Investigative Study of Crystal Violet Photo-Degradation in The Presence of Lead Chromate

Abstract

This study addresses the environmental challenges posed by wastewater from dye factories, focusing on Crystal Violet, a dye with severe genotoxic effects. It highlights the photocatalytic efficiency of lead chromate, synthesized via direct co-precipitation, for degrading organic pollutants under visible light. FT-IR and UV-Visible spectroscopy confirmed its structural and optical properties. Key parameters like pH, dye concentration, semiconductor dosage, and light intensity were optimized, and a potential photodegradation mechanism for Crystal Violet was proposed.
