CWE/1949/2021 当前世界环境 0973-4929 2320-8031 Enviro Research Publishers CWE--81-00 Adsorptive Studies for the Removal of Crystal Violet Dye from Aqueous Solution by Using Cicca Acida L. Stem - Activated Carbon 10.12944/CWE.16.2.10 Volume 16 Volume 16 436 - 443 Abstract

Textile industries discharge wastewater containing various dyes including Crystal Violet dye. These dyes are very harmful for human beings, animals and plants. Therefore, the attempt is made for adsorption framework on elimination of crystal violet dye by using Cicca acida L. stem-activated carbon from aqueous solution carried out under various experimental methods and optimization conditions.  Adsorption data modeled with Freundlich, Langmuir and Tempkin adsorption isotherms. Thermodynamic factors like as ∆Ho, ∆So and ∆Go were calculated, which indicated that the adsorption was spontaneous and endothermic nature. Based on kinetic study, pseudo-second order kinetic model was fit compared to the pseudo-first order kinetic model. The adsorbent has been characterized by SEM before and after adsorption of crystal violet dye solution.
