Removal of Mercury from Aqueous Solutions by Waste Brick
Journal Title: International Journal of Environmental Research - Year 2008, Vol 2, Issue 3
Abstract
Mercury is one of the most toxic heavy metals present in aquatic systems, exhibiting a complex behaviour in the environment, where it may persist for decades after the source of pollution is stopped. Hence, it is important develop new techniques for its removal from the aquatic systems. In this context, a particularly promising line of research is the use of new materials capable of up taking mercury from aqueous systems. A new sorbent system for removing mercury (II) in presence of oleic acid, from aqueous solutions has been investigated. This new sorbent is waste crushed brick, obtained from local industries .Variables of the system include solution pH, sorbent dose and contact time. The adsorption isotherm data follow the Langmuir equation in which characteristic parameters was calculated. Waste crushed brick has a maximum mercury (II) removal capacity (87mg/g).
