Abstract

SANCHEZ, Julio; BUTTER, Bryan  and  RIVAS, Bernabé L.. BIOPOLYMERS APPLIED TO REMOVE METAL IONS THROUGH ULTRAFILTRATION. A REVIEW. J. Chil. Chem. Soc. [online]. 2020, vol.65, n.4, pp.5004-5010. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072020000405004.

This manuscript is an overview of the versatile biopolymer materials alginic acid, carboxymethyl cellulose, and quaternized chitosan which contain different functional groups to remove hazardous inorganic species. These bioadsorbents are completely water-soluble and have a high versatility to achieve a higher sorption capacity and efficiency under different experimental conditions in combination with ultrafiltration membranes through the liquid-phase polymer-based retention (LPR) technique. In general, thesebioadsorbents are friendly with the environment and have a higher biodegradability compared with those more employed synthetic polymers.

Keywords : Biopolymers; Ultrafiltration membranes; Metal ions; Removal.
