Synthesis and characterization of zinc oxide nanoparticles: It’s application for the removal of alizarin red S dye

Abstract

The zinc oxide nanoparticles were incorporated and applied for the removal of alizarin red S color from the hydrous solution. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy were utilized to investigate the synthesized ZnO NPs. The adsorption cycle was explored in batch mode at 303 K temperature, with changing the variables, for example, agitation time, weight dosage, pH, and dye concentration initially being differed. At the point when the agitation time was 35 min, the adsorbent measurements was 0.4 g/L, the pH was 4, and the dye concentration initially was 10 mg/L, the adsorption strategy for eliminating ARS not entirely set in stone to be generally proficient. A pseudo - first - order dynamic model and the Langmuir isotherm suit the exploratory information pleasantly. The greatest adsorption limit, as indicated by the test results, is 123.3 mg/g, which is near the determined qe of 127.6 mg/g.
