Summary: The simultaneous determination of hydroquinone and catechol was achieved using a glassy carbon electrode modified with Gold Nanoparticles (AuNP) and functionalized multiwalled carbon nanotubes. Good response, sensitivity, and detection limits were observed in winery wastewater samples, with the developed method also showing reliability in spiked tap water and industrial wastewater. Additionally, chemometric tools were successfully used to quantify both isomers in real matrices with prediction errors of lower than 10% in fortified wastewater.

Summary: In this study, a leaf-shaped iron-doped metal-organic framework (MOF) was synthesized and carbonized to obtain iron and nitrogen doped carbon nanonets with a unique three-dimensional network structure (Fe,N-CNs). These Fe,N-CNs were used to construct a highly sensitive electrochemical sensor for simultaneous detection of catechol and hydroquinone. The proposed sensor exhibited a wider linear range, good stability, reproducibility, and selectivity, suggesting its potential applications.

Summary: Ce-MOF/CNTs nanocomposites were prepared by a simple method and post-treated with NaOH/H2O2 mixed solution. The morphology and structure of the treated samples were characterized by various techniques, and the results showed a morphological change in Ce-MOF and the presence of two valence states of Ce3+/Ce4+ in the composite. The nanocomposites were used to fabricate an electrochemical sensor for the simultaneous detection of hydroquinone (HQ) and catechol (CC) with improved performance compared to the untreated samples.

Summary: In this study, carbon sub-micro spheres (SMSC) were synthesized using Sargassum coriifolium seaweed, and a SMSC-modified glassy carbon electrode (SMSC/GCE) was fabricated for the simultaneous detection of hydroquinone (HQ) and catechol (CT). The morphology, structure, and electrochemical properties of SMSC were characterized using various analytical techniques. The SMSC/GCE exhibited a linear concentration range of 10-200 μM and low detection limits for HQ and CT. The kinetic parameters and interfacial interactions were investigated, and the proposed electrochemical sensor showed high sensitivity, anti-interference capability, stability, reproducibility, and satisfactory recovery for determining isomers in tap water.

Summary: A novel porphyrin-metal organic frameworks (MOFs) based hybrid composite was created by combining conductive carbon black (CB) and PCN-222(Fe) via a one-pot strategy. The proposed material takes advantage of the high specific area from MOFs and the strong conductivity of CB, contributing to contact with analytes and detection sensitivity. It has been demonstrated that the modified electrode can be an alternative candidate for electrochemical detection of dihydroxybenzene isomers.
