Preparation and characterization of activated carbon from sugarcane bagasse by physical activation with CO2 gas
A series of experiments have been conducted to study the effects of different carbonization temperatures (400, 600, and 800oC) on characteristics of porosity in activated carbon derived from carbonized sugarcane bagassechar at activation temperature of 800oC. The results showed that the activated carbon derived from high carbonized temperature of sugarcane bagassechars had higher BET surface ar...
متن کاملOptimization of Tea Waste Activated Carbon Preparation Parameters for Removal of Cibacron Yellow Dye from Textile Waste Waters
Waste from tea, a beverage globally consumed is a common menace discarded to the environment thereby contributing to environmental pollution. The textile and paper industries have also been major culprits in the pollution of the environment through their indiscriminate discharge of dye solutions. These dyes are carcinogenic, mutagenic, and generally harmful to the entire eco-system; this has po...
متن کاملPreparation, Surface and Pore Structure of High Surface Area Activated Carbon Fibers from Bamboo by Steam Activation
High surface area activated carbon fibers (ACF) have been prepared from bamboo by steam activation after liquefaction and curing. The influences of activation temperature on the microstructure, surface area and porosity were investigated. The results showed that ACF from bamboo at 850 °C have the maximum iodine and methylene blue adsorption values. Aside from the graphitic carbon, phenolic and ...
متن کاملEfficiency of Activated Carbon Produced by Physical Activation Using Nitrogen Gas for Maximum Dye Adsorption from Polluted Effluents: Genetic Programming and Neural Network
Background and purpose: This study was conducted for the first time to produce activated carbon (AC) from Milkvetch wood by physical activation in order to achieve the maximum adsorbent capacity in adsorption of dye. The aim of this study was to remove acid orange 7 (AO7) dye using AC produced by physical activation with nitrogen gas. Materials and methods: AC activation was performed by physi...
متن کاملComparative potential of black tea leaves waste to granular activated carbon in adsorption of endocrine disrupting compounds from aqueous solution
The adsorption properties and mechanics of selected endocrine disrupting compounds; 17 β-estradiol, 17 α – ethinylestradiol and bisphenol A on locally available black tea leaves waste and granular activated carbon were investigated. The results obtained indicated that the kinetics of adsorption were pH, adsorbent dose, contact time and temperature dependent with equilibrium being reached at 20 ...
