Effective removal of heavy metal: mercury concentration using natural adsorbents

Industrial effluent is not always safe to the environment because of the presence of huge amounts of substantial heavy metals like arsenic, cadmium, chromium, nickel, mercury, etc. If the wastewater is disposed of in the environment without any prior treatment, it will result in environmental pollut...

Description
Summary:Industrial effluent is not always safe to the environment because of the presence of huge amounts of substantial heavy metals like arsenic, cadmium, chromium, nickel, mercury, etc. If the wastewater is disposed of in the environment without any prior treatment, it will result in environmental pollution that would affect water bodies, soil strata, and all other natural resources. This research focuses on the removal process of identified toxic heavy metals, i.e., mercury from effluent, using natural adsorbents like Ground Gulmohar seeds and Waste Tea powder. The performance of these adsorbents was compared with the removal efficiency of conventionally used material, i.e. Powdered Activated Carbon. Experimental parameters such as pH, contact time, adsorbent dosage, and initial concentration were taken into consideration to calculate the removal efficiency, and the accuracy of the results was interpreted with adsorption isotherm models. The findings of this research demonstrate that the natural adsorbents Waste Tea powder & Ground Gulmohar seeds have high efficiency in the removal of mercury metal concentration from prepared aqueous solution.
