Abstract

The powder of fruit waste Chiku was used as adsorbent for removal of heavy metals like Fe (III), Cu (II) and Cr (II) from aqueous solution. Batch experiments were carried out as a function of varying adsorbent dose, temperature and time. The adsorption equilibrium data matches well with Freundlich and Langmuir adsorption models. The thermodynamic study reveals that the Fe (III), Cu (II), Cr (II) ions adsorption was spontaneous physical adsorption.
