The endocrine disruptor compounds (EDC) are inevitable hazardous pollutants usually found in the discharged wastewater effluents, polluting the natural water bodies. This can be rationalised by the ineffective anal. methods that fail to quantify EDC in the treated wastewaters, forestalling the advancement of wastewater treatment processes that could completely mineralize the EDC. Therefore, a novel polypropylene membrane protected micro-solid-phase extraction (μ-SPE) device was developed using MXene encapsulated sorbent in enhancing the anal. of mixed EDC, namely, triclosan, triclocarban, 2-phenylphenol, bisphenol A and 4-tert-octylphenol, via a high-performance liquid chromatog.-diode array detector approach. The green adsorption-desorption of EDC from polypropylene membrane protected μ-SPE device was optimized at sorbent loading of 2 mg, extraction time of 30 min, sodium chloride of 15% (w/v), medium pH of 8, a sample volume of 10 mL, desorption solvent of isopropanol, desorption time of 3 min and desorption solvent volume of merely 150μL. Under the optimum condition, the proposed method showed a good EDC detection limit ranging from 0.37 to 0.58μg L-1 with acceptable relative recoveries between 81.0% and 105.5%. Moreover, the calculated enrichment factors also confirmed the EDC selectivity by polypropylene membrane protected μ-SPE device followed triclosan > 4-tert-octylphenol > bisphenol A > triclocarban > 2-phenylphenol. Finally, the polypropylene membrane protected μ-SPE device was assessed using real water, and wastewater samples and the EDC of triclosan and 4-tert-octylphenol were detected in the municipal wastewater and lake water, resp. In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Formula: C13H9Cl3N2O).
1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Formula: C13H9Cl3N2O
