[ 1 ] - Evaluation of adsorption efficiency of activated carbon/chitosan composite for removal of Cr (VI) and Cd (II) from single and bi-solute dilute solution
The aim of this study was to evaluate the adsorption capacity of the novel coated activated carbon by chitosan for removal of Cr (VI) and Cd (II) ions from single and bi-solute dilute aqueous solutions. In addition, the adsorption abilities of activated carbon (AC), chitosan (CH) and chitosan / activated carbon composite (CHAC) have been compared. Adsorption studies were performed in a batch sy...
[ 2 ] - Statistical physics modeling of equilibrium adsorption of cadmium ions onto activated carbon, chitosan and chitosan/activated carbon composite
The adsorption ability of activated carbon, chitosan, and chitosan/activated carbon composite for cadmium separation from aqueous solution was analyzed via statistical physical modeling. The equilibrium data were analyzed by Langmuir, Hill, double layer model, and the multi-layer model with saturation isotherm models. Results showed that the multi-layer model with saturation could well describe...
[ 3 ] - Xylene removal from dilute solution by palm kernel activated charcoal: Kinetics and equilibrium analysis
Xylene is an aromatic hydrocarbon that is a highly toxic compound. Therefore, it is essential to remove this component from wastewater before discharging it to the environment. In this research work, palm kernel biomass was activated chemically by H3PO4 and synthesized activated charcoal was applied to separate xylene from aqueous media. The prepared activated charcoal was characterized using F...
[ 4 ] - Cadmium removal from wastewater using nano-clay/TiO2 composite: kinetics, equilibrium and thermodynamic study
In this research, commercial nano-clay (NC) was modified with TiO2 functional groups and characterized via XRD and FTIR methods. The modified nano-clay was applied as an adsorbent for the removal of cadmium from wastewater solutions. The effects of the operating parameters including initial pH, cadmium concentration and adsorbent concentration were analyzed by the Taguchi method. The...
