Breakthrough and thermodynamic adsorption of Cr (VI) y Ni (II) bioadsorption in continuous system

The removal of heavy metals present in water is an issue environmental interest, due to bioaccumulation,
 biomagnification and the carcinogenic mutagenic effects on living beings. objective study was use plantain peel residues Chromium (VI) Nickel (II) continuous system, evaluating effect bedheight, temperature adsorbent particle size process; obtaining a 98.7% 99.71% yield for Cr Ni(II), respectively. FTIR showed that bioadsorbent has
 heterogeneous structure with presence hydroxyl groups, saturated unsaturated hydrocarbons, carbonyls, carboxyl, among others, it established process controlled by electrostatic reactions between active centers metal. breaka ge curve carried out under optimal conditions Response Surface Methodology (RSM) the
 has extensive useful life, as not throughout process. hermodynamic parameters exothermic irreversible, being favored at room temperature. Taking into account behavior peels during breakage curve, recommended filler packed bed remove Ni (II).
