Legislation based on the <i>Codex Alimentarius</i> establishes quality control parameters essential for ensuring the safety and quality of honey. These parameters include the measurement of hydroxymethylfurfural (HMF), an indicator of honey quality. Currently, the primary methods for determining HMF concentration in honey are spectrophotometric and chromatographic tests. This study proposes a simpler alternative electroanalytical methodology that uses a screen-printed carbon electrode to monitor the HMF in honey. This portable technique offers advantages over commonly used methods, such as lower cost, similar efficacy, and requirement of only 70 µL of solution per analysis. Square-wave voltammetry was employed to determine HMF in Britton-Robinson buffer (pH 9.0), and the technique was optimized based on the experimental design, generating statistical chemical prediction results. The optimal values for modulation amplitude, step potential, and frequency were 81.5 mV, 22.5 mV, and 5 Hz, respectively. The recovery rate was within the limits established by AOAC International (80–110%), except for the concentration of 6.0 × 10⁻⁷ mol L⁻¹, which showed a 2.07% higher recovery, indicating a minor matrix effect. The calibration curve had an <i>R</i>² value of 99%, with a limit of detection of 6.76 × 10⁻⁸ mol L⁻¹ and a limit of quantification of 2.23 × 10⁻⁷ mol L⁻¹. Therefore, a rapid, cost-effective, and efficient methodology was established to quantify HMF in honey.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3><p>A simpler and portable electroanalytical methodology based on screen-printed carbon electrodes to determine the HMF in honey</p>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"60 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142247487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some widely employed industrial processes are major contributors to CO₂ emissions. A prime example is ammonia production, which represents a high energy consumption, utilizes natural gas, and generates hundreds of millions of tons of CO₂ annually. Proper waste treatment, alternatives to fossil fuels, and chemical compound production processes are crucial to address these issues. In this regard, (photo)electrochemical techniques such as electrocatalysis (EC) and photoelectrocatalysis (PEC) can aid in the clean and cost-effective treatment of wastewater while also generating new fuels and commercially valuable chemical compounds. Reduction reactions can be specifically applied to (i) CO₂ molecules, producing fuels; (ii) N₂ molecules, generating NH₃; and (iii) H + species, producing H₂. Oxidation reactions can be employed for organic and inorganic molecules present in real effluents, aiming to treat contaminated water. Electrocatalytic Brazilian research groups have been contributing not only to those redox reaction investigations but also to the synthesis of electrocatalysts for both reactions, making them more cost-effective, specific, and efficient, opening new perspectives in the generation of environmentally friendly chemical compounds with added value, clean energy conversion (non-petroleum energy), and minimizing the economic impact of environmental wastewater treatments.
