Removal of Lead from Industrial Wastewater Using Flow-by-Porous Electrode

Abstract

Lead present in several industrial wastes has deleterious effects on the quality of water. Cathodic deposition has been considered as one of the suitable means for lead removal. Experiments were carried out using a lab-scale electrochemical cell incorporating flowby porous graphite electrodes at steady state conditions. The effects of flow rate, current density, lead influent concentration and pH, on lead removal efficiency, current efficiency, lead removal rates, and cell potential, were investigated. It was found that the maximum removal efficiency (97.75%) was obtained at flow rate (100 mL/min), for initial concentration (40 mg/L), with a residual concentration (0.9 mg/L) and maximum current efficiency of (60.7%). In addition, the recovery of lead from wastewater was investigated.

Recycling of Steel Industry Waste Acid in the Preparation of Fe3O4 Nanocomposite for Heavy Metals Remediation from Wastewater

“…Nano-sized magnetic polymer adsorbent combined with tetraethylene-pentamine (TEPA-NMP) was developed for batch adsorption of Cr(VI) [24]. While Fe/Cu bimetallic adsorbent introduced as a novel industrial wastewater pre-management [25] and co-precipitation techniques [26] used for the elimination of Ni(II), Cr(VI), Cd(II), Mn(II), Pb(II), and Zn(II) with the aid of Cu(II) cyclohexyl methyl dithiocarbamate [27,28]. Natural polymers are preferred in modifying the nanoparticles surface to avoid cytotoxicity.…”
