Mercury is one ofthe most toxic heavy metals present in aquatic systems, exhibiting a compl ex behaviour in the environment, where it may persist for decades after the source ofpollution is stopped. Hence, it is important develop new techniques for its removal from the aquatic systems. In this context, a particularly promising line ofresearch is the use ofnew materials capable ofup taking mercury from aqueous systems. A new sorbent system for removing mercury (II) in presence ofoleic acid, from aqueous solutions has been investigated. This new sorbent is waste crushed brick, obtained from local industries .Variables ofthe system include solution pH, sorbent dose and contact time. The adsorption isotherm data followthe Langmuir equation in whichcharacteristic parameters was calculated. Waste crushed brick has a maximum mercury (II) removal capacity (87mg/g).
