Chitin is a structural polysaccharide that is found in crustaceans, insects, fungi and some yeasts. Chitin deacetylation produces chitosan, a well-studied biopolymer with reported chemical and biological properties for diverse potential applications for drug delivery, metal ion absorption, scaffolds and tissue engineering. Most known properties of chitosan have been determined from samples obtained from a variety of sources and in different conditions, this is, from chitosans with a wide range of degrees of N-acetylation (DA) and molecular weight (MW). However, as for any copolymer, the physicochemical and mechanical characteristics of chitosan highly depend on their monomer composition (DA) and chain size (MW). This work presents a simple methodology to produce chitosans with specific and predictive DA and MW. Reaction with acetic anhydride proved to be an efficient method to control the acetylation of chitosan, DAs between 10.6% and 50.6% were reproducibly obtained. In addition to this, MWs of chitosan chains were reduced in a controlled manner in two ways, by ultrasound and by acidic hydrolysis at different temperatures, samples with MWs between 130 kDa and 1300 kDa were obtained. DAs were determined by 1H-NMR and MWs by gel permeation chromatography.

ABSTRACTResearch utilization of mangrove snail chitosan conech shell (Telescopium sp) as a binding metal ions of lead (Pb) in solution. This study aims to determine the best time of the metal ion absorption of lead (Pb) by a conch shell chitosan mangrove (Telescopium sp) with the remains of 150 rpm shaking method. This research was conducted by completely randomized design (CRD) and 4 variations of shaking time is 50, 55, 60 and 65 minutes. Each treatment was repeated three times. The results obtained are binding Pb (II) by the highest chitosan during 65 minutes agitation is 98.27%. Key words: Chitosan, absorption, lead
