Investigating Effective Parameters on the Removal Mercury Ion from Aqueous Phase by Adsorption Using Carbonaceous Sorbents

Nowadays, better life is provided for human being by means of new knowledge and technology, but on the other hand, the environment is periled by their consequences. One of the pollution menace the environmental life of human and other creatures is the presence of mercury ion in aqueous streams. In the present article, adsorption of this poisonous material and effective operating parameters such as: temperature, pH, initial concentration and impregnating materials are thoroughly investigated. One of the efficient methods for removing mercury ion from liquid and gas phases is adsorption technique using porous solids. Among them, carbonaceous sorbents perform a prominent roll. In this regards, effective parameters in the adsorption of mercury from aqueous solutions using carbonaceous sorbent are explained in the present paper. Among different factors, smaller particle size of adsorbent, degree of microporosity, higher pH, and higher initial Hg concentration, would increase the adsorption amount of mercury from the liquid phase.
