A local clay from Jebel Chakir (northwest of Tunis, Tunisia, North Africa) has been characterized. The mineralogical and chemical compositions of the materials were determined by X-ray diffraction (XRD), infrared spectroscopy (IR) and by the inductively coupled plasma technique (ICP). The cation exc

Adsorption behavior of molybdate and tungstate from water by acid-treated carbon cloth was investigated. The carbon cloth was treated with sulfuric acid and used for the adsorption of molybdate and tungstate from water samples at nearly neutral solutions. The concentration of ions in the solution wa

Adsorption techniques are widely used to remove certain classes of pollutants from waters, especially those that are not easily biodegradable. Dyes represent one of the problematic groups. Natural zeolite was used as a low-cost adsorbent to evaluate its ability to remove color from effluents. In thi

The leaf sheath fibres of the Mediterranean seagrass Posidonia oceanica (L.) were used as low cost, available and renewable biological adsorbent for the removal of a metal complex textile dye from aqueous solutions. Batch experiments were carried out for sorption kinetics and isotherms. Operating va

The objective of this study was to investigate the removal of phenol from aqueous solution by using acid activated red mud in batch adsorption experiments. The study was carried out as functions of pH, contact time, activated red mud dosage and initial phenol concentration. It was found that the max

The use of low-cost and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. Orange peel was collected from the local fields of orange trees and converted into a low-cost adsorbent. The present study deals with the r

Mono- and pentamine immobilized silica were prepared through the treatment of silica with 3-aminopropyltriethoxysilane and 3-glycidoxypropyltrimethoxysialne. The success of immobilization process was confirmed by means of FT-IR and thermogravimetry (TG). The surface properties of the modified silica

Adsorbent prepared from maize cob powder (MCP), an agricultural waste, was successfully used to remove the malachite green from an aqueous solution. The adsorption was carried out by varying the parameters such as agitation time, dye concentration, adsorbent dose and pH at constant temperature of 27
