This study investigates the effect of deacetylation degree and molecular weight of chitosan on molybdate sorption on both raw and glutaraldehyde crosslinked samples. It appears that the physicochemical parameters affect the crystallinity of the samples: a high crystallinity reduces the accessibility of both water and metal ions to the amine binding sites. Both equilibrium and kinetic performances are thus influenced. The crosslinking by glutaraldehyde decreases sorption performances for large size particles while it does not influence sorption for the smallest.
Conventional and starch xanthide (SX) reinforced styrene‐butadiene (SBR) rubbers from several molding compounds and a tire tread compound were compared during 90 days' storage at various controlled humidities and during 1 year's outdoor weathering. For practical compounds, where SX served as a replacement for silica or as a partial replacement for carbon black, there was little difference between conventional and corresponding SX reinforced SBR rubbers. Properly formulated SX reinforced rubbers would prove satisfactory even in demanding applications.
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.
