Adsorption

In this study, two activated carbons were prepared from loofa, loofa carbon-1 (LC1) and loofa carbon-2 (LC2). The surface structure of LC1 and LC2 were analyzed by scanning electronic microscopy (SEM). The ability of LC1 and LC2 to remove reactive orange (RO) dye from aqueous solutions by adsorption

Treatment of aniline hypersaline wastewater with a combined physical–biological method was investigated in this study. This method consisted of the physical adsorption of aniline from hypersaline effluents by resins and the biodegradation of the adsorbate and the regeneration of the adsorbent in the

The batch removal of Fe3+ from aqueous model solution under different experimental conditions using Jordanian natural zeolite (JNZ) has been investigated. The influences of contact time, metal initial concentration, adsorbent dosage concentration, and temperature have been studied. The adsorption ef

The potentialities of castor seed shell (CSS), a waste agricultural by-product, in the remediation of water, contaminated with Methylene Blue (MB), a basic dye, were investigated in the present study. The CSS was ground and washed, thoroughly, to remove any water extractable constituents. The dried

The occurrence of arsenic in natural ground waters is due to geological composition of soil. There are several methods for removal of arsenic from drinking water, such as coagulation followed by filtration, membrane processes, ion exchange and adsorption. Adsorption methods proved to be effective, e

Bamboo, indigenous to Hong Kong and China, is widely used as scaffolding in construction and building projects. However, over 50,000 tonnes of bamboo scaffolding waste is disposed as landfill waste each year. Nevertheless, these wastes can be used as raw materials for the production of a range of hi

Recovery of nickel and cobalt from organic acid complexes generated by bioleaching of nickel laterite ores with heterotrophic organism and their metabolites were conducted by ion-exchange. This study investigated specifically the adsorption of nickel and cobalt complexed with citrate, malate and lac

In this study, experiments were carried out to estimate sorptivity of chitosan beads and their selectivity towards Cu2+ (copper sulfate), Zn2+ (zinc sulfate) and Cr6+ (potassium dichromate) ions. Studies were performed in the concentration range from 20 to 500 mg/dm3 for single ions and their binary

Activated carbon was developed from coconut coir pith using ZnCl2 and investigated to assess the possible use of this adsorbent for the removal of sulfate from water. The influence of various parameters such as agitation time, sulfate concentration, adsorbent dose, pH and temperature has been studie

Diatomite, an abundant inorganic material in Jordan, was treated with sulfuric acid and heat treated in order to improve its performance as an adsorbent. The acid treated diatomite (ATD) was used to adsorb methylene blue from aqueous solutions. The equilibrium data were fitted to different adsorptio
