DOI: 10.1016/j.ijbiomac.2016.11.085

Abstract: Chitosan was prepared by alkaline N-deacetylation of β-chitin from squid pens. Thiosemicarbazide group was introduced to chitosan via formaldehyde-derived linkages, and thiosemicarbazide chitosan (TSFCS) with different degrees of substitution (DS) was synthesized. The DS values… read more here.

DOI: 10.1080/03067319.2019.1683552

Abstract: ABSTRACT A designed new adsorbent by coupling chitosan and 1-Amino-2-naphthol-4-sulphonic acid to get an excellent synergistic effect of 1-Amino-2-naphthol-4-sulphonic coupled chitosan (ANSC) which used for the removal of tetravalent thorium ions. The modified chitosan adsorbent… read more here.
