Abstract: This work examines the adsorption of Ni(II) onto sludge–ash, a waste produced from a fluidized bed incinerator combusted primarily with biosolids. Results of kinetic experiments showed that the adsorption was rapid. The ...

Abstract: The present study investigates the adsorption characteristics of Cu(II) onto a low-cost biosorbent, pineapple leaf powder (PLP). Results of batch adsorption experiments showed that PLP could effectively remove Cu(II) from ...

Abstract: The effectiveness of the electrokinetic (EK) process in treating soil enriched in chromite ore processing residue (Cr–soil) was investigated. An electric gradient of 1.2 V/cm was applied to induce the movement of electrolyte ...

Abstract: Brick manufactured from incinerated sewage sludge ash and clay is investigated. The results of Atterberg limits tests of molded ash-clay mixtures indicated that both plastic index and dry shrinkage decrease with an increasing ...

Abstract: Some paddy rice fields in central Taiwan had been exposed for more than 20 years to irrigation water containing metal. This study was carried out to evaluate the spatial distribution of heavy metal in soils exemplified by ...

Abstract: Chromium leaching experiments were conducted using soils rich in chromite ore processing residue (COPR). Experiments were performed with acrylic columns under a constant hydraulic head and a free board. Air was purged ...

Abstract: The performance of a series-electrokinetic (EK) process in treating a clay soil artificially contaminated with 300 mg/kg trichloroethylene (TCE) was investigated. Constant voltage gradients of 1 or 2 V/cm to induce the ...

Abstract: Removal of Cr(VI) from aqueous solutions has been investigated by adsorption on a low-cost adsorbent, calcined rice husk (CRH). Rice husk is an agrowaste material. It was thermally treated in a muffle furnace at 650°C for ...

Abstract: Adsorption of Cr(VI) onto hydrous concrete particles in synthetic groundwater was investigated with batch equilibrium adsorption experiments. Results show marked adsorption under acidic conditions, and the amount of Cr(VI) ...

Abstract: The effectiveness of incorporating Fe(O) barrier into electrokinetic (EK) process to remediate Cr(VI) contaminated clay
