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 potential of Aspergillus sp. for plastic biodegradation is a promising approach environmentally friendly waste management. Various research studies have been conducted to optimize conditions that enhance the plastics and understand genetic basis species. By performing this investigation, we discussed role various species in decomposition polymers. Most grow within pH range 4 6. 37.5% showed grows optimally at 30 °C. Scanning electron microscopy (SEM) Fourier transform infrared (FTIR) tests were used 34.61% 32.69% different studies, respectively. It has observed fungi can biodegrade polymers more effectively size 20–100 μm. (34.21%) focused on 21 days. highest percentage (44%) low-density polyethylene (LDPE) by dominant sp., including A. niger, flavus, oryzae, play significant microplastics. Enzymes such as laccase, esterase, peroxidase, lipase, urease crucial roles degradation plastics. Laccase utilizes oxygen generate reactive species, breaking polymer chains. Esterase cleaves into fragments, while peroxidase generates radicals degradation. Lipases also contribute specific substrates. In general, it be said fungal successful degrading

Abstract Microplastics (MPs), as carriers of organic pollutants in the environment, have become a growing public concern recent years. Tetracycline (TTC) is an antibiotic that can be absorbed by MPs and harmful effect on human health. Therefore, this study was conducted with aim investigating adsorption rate TTC onto polyvinyl chloride (PVC) MPs. In addition, mechanism process studied using isothermal, kinetic, thermodynamic models. For purpose, experimental runs Box-Behnken model were designed to investigate main research parameters, including PVC dose (0.5–2 g/L), reaction time (5–55 min), initial concentration (5–15 mg/L), pH (4–10). Based findings, highest (93.23%) obtained at 10, contact 55 min, adsorbent 1.25 g/L, 10 mg/L. The found followed pseudo-second-order Langmuir Thermodynamic data indicated spontaneous, exothermic, physical. Increasing ion decreased adsorption, distilled water had while municipal wastewater lowest adsorption. These findings provide valuable insights into behavior pollutants, underscoring importance conducting additional implementing measures mitigate their detrimental effects health environment.

Abstract MPs have raised significant public concern due to their role as carriers of organic contaminants in aqueous solutions. DZN is a non-systemic organophosphorus pesticide that poses risks human and environmental health. This study aimed investigate the adsorption onto PE by examining factors such dose, reaction time, concentration, pH through experimental runs based on Box‒Behnken model. According Langmuir model, maximum capacity for was 0.35 mg/g. The results indicated highest rate (92%) observed distilled water, while lowest (57%) municipal wastewater. Δ H ° S values were obtained − 0.16 kJ/mol 54.41 J/(mol K), respectively. Therefore, regarding negative G values, it can be concluded an exothermic, highly disordered, spontaneous process. findings indicate reduction concentrations interfering compounds increase. These offer understanding interaction between contaminants, emphasizing need further studies approaches reduce harmful impact health environment.
