Abstract
Para-aminophenol (4-AP) is the toxic hydrolysate of the pharmaceutical molecule p-acetaminophen (ACOP) and their overexposure is harmful to ecological environment and physical health, So, designing a reasonable and efficient sensing platform for simultaneous detection of the trace targets is urgent. In this study, a novel electrochemical sensing interface was constructed for simultaneous detection of ACOP and 4-AP by in-situ growth of a flat rod-like lanthanide metal-organic framework Ce-MOF on MXene materials. 2D MXene nanosheets improved the conductivity and dispersion of the composites while Ce-MOF provided abundant adsorption sites and big specific surface area, thus significantly amplifying the electrochemical response signal. Post-oxidation of Ce-MOF induced electrocatalytic active Ce3 + /Ce4+ centers. As a result, the electrochemical sensor exhibited a wide linear range of 0.6 ∼ 360 μM and low detection limits (0.023 and 0.031 μM) for 4-AP and ACOP determination as well as satisfactory repeatability, stability and selectivity, and achieved accurate and synchronous detection of ACOP and 4-AP in actual tablets and environmental water samples.
期刊介绍:
The Journal of Environmental Chemical Engineering (JECE) serves as a platform for the dissemination of original and innovative research focusing on the advancement of environmentally-friendly, sustainable technologies. JECE emphasizes the transition towards a carbon-neutral circular economy and a self-sufficient bio-based economy. Topics covered include soil, water, wastewater, and air decontamination; pollution monitoring, prevention, and control; advanced analytics, sensors, impact and risk assessment methodologies in environmental chemical engineering; resource recovery (water, nutrients, materials, energy); industrial ecology; valorization of waste streams; waste management (including e-waste); climate-water-energy-food nexus; novel materials for environmental, chemical, and energy applications; sustainability and environmental safety; water digitalization, water data science, and machine learning; process integration and intensification; recent developments in green chemistry for synthesis, catalysis, and energy; and original research on contaminants of emerging concern, persistent chemicals, and priority substances, including microplastics, nanoplastics, nanomaterials, micropollutants, antimicrobial resistance genes, and emerging pathogens (viruses, bacteria, parasites) of environmental significance.
