Removal of Mercury (II) by Adsorption in Aqueous Solutions with Pomegranate Husks

Abstract

This article shows the analysis of the efficiency of the pomegranate husks like an adsorbent agent in aqueous solutions contaminate with mercury (II). The contaminated with mercury (II). The variables of this experiment were: the initial concentration of mercury (II) in water, quantity of adsorbent material 50 ml of contaminate solution with Hg (2 and 4 grams), size of the particle of pomegranate husk and contact time between adsorbate and adsorbent (60 minutes). In this process the pomegranate husks were dehydrated at temperature between 30 °C and 50 °C. The results obtained at the end of the investigation show that the pomegranate husks have the capacity to decontaminate mercury (II) from contaminated water at a level of 1 ppm quantity accepted by the World Health Organization (WHO, 2003). This is an alternative method, environmentally friendly and sustainable to eliminate pollutant agents from water such as mercury (II).
