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.

The global increase in plastic production has significantly contributed to the contamination of aquatic environments with MPs. This study examined adsorption CV dye onto PS MPs ecosystems. BBD was utilized optimize conditions and evaluate effects key independent variables on process. sorption experiments were conducted using reaction mixtures containing at levels ranging from 0.1 1.5 g/L concentrations 5 20 mg/L. pH samples adjusted range 4 10, while duration interaction varied between 10 60 min. findings revealed that optimal rate for (84.96%) achieved a level 12.5 mg/L, dosage 1 g/L, 7, an 35 In this investigation, ZP particles transitioned − 45.6 16.8 mV following CV. Furthermore, kinetics most accurately described by pseudo-first-order model, demonstrating high R2 value 0.99. Langmuir isotherm (R2 = 0.99) further confirmed presence significant interactions molecules surface sorbent, highest capacity quantified 6.25 mg/g. highlights role microplastics as carriers harmful dyes, such CV, environments. It underscores urgent need research into environmental consequences microplastic pollution development strategies mitigate their impact.
