The nano-magnetite-loaded 2-mercaptobenzoxazole as an adsorbent for the selective removal of the Pb2+, Ni2+ and Cd2+ ions from aqueous solutions
Ariannezhad M, Habibi D, Heydari S, Khorramabadi V
The present research focuses on the adsorption efficiency of nano-magnetite loaded 2-mercapto- benzoxazole as an adsorbent (Fe3O4@SiO2@CPTMS@MBOL) for Pb+2, Ni+2 and Cd+2 removal from the contaminated water by the technique of adsorption. The influence of pH, contact time, adsorbent dosage and temperature in 50 ppm concentration of each ion solutions on the sensitivity of the removal procedure was examined. By ICP test the adsorption data were fixed to linearize the adsorption isotherms of the Langmuir and Freundlich equations. This efficient adsorbent showed significant results for metal ion removal from water by formation of complex with adsorbent. From the Langmuir isotherm, the maximum adsorption capacities of nano magnetic adsorbent towards Pb2+, Ni2+ and Cd2+ ions were 238.4, 203.2 and 22.37mgg-1.
