Abstract
The aim of this work is
the use of Amberlite IRN 150 resin in the removal of Cr (III) and
Cr (VI) from tanning and chrom e plating waste water s respectively Removal experiments
were carried out in ba tch Kenitics and equilibrium studies were undertaken using various
models The obtained results show that the increase in pH implies an increase of Cr (III)
removal in tanning water and a decrease of Cr (VI) removal in chrome plating water. In the
two cases , t he exchange kinetics is well described by the second order model . The removal of
the two ions by IRN150 is not limited by intraparticular diffusion. The Freundlich isotherm is
more suitable for describing Cr(III) removal in tanning water . H owever, in ch rom e plating
water , Cr (VI) removal is better described by the Langmuir isotherm.
