Influence of biochar on the removal of Microcystin-LR and Saxitoxin from aqueous solutions

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Май 14, 2024

The present study assessed the effective use of biochar for adsorption two potent HAB toxins namely, Microcystin-LR (MCLR) and Saxitoxin (STX) through a combination dosage, kinetic, equilibrium, initial pH, competitive experiments. results suggest that has excellent capabilities removing MCLR STX, with STX reporting higher capacities (622.53-3507.46 µg/g). removal required minimal dosage 0.02 g/L, while needed 0.4 g/L > 90%. Similarly, shorter contact time was compared to 90% toxin removed from water. Initial pH revealed acidic conditions favored uptake basic conditions. Kinetic studies Elovich model be most suitable both toxins, also showed fittings Pseudo-First Order Pseudo-Second in individual systems. suited kinetic presence each other. Isotherm confirmed Langmuir-Freundlich as best fit toxins. These mechanisms including pore filling, hydrogen bonding, π-π interactions, hydrophobic electrostatic attraction, dispersive interactions.

Synergy of Free Radicals in Microcystis aeruginosa Inactivation within an Electrolysis/Persulfate/Chlorine System

ACS ES&T Water, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 8, 2024

In this study, an electrochemical system combined with peroxymonosulfate (PMS) and chlorine was developed to enhance the removal efficiency of Microcystis aeruginosa. The almost complete inactivation algal cells can be achieved in 30 min at a concentration 30.0 μM, PMS 0.75 mM, current density 15 mA/cm2. Quenching experiments indicate involvement •OH, SO4•–, Cl•, •O2–, 1O2 M. aeruginosa, SO4•– plays crucial role. Besides inherent contribution fortifying electrolysis/PMS/chlorine system, ability control proliferation is also bolstered by indirect activation species. alterations superoxide dismutase, CAT, malondialdehyde activities substantiate induction apoptosis cells. production free radicals precipitates cascade oxidative impairment within cells, which characterized marked transformations cell morphology structural integrity. Further, microcystin-LR actual water body could effectively removed system. findings study convincingly establish as efficient environmentally friendly application alga wastewater treatment.
