The contamination of water and soils with heavy metals poses a significant environmental threat, making the development effective removal strategies global priority. Hence, determination can play an essential role in monitoring assessment. In current research, ensemble machine learning (ML) models (i.e., Random Forest Regressor (RFR), Adaptive Boosting (Adaboost), Gradient (GB), HistGradientBoosting, Extreme (XGBoost), Light Gradient-Boosting Machine (LightGBM)) were applied attempt to predict adsorption efficiency several Pb, Cd, Ni, Cu, Zn) according different factors including temperature, pH, biochar characteristics. Data collected from open-source literature review 353 samples. At first stage, data processing was performed outliers' scaling for better modeling applicability; whereas, second stage predictive conducted. results showed that XGBoost model attained superior accuracy comparison other by achieving highest coefficient (R2 = 0.92). research extended investigate feature importance analysis which indicated initial concentration ratio pH most influential toward followed Pyrolysis while features like physical properties as surface area pore structure had minimal effect on efficiency. These findings highlighted using ML guiding solutions it provides efficient prediction ease selection application.

The global impact of water and soil contamination has become a serious issue that affects the world all living beings. In this sense, multiple treatment alternatives have been developed at different scales to improve quality. Among them, biochar suitable alternative for environmental remediation due its high efficiency low cost, raw material used production comes from residual biomass. A is carbonaceous with interesting physicochemical properties (e.g., surface area, porosity, functional groups), which can be prepared by synthesis methods using agricultural wastes (branches banana rachis, cocoa shells, cane bagasse, among others) as feedstock. This state-of-the-art review based on general description remediation. Biochar’s production, synthesis, uses also analyzed. addition, work shows some thus several applications, like removing heavy metals, oil, dyes, other toxic pollutants.

Abstract Traditional fertilizers are highly inefficient, with a major loss of nutrients and associated pollution. Alternatively, biochar loaded phosphorous is sustainable fertilizer that improves soil structure, stores carbon in soils, provides plant the long run, yet most biochars not optimal because mechanisms ruling properties poorly known. This issue can be solved by recent developments machine learning computational chemistry. Here we review phosphorus-loaded emphasis on chemistry, learning, organic acids, drawbacks classical fertilizers, production, phosphorus loading, release. Modeling techniques allow for deciphering influence individual variables biochar, employing various supervised models tailored to different types. Computational chemistry knowledge factors control binding, e.g., type compound, constituents, mineral surfaces, binding motifs, water, solution pH, redox potential. Phosphorus release from controlled coexisting anions, adsorbent dosage, initial concentration, temperature. Pyrolysis temperatures below 600 °C enhance functional group retention, while 450 increase plant-available phosphorus. Lower pH values promote release, higher hinder it. Physical modifications, such as increasing surface area pore volume, maximize adsorption capacity biochar. Furthermore, acid affects low molecular weight acids being advantageous utilization. Lastly, biochar-based 2–4 times slower than conventional fertilizers.
