dc.description.abstractIn this study, novel blend hydrogel beads were prepared for the use in removal of anionic textile dyes due to their hazardous impact to nature. Sodium alginate and sodium alginate/poly(N-vinyl-2-pyrrolidone) beads were prepared by gelation method into calcium chloride solution. Prepared blend beads were characterized by TGA and FTIR analysis, and they were successfully used in adsorption of the reactive red-120 (RR), cibacron brilliant red 3B-A (CBR) and remazol brilliant blue R (RBB) in batch system. The effects of various parameters such as pH, initial dye concentration, contact time and temperature onto adsorption were investigated. The maximum adsorption capacities were found 116.8, 73.3 and 55.3 mg g(-1) for RR, CBR and RBB, respectively. The adsorption of dyes was well described by pseudo-second-order kinetics and Langmuir isotherm. Thermodynamic parameters indicated that the adsorption is spontaneous and exothermic. These results have shown that blend hydrogel beads can be effectively used as adsorbent in the removal of dyes from harmful wastewaters.en_US
