Preparation and Adsorption Properties of Gelatin Microspheres for Cationic Dye

Abstract:

Gelatin microspheres (GMSs) were prepared by the inverse suspension cross-linking reaction, using glutaraldehyde as the cross-linking reagent. The GMSs was characterised by scanning electron microscopy and laser particle size analyzer. The effects of various experimental parameters, such as pH, temperature, adsorbent dosage and contact time were investigated in a batch-adsorption technique. The optimum conditions for removal of the cationic red X-GRL (CRX) dye were found to be pH 9, temperature 40 °C, 0.9 g/L of adsorbent dosage and adsorption time of 120 min, respectively. The adsorption capacity increased from 402.16 to 510.82 mg/g with the increase of stirring rate from10 to 300 rpm and decreased from 479.35 to 412.54 mg/g with the increase of sodium sulphate concentration from 0 to 8 g/L. The biomass GMSs had a substantial potential for removing cationic dye from wastewater owing to great adsorption capacity and adsorption rate to dye.
