Natural Adsorbent and Dyes 12+

🔖 The dust of woody plants Malus domestica and Prunus persica was activated by chemicals means. The surface was characterized by BET surface area, FTIR, Scanning electron micrograph, Energy dispersive spectroscopy analysis. Adsorption of some basic dyes on each sample was studied by kinetics and batch adsorption techniques at different adsorption temperatures. The residual concentration of the dye was determined by using UV-vis spectrophotometric technique. The removal of dyes from wastewater was studied with respect to initial dye concentrations, equilibration time and different dye concentration for batch studies. Adsorption kinetics was analyzed by using intraparticle diffusion, Elovich and Bangham models. For batch study Langmuir, Freundlich, Tempkin and Harkins-Jura linear equations were used for analyzing the data and were found fit to the adsorption data.
