Removal of basic fuchsin dye from aqueous solutions using graphite oxide modified aromatic polyurethane foam material

Abstract

AbstractGraphite oxide modified polyurethane foam (GO/PUF) was used for adsorption of basic fuchsin from aqueous solution and adsorption conditions were optimized to attain an efficiency of 99.5%. The adsorption isotherm was in agreement with the Langmuir model. Kinetic study followed pseudo-second order. Determination of Gibbs free energy and enthalpy change of adsorption indicated spontaneous and endothermic adsorption behavior, suggesting that the adsorbent had a potential for the removal of dyes from industrial wastewater.Keywords: foam materialadsorptiongraphite oxidebasic fuchsin dye Additional informationFundingThis project was supported by the Natural Science of Jiangsu Province [grant number BK20141298]; Society Development Fund of Zhenjiang [grant number SH2013020]; Project of Science and Technology of Suzhou [grant number SG201338].
