Removal of 4-Chlorophenol from Contaminated Water Using Activated Carbon from Dried Date Pits: Equilibrium, Kinetics, and Thermodynamics Analyses
Five different activated carbons (ACs) have been prepared from dried date pits using air and phosphoric acid as activating agents. The used phosphoric acid:date pit ratio dictated the characteristics of the prepared ACs; the equivalent BET-nitrogen surface area varied from 794 m²/g for a ratio of 5:1, to 1707 m²/g for a ratio of 2:1, whereas the micropore volume changed in value from 0.24 cm³/g...
متن کاملFast Removal of Malachite Green by Adsorption on Rice Husk Activated Carbon
Application of activated carbon developed from rice husk, an agricultural waste product has been investigated for the removal of malachite green from aqueous solutions and wastewaters. Batch adsorption experiments were carried out for the removal of malachite green from aqueous solutions onto rice husk activated carbon. Effect of important parameters namely initial concentration of dye and cont...
متن کاملMalachite green dye, removal from waste water by adsorption
The organic dyes directly pollute the soil, water, plants and all living systems in the environment. In the present investigation, adsorption of brilliant green dye on silica from aqueous solution was studied. The dye adsorption mechanism was studied on the basic surface of silica. The adsorption parameters were optimized to maximum adsorption. The adsorption mechanism of brilliant green on sil...
متن کاملAdsorption of Malachite Green from Aqueous Solution using Activated Ntezi Clay: Optimization, Isotherm and Kinetic Studies
The adsorption of malachite green from aqueous solution using a local low cost adsorbent, acid activated Ntezi clay, was investigated. The low cost adsorbent was activated with different concentrations of sulphuric acid and the physicochemical properties of the adsorbent were determined and the structural properties were analyzed using XRF and XRD. The adsorption process was studied as a functi...
متن کاملPhotocatalytic Removal of Malachite Green Dye from Aqueous Solutions Using Halloysite–TiO2 Nanocomposite
Background and purpose: Malachite green is one of the most widely used dyes in various industries, aquaculture, and fungicides. The residues have adverse effects on environmental and human health and should be removed from the effluent before discharging to the environment. The purpose of this study was to investigate the efficiency of photocatalytic process using halloysite-titanium dioxide n...
