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.

磁性壳聚糖生物聚合物成功接枝在氧化石墨烯（MCGO）上，用于高效液相色谱的单次分析中，有效提取内分泌干扰性酚类化合物（双酚A，4-叔丁基苯酚和4-叔辛基苯酚）。在最佳条件下为双酚A（BPA）中计算出的吸附能力强，4-叔丁基苯酚（4-tertBP）和4-叔辛基苯酚（4- tertOP）为28.98 MGG ^-1，33.22 MGG ^-1和24.31 MGG ^-1， 分别。在当前研究中发现的结果显示出伪二级动力学和随后的Langmuir吸附等温线。合适的萃取溶剂为甲醇和水，比例为1：1，对BPA，4-tertOP和4-tertBP的萃取回收率的相对标准偏差分别为92.56％±3.10、95.23％±4.02和95.81％±3.65。还对该方法进行了绿色化学检查，以计算生态规模环境得分。前景光明的吸附剂还有效地应用于加标废水样品，包括河水和工业废水。
