Herein, a facile and enzyme-free CP sensor was fabricated by in situ electrochemical reduction strategy on the surface of glassy carbon electrode (GCE). Reduced graphene oxide (RGO) was chose as supporting materials for the distribution of platinum nanoparticles (Pt NPs) to obtain improved catalytic properties. The applicability and suitability of the obtained RGO-Pt/GCE for 4-CP detection were also evaluated. The results indicated that the RGO-Pt NPs modified electrode displayed much better catalysis and higher sensitivity for 4-CP oxidation. Under optimum conditions, the oxidation peak current was proportional to 4-CP concentration in the range from 0.1 to 500 μM with a detection limit of 51 nM. Meanwhile, it is demonstrated that the prepared sensor is also characterized by excellent feasibility, satisfactory reproducibility, good stability and high specificity. The results suggested that RGO-Pt/GCE could be a facile, costeffective, and rapid tool for the prospect on-line evaluation of 4-CP in drinking water samples.

The residue dynamics and risk assessment of prochloraz and its metabolite 2,4,6-trichlorophenol (2,4,6-TCP) in apple under different treatment concentrations were investigated using a GC-ECD method. The derivatization percent of prochloraz to 2,4,6-TCP was stable and complete. The recoveries of prochloraz and 2,4,6-TCP were 82.9–114.4%, and the coefficients of variation (CV) were 0.7–8.6% for the whole fruit, apple pulp, and apple peel samples. Under the application of 2 °C 2.0 g/L, 2 °C 1.0 g/L, 20 °C 2.0 g/L, and 20 °C 1.0 g/L treatment, the half-life for the degradation of prochloraz was 57.8–86.6 d in the whole fruit and apple peel, and the prochloraz concentration in the apple pulp increased gradually until a peak (0.72 mg·kg−1) was reached. The concentration of 2,4,6-TCP was below 0.1 mg·kg−1 in four treatment conditions and not detected (

Abstract2,4,6‐trichlorophenol (TCP) is regarded as a very harmful persistent organic pollutant. It is prohibited by the US EPA due to its stability, possible toxicity, and substantial carcinogenicity, which could result in long‐term harm to both the environment and living things. A novel solid‐contact electrode (SCE) is fabricated and characterized for potentiometric determination of 2,4,6‐trichlorophenol (2,4,6‐TCP). Molecularly imprinted trichlorophenol polymer (MIP) beads are used as a recognition receptor for potentiometric determination of this persistent organic pollutant. The MIPs are synthesized using 4‐vinyl pyridine (4‐VP) and N,N′‐Methylene bis(acrylamide) (N,N‐MBAA) as functional monomer and cross‐linking agent, respectively. They are embedded in a selective polyvinyl chloride (PVC) membrane on the top of multi‐walled carbon nanotubes (MWCNTs), which is used as an ion to electron transducer. The SCE exhibits a Nernstian response with a slope of −55.4±2.1 mV/decade (R2=0.999) over the concentration range of 8.0×10−6 to 1.0×10−4 M, a detection limit of 5.0×10−7 M (0.98 μg/mL), and a response time of <10 s. Using electrochemical impedance spectroscopy (EIS) and chronopotentiometry (CP), the suggested SCE′s interfacial capacitance is measured. The interfacial capacitance was increased using MWCNTs and reached 39.7 μF. Also, it prevented the undesirable thin water layer from forming between the conducting glassy carbon (GC) substrate and the sensing membrane. As a result, potential stability is improved, and membrane delamination is avoided. The suggested SCE had a wide range of applications for monitoring TCP in various environmental samples because of the high selectivity, sensitivity, and possible stability that were attained.
