摘要

Magnetic chitosan biopolymer, successfully grafted over graphene oxide (MCGO), employed for the efficient extraction of endocrine disrupting phenolic compounds (bisphenol A, 4-tertiary butylphenol and 4-tertiary octylphenol) in single analysis with high performance liquid chromatography. At optimum conditions the adsorption ability calculated for bisphenol A (BPA), 4-tertiary butylphenol (4-tertBP) and 4-tertiary octylphenol (4-tertOP) was 28.98 mgg(-1), 33.22 mgg(-1) and 24.31 mgg(-1), respectively. The results found in the current study showed pseudo second order kinetic and Langmuir adsorption isotherm followed. Suitable extraction solvent was methanol and water in 1:1 ratio and the extraction recoveries calculated for BPA, 4-tertOP and 4-tertBP with relative standard deviations were 92.56% +/- 3.10, 95.23% +/- 4.02 and 95.81% +/- 3.65, respectively. The method was also checked for green chemistry to calculate the eco scale environmental score. The promising adsorbent was also applied effectively to spiked wastewater samples including river water and industrial wastewater.
