Herein, we report for the first time a novel electrochemical sensor for the simultaneous detection of para‐aminophenol (p‐AP) and hydroquinone (HQ) in aqueous medium using Tricholoma mushroom polysaccharide based graft copolymer‐Au composite nanoparticles (TMPG−Au NPs). The graft copolymer is synthesised by radical polymerization technique in aqueous medium using a mixture of acrylamide (AM), acrylic acid (AA) and Tricholoma mushroom polysaccharide (TMP). Further, TMPG−Au NPs is prepared using the graft copolymer as a reducing as well as stabilizing agent by green technique. The graft copolymer and TMPG−Au NPs are properly characterised. The detection of p‐AP and HQ in aqueous medium is carried out by linear sweep voltammetry (LSV) and Chronoamperometry (CA) without interfering other common phenolic compounds and environmentally relevant metal ions. In LSV experiment the p‐AP and HQ show clear and distinct oxidation peaks at 0.0814 V and −0.077 V respectively. The proposed sensor successfully detects p‐AP and HQ with very low detection limit 0.41 μM and 0.32 μM respectively and effectively.

A new type of temperature‐responsive electrochemical sensor was constructed based on a glass carbon electrode modified by the composite containing temperature‐responsive polymer polystyrene‐poly N, N‐diethyl acrylamide‐polystyrene (PS‐PDEA‐PS) and fullerenes‐carboxylate multi‐walled carbon nanotubes (C60‐MWCNTs). The sensor was used for the electrochemical detection of catechol (CC). When the temperature is higher than the critical temperature (LCST) of PS‐PDEA‐PS, the electrochemical behavior of CC can be detected, which it is in the “on” state. When the temperature is lower than LCST, the composite modified film is in the “off” state and the electrochemical behavior of CC was not detected. Under the best experimental conditions, the sensor has a good detection range for catechol from 4.0 to 135.0 μM, with a LOD of 1.45 μM. In addition, the proposed sensor has good stability and reproducibility, and was successfully applied to the determination of catechol in real tap water.

“…Therefore, the monitoring of CT in environmental samples is quite necessary. A series of analytic techniques, including electrochemiluminescence, electrochemistry approaches, spectro‐photometry and high performance liquid chromatography (HPLC) have been adopted for the detection of CT. Unfortunately, it is inconvenient for these methods to determine CT because of the sophisticated operations and expensive instrumentation.…”

In this paper, a novel chemiluminescence (CL) system was introduced based on the use of CdTe quantum dots (QDs) with the mixture solutions of fluorescein and potassium periodate (KIO ) in alkaline medium. The CL signal of an ultra-weak system was strongly enhanced in the presence of QDs. The application of CdTe QDs-fluorescein-KIO system is reported for the first time. It was found that catechol had a diminishing effect on the CL reaction. Under optimal experimental conditions, CL intensity decreased linearly in a 1 to 100 μM catechol concentration range, with a 0.18 μM detection limit. A possible reaction mechanism was proposed according to the results of kinetic analyses, CL spectra, ultraviolet-visible and fluorescence spectra. The results pointed to an efficient energy transfer between the CL energy donor CdTe QDs and acceptor fluorescein. Finally, the CL method was successfully applied to the determination of catechol in environmental water samples.
