摘要：

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.
