Description
Currently, the global community is confronting water contamination from several sources, which poses significant environmental challenges. The reutilisation of polluted water constitutes a feasible strategy for sustainable wastewater management. In the present study, Mn3O4 was synthesised via chemical precipitation using polyvinyl alcohol (PVA), cetyltrimethylammonium bromide (CTAB) and glycine as surfactants and without any surfactants. The synthesised Mn3O4 using Glycine(MNG) showed the best photocatalytic efficacy compared to other synthesised materials, about 93 0.35% disintegration of Rhodamine B in 150min when illuminated with visible light. The progress of photodegradation was in conformity with the pseudo-first-order kinetic model with a velocity of 0.017min?1. Photoelectrochemical investigations assessed charge transfer, stability, and light-harvesting behaviour of Mn3O4 catalysts, showing their improved performance beyond photocatalysis. Seed germination in the treated water, controlled and uncontrolled conditions, was compared to ensure the agricultural and environmental viability. Additionally, ~ 84.54% of total organic carbon removal was achieved. A conceivable degradation mechanism was suggested after the degraded intermediates were examined using high-performance liquid chromatography (HPLC) and the elution patterns and retention periods.
