Resumen:
Based on its cation exchanger capacity, carboxymethylcellulose (CMC) has been reported to be useful for the adsorption of heavy metals from water1,2. Commercial CMC is generally produced from cellulose feedstocks obtained from kraft and acid sulphite pulps derived from wood, or directly from cotton linters. In the current contribution carboxymethylation of cellulose from bacterial origin (BC) is proposed. Reaction conditions were manipulated aiming to tailor the carboxymethylation extent conferred to BC (i.e. degree of substitution, DS) in order to obtain insoluble products with high lead uptake capacity.
