Supplementary material for the research paper titled " Congo red dye removal using green synthesized titanium oxide nanoparticles using saponin biosurfactant derived from Sapindus mukorossi"

The data presents the Congo Red dye removal efficiency using synthesized biogenic TiO₂ nanoparticles derived from saponin biosurfactant of Sapindus mukorossi. The study investigates the effect of varying adsorbent dosages (1, 2, 2.5, and 5 g/L) and different initial dye concentrations ranging from 50 ppm to 150 ppm. The experiments were designed to evaluate the adsorption capacity and efficiency of biogenic TiO₂ under these varying conditions. The results are compiled and presented in tabulated form.
