Use of activated clays in the removal of dyes and surfactants from tannery waste waters
Source abstract
Abstract
The capacity of sepiolite and acid-activated bentonite to adsorb anionic dyes normally used in the tannery was much greater than that of conventional adsorbents. A surfactant removal of 90% was achieved in approximately 10 min because of the high affinity between surfactant and adsorbent. Natural bentonite activated with 0.5 M H2SO4 was the most effective adsorbent for ethoxylated nonylphenol.
