Abstract:The chemical modification on chitosan (CTS) was carried out by cross-linking it with precursor compound 3,3 0 -dimethoxy-4,4 0 -dihydroxy-5,5 0 -bis(N,N 0 -piperazine-1-yl methyl benzaldehyde), (PC) in order to improve the metal ion adsorption capacities and selectivity of the product. The resulting crosslinked chitosan derivative (CCTSL) was characterized by elemental analysis, Fourier transform infrared spectrum (FTIR), Differential Scanning calorimetry (DSC), Scanning Electron Microscopy (SEM) and powder X-… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
