“…The most prominent form of zinc available in industrial effluent is zinc ions (Mishra and Patel 2009). According to the list of organic and inorganic pollutants prepared by United States Environmental Protection Agency (USEP-A), zinc has been kept in the list of toxic metals with other 13 metals (Kumar et al 2006;Cesur and Balkaya 2007).…”

Massive industrialization and urbanization of civilization during the last few decades have made a thrust in heavy metal pollution in various water bodies. In past, various kinds of conventional metal ion remediation technologies, such as cementation, osmosis, reverse osmosis, ultrafiltration, etc., have been practised. However, most of these technologies are quite expensive, and lead to the generation of secondary chemical sludge. However, biosorption of heavy metal ions is significantly inexpensive and an eco-friendly technology. Among the series of heavy metals, zinc has gained the significant interest due to its toxicity and easy availability in water bodies. Biosorption of zinc in liquid phase by living, nonliving, conventional and non-conventional biosorbents has been practised extensively in the past. This literature review focuses on the recent trends practised in the field of biosorption of zinc from liquid phase. The present work provides deep insight into various aspects of biosorption of zinc by different mechanisms of biosorption, bioaccumulation, isotherm, kinetic and mechanistic modeling. An exhaustive comparison among different sorts of biomasses has also been given in the present work to enlist all the milestones of biosorption.

The valorization of domestic wastes becomes a very important research axis that can reduce the energy consumption and protect our environment. The objective of this study is to remove zinc ions from wastewater by using banana peels after their activation as sensor in the working electrode for an environmental application. Banana peels were dried, crushed and treated with sulfuric acid then mixed with polyaniline to improve their electrical conductivity. Cyclic voltammetry and chronoamperometry were used for electrochemistry tests. The obtained voltammogramms at well optimized conditions of applied potential of -1.3 V/SCE and initial zinc concentration of 0.2M during 2 hours of electrolysis, showed the reduction peak of the zinc at a potential of -1.14 V/SCE, which confirmed the activity of this electrode. The modeling of experimental data revealed that the adsorption was fitted by the Langmuir isotherm with a maximal adsorption capacity of 3.4188 mg/g. Changes in the structure of the powder after the electrosorption was noticed by SEM and EDX. Finally, the dosage of the electrolytic solution showed a diminution of the zinc concentration with yield of 99.99%.
