“…An experiment conducted by Mansoorian et al showed that electrocoagulation can effectively reduce high amounts of metal ions with hydroxide iron and steel flocs as absorbents. In this study, an electrochemical cell with thirty iron and stainless steel rods with 50 mm length and 5 mm diameter was used.…”

Heavy metals like arsenic, copper, cadmium, chromium, nickel, zinc, lead, and mercury are major pollutants of fresh water reservoirs because of their toxic, non‐biodegradable, and persistent nature. The industrial growth is the major source of heavy metals introducing such pollutants into different segments of the environment including air, water, soil, and biosphere. Heavy metals are easily absorbed by fishes and vegetables due to their high solubility in the aquatic environments. Hence, they may accumulate in the human body by means of the food chain. Various methods have been developed and used for water and wastewater treatment to decrease heavy metal concentrations. These technologies include membrane filtration, ion‐exchange, adsorption, chemical precipitation, nanotechnology treatments, electrochemical and advanced oxidation processes. In this review, the methods as well as their mechanisms and efficiency are discussed.

“…Contamination and pollution caused due to the presence of heavy metals has received keen attention because of their detrimental toxic effects on the human health and biotic organisms [1]. Effluents of industrial wastewaters consist of many toxic heavy metals ions such as lead, mercury, chromium, nickel, cadmium, and zinc ions which lead to severe toxic effects on soil as well as aquatic ecosystem [2]. One of the most venomous heavy metals reported was lead ion which was present in the environment in micro level; nowadays it is reported as the major noxious pollutant present in the aquatic ecosystem.…”

2015): Removal of Pb(II) ion from aqueous solution by graphene oxide and functionalized graphene oxide-thiol: effect of cysteamine concentration on the bonding constant, Desalination and Water Treatment, A B S T R A C TEfficient adsorbent graphene oxide (GO) and its derivative, i.e., thiol-functionalized graphene oxide (GO-SH), was used for the removal of noxious Pb(II) ion from the aqueous phase. Different amounts, i.e., 60, 80, and 100 mg of cysteamine, were used as functionalizing agent to functionalize the GO with thiol group; hence, three different nanocomposites, i.e., GO-SH 1 , GO-SH 2 , and GO-SH 3 were prepared from the different amount of the cysteamine. The developed nanocomposites were characterized using various analytical techniques such as Fourier transform infrared spectroscopy, scanning electron microscopy, and X-ray diffraction analysis. The whole removal and adsorption process was well illustrated and investigated. The impact of influential factors including initial concentration, pH, contact time, temperature, and concentrations cysteamine on the adsorption properties of Pb(II) from aqueous solution was well elucidated and optimized. The obtained equilibrium results were inserted in various adsorption isotherm models such as Langmuir (liner types I, II, III, and IV), Freundlich, Temkin, Helsey, and Dubinin-Radushkevich isotherms, it was found that the Langmuir (type I) model demonstrated was well fitted and in good agreement with the maximum adsorption of Pb(II) ion from aqueous solution. Thermodynamic functions, such as ΔG˚, ΔH˚, and ΔSẘ ere calculated and it reveals that the adsorption of Pb(II) ion on all the surfaces was spontaneous and endothermic in nature.

Electro-coagulation analytical technique has been used for the removal of malachite green -a dyestuff used as antimicrobial in aquaculture. Effects of parameters such as current density, pH, dye initial concentration, interelectrode separation and amount of electrolyte on the dye color-removal have been investigated using Al and Fe as scarifying anodes. It was observed that whereas increase in dye initial concentration or inter-electrode separation, the rate of color removal continuously falls, however, on raising of electrolyte concentration, color removal rate enhances up to a definite electrolyte level, beyond that there was no further improvement in the color removal. Further, for achieving maximum color removal of malachite green aqueous solution optimum current density (76.5A/m 2 ) and pH (8.0) of solution, is required. Complete color removal of 100mg/L malachite green aqueous solution could be achieved in 30min using electrolyte (NaCl) concentration 0.4g/L, inter-electrode distance: 1cm and optimum pH and current density. Performance of Al and Fe as sacrificial electrodes, in terms of their color removal efficiency, was almost similar except in their response to inter-electrode separation, as variable, where in case of Fe as anode, color removal rate declined more rapidly. The outcome of the present research work may be useful for an effective large scale treatment of industrial effluents contaminated with malachite green dye. Keywords:
