“…The effective treatment of heavy metals from industrial effluent has been one of the major issues due to their toxicities. Among all conventional treatment methods, heavy metals can be removed by chemical precipitation,1 ion exchange resins,2 and adsorption 3. Recently, chelate membranes have been applied for the adsorption of specific metal ions from industrial wastes.…”

A new chelate membrane was prepared by grafting of glycidyl methacrylate (GMA) onto high-density polyethylene membranes and subsequent amination of poly-GMA graft chains. The effects of grafting conditions such as radiation dose and temperature on grafting yield were studied. Effects of various parameters such as grafting yield, pH, and adsorption time on the metal uptake were investigated. The results show that the maximum metal uptake followed as given in the order Cr (III)>Fe (III)>Cu (II)>Cd (II). The metal uptake increased with grafting yield, adsorption time, pH of the medium, and initial concentration. The chelated metal ions are easily desorbed with 0.1 mol/L hydrochloric acid at room temperature. The results obtained from the chelate membrane showed a promising application in extraction of heavy metal ions from industrial effluents.

“…Because heavy metals are generally toxic and non-biodegradable, they can be accumulated in living organisms and pose a risk to the ecosystem and human health. At present time, there are many conventional methods for removing heavy metals from industrial wastewater, including chemical precipitation (Lin et al 2005), oxidation-reduction (Chang 2005), ion exchange (Eom et al 2005), adsorption (Mohan & Chander 2006), membrane filtration (Zhong et al 2007) and electrolytic methods (Feng et al 2007). However, these methods have the limitations of their low efficiency, high operational cost and sludge generation (Chen & Wang 2008).…”

Because of having a high reduction potential, the zero-valent iron (ZVI) is often applied for the remediation of wastewater or groundwater with heavy metals. The purpose of this study was aimed to investigate the reaction behavior of heavy metals with ZVI nanoparticles in the wastewater. The affecting factors, such as initial pH, dosage of nanoscale ZVI and initial concentration of heavy metal, on the removal efficiency of heavy metals by ZVI in the wastewater were examined by the batch experiments in this study. It was found that the removal of heavy metals was affected by initial pH. The rate and efficiency of metal removal increased with decreasing initial pH. Greater than 90% of the heavy metals were removed when the initial pH was controlled at 2. In addition, the rate and efficiency of metal removal increased as the dosage of nanoscale ZVI increased. The removal efficiency of heavy metal was higher than 80% when 2.0 g/L of ZVI was added in the wastewater. On the other hand, the slow rate and low efficiency of metal removal from the wastewater treated by nanoscale ZVI was found in the wastewater with high concentration of heavy metal.
