ABSTRACT / САЖЕТАК:
Dye-containing wastewater represents a serious environmental problem due to the toxicity and persistence of synthetic dyes. In this study, the catalytic activity of silver nanoparticles (AgNPs) obtained by green synthesis using Agrimonia eupatoria L. plant extract as a reducing agent was investigated. The catalytic performance of AgNPs was evaluated through the reduction of Congo red in the presence of NaBH₄, monitored by UV–Vis spectrophotometry. The results demonstrated efficient catalytic degradation of the dye, with a calculated pseudo-first-order rate constant of k′ = 0.0299 min⁻1. The biogenic AgNPs exhibited high catalytic efficiency, indicating their strong potential for application in wastewater treatment.
