Abstract
The influence of the concentration of Na+, Cl-, HCO3- ions on the efficiency of photocatalytic destruction of model organic dyes is considered: cationic - methylene blue (MB); anionic - methyl orange (MO). Using monthly monitoring of hydrochemical parameters of polluted rivers of urbanized areas (Khabarovsk, Russia) during 2023, it is shown that the concentration of ions varies in the ranges: 10–450 mg/l for HCO3-; 13–180 mg/l for Na+; 1–360 mg/l for Cl-. The kinetics of photodestruction of model pollutants was studied at concentrations of the studied ions of 0, 1, 10, 100, 1000, 10000 mg/l (for crystalline substance) using the reference photocatalyst titanium dioxide (P25). The photodestruction time (t) was estimated at different values of the conversion degree (α) of model pollutants at: initial – 10%t; middle – 50%t; final – 90%t stages of the photocatalytic process. The pseudo-first-order reaction rate constants were calculated on the linear section of the kinetic curves. The effect of the concentration of Na+, Cl-, HCO3- ions on the degree of titanium dioxide dispersion was studied based on the turbidity values of the photocatalytic solution at the dark stage.
Supporting agencies: The work was carried out within the framework of the state assignment of the Institute of Information and Geophysics of the Far Eastern Branch of the Russian Academy of Sciences.
