Ionic gelation synthesis, characterization and adsorption studies of cross-linked chitosan-tripolyphosphate (CS-TPP) nanoparticles for removal of As (V) ions from aqueous solution: kinetic and isotherm studies
نویسندگان
چکیده
The CS-TPP nanoparticles were synthesized and their efficiency for removal of arsenic (V) ions at the optimum conditions was investigated. obtained with mass ratio tripolyphosphate to chitosan 1: 2 pH = 5.0. experimental data adsorption As followed Freundlich isotherm maximum capacity 77 mg/g 6.0. All experiments performed room temperature (25 °C). crosslinking sodium led a decrease in crystallinity formed particles which then resulted an improvement metal ion sorption properties.
