Biochar in the Remediation of Organic Pollutants in Water: A Review of Polycyclic Aromatic Hydrocarbon and Pesticide Removal.

This review explores biochar's potential as a sustainable and cost-effective solution for remediating organic pollutants, particularly polycyclic aromatic hydrocarbons (PAHs) and pesticides, in water. Biochar, a carbon-rich material produced from biomass pyrolysis, has demonstrated adsorption efficiencies exceeding 90% under optimal conditions, depending on the feedstock type, pyrolysis temperature, and functionalization. High surface area (up to 1500 m/g), porosity, and modifiable surface functional groups make biochar effective in adsorbing a wide range of contaminants, including toxic metals, organic pollutants, and nutrients.

Assessing the interaction between 4-methylbenzylidene camphor and microplastic fibers in aquatic environments: Adsorption kinetics and mechanisms.

Wastewater treatment plants play a crucial role in managing environmental pollutants, but they often release persistent contaminants like synthetic microplastic fibers (MPFs) into ecosystems. These microplastics, mainly from the textile industry and domestic washing of synthetic fabrics, are a major type of microplastic found in aquatic environments. Some harmful chemicals have an affinity for these microplastics, making them vectors for contaminants.
