In my thesis, I studied the effect of light intensity on the photocatalytic efficiency of titanium dioxide (TiO$_2$) for the degradation of the dye Plasmocorinth B. Photocatalysis is a promising method for environmental remediation, as it enables the degradation of pollutants in the presence of a photocatalyst and light. The experimental part involved the preparation of TiO$_2$ as a photocatalyst and the preparation of a dye solution, which was subjected to the photocatalytic process under different light intensities achieved by adjusting the number of lamps used. The efficiency of dye degradation was monitored through absorbance measurements using a UV-Vis spectrophotometer and total organic carbon (TOC) analysis. The results showed that higher light intensity leads to faster and more efficient dye degradation and mineralization of the organic material. These findings confirm that light intensity is a key factor in the optimization of photocatalytic processes.
