capacity preparations selection more effective techniques elimination contaminants, as well overcoming differences between laboratory results industrial use. Observation monitoring make it possible evaluate process identify regions disturbed balance harmful substances. soil application phosphogypsum, by-product chemical industry, bioremediation processes considered.

The implementation of a sustainable development strategy holds the potential to enhance productivity, profitability, and overall efficiency by leveraging by-products from other industries. In plaster manufacturing substitution natural gypsum with synthetic is worth exploring. Phosphogypsum (PG) represents significant fraction production, arising as by-product phosphoric acid manufacturing. However, presence impurities in PG, particularly phosphorus, poses challenges its use material. To identify phases present quantify their occurrences understand effects on dehydration hydration processes, our study aimed examine simplified models. These models are specifically designed provide insights into underlying mechanisms governing reactivity hemihydrate. Pure brushite were synthesized, mechanical mixing was carried out explore how affects characteristics gypsum. Additionally, solid solution Ca(SO4)1-x(HPO4)x·2H2O, where 0 < x 1, prepared characterize syncrystallized HPO42− well this impurity typical cases. synthesized materials underwent physical chemical characterization using SEM, XRD, IR spectroscopy, DSC, pH conductivity measurements, ion chromatography. results demonstrated that ions can substitute for sulfate form solutions. maximum quantity lattice approximately 10%, leading crystallization sand rose shape rather than needle crystals. As concentration increases, new phase known ardealite (Ca(SO4)1-x(HPO4)x·2H2O) 0.42 0.54 emerges, followed (CaHPO4·2H2O). During calcination at 160 °C, mixture monetite formed exhibits different properties compared counterpart. ions, transformation anhydrite III II occurred higher temperatures pure calcined samples indicate products caused delay hydration, observed temperature °C. At temperature, begins crystallize, it characterized inert nature, exhibiting no water. This explains decrease setting times rises. Moreover, induced process. Our research revealed adjusting mitigate retarding effect associated impurity, suggesting an industrial tendency lowest possible during process PG containing phosphate impurity. addition, we have water lower values significantly accelerate times.
