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

Abstract

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

Benzoyl isothiocyanate modified surface of silica gel as the extraction material for adsorbing steroid hormones in water

“…The coexistence of impurities in wastewater and surface water interfered with the enrichment and detection of steroid hormones and affected the extraction efficiency. 40 As shown in Fig. 8(b), the modified silica gel had higher recovery rate than that of unmodified silica gel and commercial C18 silica gel for the extraction of 3 steroid hormones (100 μg L −1 ).…”

Functional nanostructures in analytical chemistry: new insights into the optical and electrochemical sensing of animal hormones in food, environmental and biological samples

“…Another fluorescence-based strategy employed for the analysis of progesterone used a carbon nanomaterial conjugated with methacrylic. 91 A good linearity was observed under ideal conditions, with a correlation coefficient of 0.9998 and LOD of 0.00953 nM. Consequently, this method could be utilised to identify progesterone in industrial effluent, as well as providing a new way for detecting progesterone in other environmental fluids.…”

Advances in electrochemical sensors based on nanomaterials for the detection of lipid hormone

“…Progesterone is most commonly used as a pregnancy biomarker (Goh et al, 2016), which also has a central role in biology and medicine (Kanninen et al, 2019;Polat et al, 2020). Monitoring progesterone concentrations has been reported to be important in the autoimmune disease in women during menstruation (Chang and Wang, 2020), the dairy industry that can supply trustworthy data on mammalian reproduction by keeping track of progesterone levels (Yu and Maeda, 2017) and the environmental health protection by monitoring the progesterone in the wastewater (Cui et al, 2021).…”
