In this study, cadmium selenide quantum dots (CdSe-QD) were synthesized and characterized. Dye removal ability of CdSe-QD with UV irradiation (UV/CdSe-QD) was investigated. The synthesized QD was characterized by X-ray diffraction, transmittance electron microscope, Fourier transformation infrared, dynamic light scattering, atomic force microscopy, UV–visible, and photoluminescence analyses. Basic Violet 16, Basic Blue 41, and Acid Blue 92 were used as model dyes. The effect of CdSe-QD dosage on dye removal in presence of UV irradiation was studied. The obtained results showed that dye removal followed by a first-order kinetic model. It has been found that CdSe-QD has dye removal ability from colored wastewater in the presence of UV irradiation.
