Removal of Hg(II) from aqueous solutions using cassava industrial waste was studied varying pH and metal initial concentration. The adsorbent material was pretreated and characterized. The adsorption kinetic was adjusted to a first order model and the equilibrium time was 2 hours. The maximum adsorption achieved was 0.03 mmol/g at pH 6 and 400 mg/L of mercury (II) initial concentration. Also, the results obtained at pH 4.75 and 6 had a good fitting to Langmuir adsorption isotherm model. [ABSTRACT FROM AUTHOR]
