Optimization of batch and packed-bed column Cr(vi) adsorption of an amine-rich chitosan/polyethyleneimine composite: application in electroplating wastewater treatment

Abstract

Toxic oxyanions of Cr (VI) can be potentially removed by adsorbents with positively charged surfaces. In this study, we synthesized a stable and insoluble amine-rich polymer composite (CS-PEI-GLA) by crosslinking...
