Preparation of versatile polymer particles and their application for elimination of bromophenol blue and phenol from aqueous environment

Abstract

Cellulose, activated carbon, zeolite, and similar materials have a weak effect against anionic pollutants. Therefore, further modifications are needed for the use of such substances. In this study, polymer particles (GD) that were economical and directly effective against anionic pollutants were synthesized as an alternative. GD particles were synthesized with glutaraldehyde and diethylenetriamine as monomers for the first time. The polymer particles were characterized in detail. Then, GD particles were used in the adsorption of anionic Bromophenol blue (BPB) and phenol (PH). As a result, it was determined that i) the adsorption process between GD particles, Bromophenol blue and phenol was chemisorption, ii) the adsorption of BPB and PH on to GD particles obeyed the Langmuir isotherm and pseudo second order kinetic model. pH, temperature, initial dye concentration, adsorbent dosage, and contact time were determined orderly 4, 50 °C, 300 mg L−1, 10 mg, and 180 mins for BPB and 5, 50 °C, 10 mg L−1, 15 mg, and 30 mins for PH. The maximum adsorption capacities of GD polymer particles for BPB and PH were ascertained as 136.40 mg g−1 and 98.26 mg g−1, respectively. As a result, it was produced economical, simple, feasible, and functional adsorbents against anionic pollutants.
