Microplastics (MPs) are emerging pollutants that pose significant risks to ecosystems due their inherent toxicity, capacity accumulate various pollutants, and potential for synergistic impacts. Given these concerns, the focus of this research is on critical need effective MPs removal from aquatic environments. Using BBD method, study aimed identify key parameters affecting by algal biomass aqueous solutions. The investigation specifically analyzed effects varying initial PS concentrations (100 900 mg/L), pH values (4 10), reaction durations (20 40 min), C. vulgaris dosages (50 400 mg/L). Data analysis indicated QM best described experimental findings, leading identification optimal conditions removal: a 7.5, time 31.90 min, dosage 274.05 mg/L, level 789.37 mg/L. Under conditions, achieved maximum efficiency 73.01% PS. These outcomes demonstrate in efficiently removing water. Furthermore, using algae as green, eco-friendly alternative conventional chemical coagulants offers practical sustainable approach addressing pollution our water systems.

Biochar has attracted attention for its capability to remove phosphorus (P) from wastewater. However, the poor dispersion and limited adsorption capacity of unmodified biochar prevent wide usage in water remediation. Herein, sludge was modified using lanthanum nitrate improve removal P aqueous solutions. Scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), photoelectron (XPS) were used elucidate modification mechanisms biochar. Furthermore, performance determined through kinetics isotherm model fitting. The results showed that process successfully introduced lanthanum-containing functional groups into considerably improved complexation ion-exchange capacity. maximum experimental phosphate 140.237 mg/g at pH 3.0. processes accorded with Freundlich model, which indicates successful onto via multilayer adsorption. mechanism dominated by chemisorption, mainly involved inner-sphere complexation, precipitation, electrostatic attraction. Meanwhile, desorption experiments demonstrated satisfying recycling 72.3% retention after sixth cycle. dynamic study revealed had long sustainable treatment durations 7.58 9.08 h adsorbent dosages 1 2 g, respectively, proves feasibility as a cost-effective efficient phosphate-polluted water.

This study aims to enhance the resource utilization of waste sludge and mitigate environmental risks associated with Pb2+ contamination. Municipal biochar (MBC) pharmaceutical (PBC) were selected as experimental subjects. The experiment systematically investigated influential factors affecting adsorption, including adsorbent dosage, reaction time, pH. physicochemical attributes (BC) assessed through techniques such scanning electron microscopy, Fourier-transform infrared spectroscopy, X-ray diffraction analysis, point zero charge analysis. adsorption process was described by pseudo-second-order kinetic model Freundlich isotherm model, highest capacities established 18.56 mg/g 19.07 for MBC PBC, respectively. on BCs is related chemical physical mechanisms. Ligand bonding, monolayer chemisorption, electrostatic interactions pore filling considered possible mechanisms involved in system. It shown that PBC are efficient adsorbents removal water.

Magnetic biochar (MBC), as an environmentally friendly material, has been extensively used for the remediation of soil and groundwater contamination. The retention release nanoplastics (NPs) with carboxyl (NPs-COOH) or amino functionalization (NPs- NH2) in saturated porous media were investigated under varying conditions ionic strength (IS), MBC addition, humic acid (HA) concentration, cation types. reversible irreversible NPs was examined by altering IS, increasing solution pH, inducing exchange. results revealed that enhanced surface roughness media, thereby inhibiting NPs' transport. HA promoted NPs-NH2 transport more effectively than NPs-COOH due to electrostatic repulsion, steric hindrance, competition deposition sites. Under a reduced IS increased portion retained released, showing greater NPs-COOH, indicating retention. Additionally, stronger charge-shielding cation-bridging effects Ca2+ significantly NPs. Cation exchange resulted less being most irreversibly deeper primary minima. However, small number remobilized electrical double layer expansion, deprotonation, exchange, These findings provide valuable insights into fate environment.
