“…The adsorption of As 3þ and As 5þ metal ions were conducted at 25 C in aqueous medium. The sorption capacity of the composite was found to be 79.4 and 74.6 mg/g of chitosan, respectively for As 5þ and As 3þ (Boddu, Smith, & Nano, 2001). Veera et al (2008) studied the effect of pH on the sorption of As 5þ and As 3þ using the above chitosan/a-alumina biocomposite.…”

Polymeric sorbents and biocomposites a b s t r a c t Various sorbents have been used to remove arsenic from contaminated water which is one of the most toxic elements for mankind. In this review, concentration has been focused on the removal of arsenic from aqueous medium using natural, non-toxic, biodegradable and eco-friendly polymeric materials. Therefore, chitosan has been selected one of the most appropriate biopolymer to remove heavy metals form contaminated water particularly arsenic. Therefore, chitosan grafting, blending, doping and biocomposite formulations with polymeric and/or activated inorganic materials have gained much attention. This review provides the relevant literature on the applications of polymeric biocomposites for removal of arsenic from aqueous medium. However, the literature survey reveals that very limited attention has been focused on the applications of biocomposites for the removal of arsenic in the past. The sorption capacities of sorbents and LD 50 of the arsenic compounds have been compiled.

“…Because to infer its porous structure should have a higher adsorption capability and further applications such as drug delivery and anti-cancer. Studies on chemical modification of chitosan have been extensively performed to introduce novel functions (4). Recently, we have succeeded in the synthesis of chitosan containing chalcone moiety.…”

Versatile hybrid organic polymers are prepared using two active intermediates such as cynuric chloride and chitosan derivatives. The prepared chalcones are characterized by using FT-IR, UV, and proton NMR, thermal analysis and Minimum inhibitory Concentration. Thermal stability of the synthesized hybrid polymer is found using TGA and the hybrid chitosan derivative chalcone is thermally stable up to 270 °C. The antimicrobial activity of the prepared chitosan containing chalcone moiety are find out using Minimum Inhibitory Concentration (MIC) method. The synthesized versatile chalcone shows excellent antimicrobial activity against gram-negative bacteria such as Pseudomonas aeruginosa; and Gram-positive bacteria Chalcone containing halogen moiety shows high activity (MIC 7.8 µg/mL) than the hydroxyl containing chalcone. Cytotoxicity activity of the synthesized composites shows high activity.
