The gelatin- montmorillonite intercalation composite was made by the intercalation between collagen and montmorillonite. The XRD and FTIR were used to characterize the composite. Results indicate that gelatin has intercalated into the interlayer of montmorillonite sucessfully. This composite was used as adsorbent for the discoloring of simulated reactive turquoise blue K-GL dyeing wastewater. Effects of time and p H on adsorption were explored. Results indicate that this adsorbent could adsorb reactive turq...
