Methacrylic functionalized hybrid carbon nanomaterial for the selective adsorption and detection of progesterone in wastewater

Progesterone, an endocrine-disrupting chemical, has been frequently detected in wastewater for decades, posing a serious threat to ecological and human health. However, it is still challenge achieve the effective detection of progesterone complex matrices water samples. In this study, novel adsorbent CNT@CS/P(MAA) was prepared by grafting methacrylic polymers on surface modified carbon nanomaterials. Compared with other reported materials, hybrid nanomaterial could selectively identify industrial pharmaceutical wastewater, its adsorption performance almost independent pH environmental temperature. addition, be reused good recovery rate. The nanomaterials were characterized transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, nitrogen desorption experiments, thermogravimetric analysis. results confirmed that chitosan layer successfully grafted nanotubes. Adsorption isotherms, kinetics, selectivity tests showed had high capacity (44.45 mg·g?1), fast rate satisfied progesterone. Then, used as solid phase extraction sorbent combined HPLC enrich from Under optimum conditions, linearity obtained correlation coefficient 0.9998, limit 0.003 ng·mL?1. Therefore, method selective substrates provided new waters.
