Kinetic modeling of methylene blue adsorption onto acid-activated spent tea: A comparison between linear and non-linear regression analysis
The kinetic study of methylene blue (MB) adsorption using acid-activated spent tea (AAST) as an adsorbent from aqueous solution with the aim of comparing linear and non-linear regression analysis methods was performed at varying initial MB concentrations (10-100 mg/l). Hence, spent tea leaves, which were activated using concentrated sulfuric acid, were prepared. The physicochemical characterist...
متن کاملDevelopment of sustainable dye adsorption system using nutraceutical industrial fennel seed spent-studies using Congo red dye.
Fennel seed spent (FSS)-an inexpensive nutraceutical industrial spent has been used as an efficient biosorbent for the removal of Congo red (CR) from aqueous media. Results show that the conditions for maximum adsorption would be pH 2-4 and 30°C were ideal for maximum adsorption. Based on regression fitting of the data, it was determined that the Sips isotherm (R2 = 0.994, χ2 = 0.5) adequately ...
متن کاملOptimization of Acid Blue 113 Adsorption from Aqueous Solutions by Natural Bentonite Using Response Surface Model: Isotherm and Kinetic Study
Background & objectives: Dyes are one of the main environmental pollutants of textile industrial wastewater which are toxic, carcinogenic, mutagenic, and non-biodegradable. Therefore, in this study, Response Surface Methodology (RSM) was used to investigate the operational parameters and determine the optimum conditions for the removal of acid blue 113 in the presence of bentonite. Methods: The...
متن کاملEquilibrium Modeling and Kinetic Studies on the Adsorption of Basic Dye by a Low Cost Adsorbent
An agricultural waste and eco-friendly biosorbent i.e. rice husk has been used as a cheap adsorbentfor the removal of methylene blue dye from aqueous solutions. The physical properties of the developedadsorbent were characterized using FTIR. The study was realized using batch experiments. The effectsof contact time, pH, initial dye concentration, biosorbent dose and temperature were investigate...
متن کاملStudy Kinetic and Isotherm adsorption of Reactive Blue 39 onto nano Zinc hydroxide chloride
Zinc hydroxide chloride nanostructure was successfully synthesized through a simple method at low temperature by sonochemical process. The morphology and crystalline of the products were analyzed by XRD, FESEM and TEM. The effect of independent variables including contact time, solution pH, adsorbent dosage and the concentration of dyes on response performance with response to surface methodolo...
