Introduction: The water pollution remediation is a challenging topic in environmental science. The purpose of this study was to achieve the practical methods for evaluation of the efficiency of latest modern technologies in order to remove dyes from the aqueous solution.
Methods: In this experimental study, we used nanotechnology technique for production of the Sodium alginate magnetic beads by the chemical precipitation method. The adsorption experiments data was compilanced by the Langmuir and Frenundich isotherm models. We examined the removal of the acid cyanine 5R dye from synthetic wastewater samples by using the synthesized beads in batch reactor.The effect of environmental factor (such as pH, contact time, adsorbate and adsorbent concentration) on the efficiency of removal of acid cyanine 5R has been studied. Composition of Alginate magnetic beeds (calcium, soudium and ferrous) determined by atomic adsorbtion instrument. The dye concentration in the samples was measured by spectrometry method using a UV-1700 Pharmaspec Shimadzo spectrophotometer at 574 nm wavelengh.
Results: The efficiency of sodium alginate magnetic beads to remove the Acid Cyanine 5R had a direct relationship with contact time and inverse relationship with dye concentration. Relationship between contact time and efficiency of dye removal showed the equilibrium acquire after 210 minute. The maximum efficiency of dye removal was in initial concentration of 50 ppm. The results also showed the adsorption of Acid Cyanine 5R complies with Freundlich isotherm model.
Conclusion: Generally from environmental view this process is safer and it can compet with other common methods. So, we recommended this method for removal of pollution from aqueous solution.
