Efficient removal of Cr(VI) by triethylenetetramine modified sodium alginate/carbonized chitosan composite via adsorption and photocatalytic reduction
TL;DR: In this article , a polysaccharide-derived composite was prepared by embedding carbonized chitosan into triethylenetetramine modified sodium alginate (CTS/CS-50).
Journal ArticleDOI
Enhanced Cr(VI) stabilization in soil by chitosan/bentonite composites.
TL;DR: In this article , chitosan/bentonite composites (CSBT) was synthesized and applied to the immobilization of chromium in the soil, and the results showed that CSBT could reduce the content of exchangeable form and oxidizable form, while increase the contents of residual form.
