Abstract

The detection of hydrogen peroxide (H₂O₂) at elevated concentrations while eliminating oxygen interference presents a significant challenge. Nickel-based stainless steel, such as Hastelloy G35, has shown excellent corrosion resistance. However, it has never been used in electroanalysis. In this study, the electrochemical analysis of H₂O₂ was conducted for the first time using nickel-based stainless steel electrode. The Hastelloy G35 electrode exhibited a very wide linear range from 1 up to 1000 mM and a detection limit of 0.0135 mM. The method is free from interference by oxygen. This method effectively detected H₂O₂ in skin wound wash solutions with excellent recoveries. The excellent performance of this method enhances its applicability in various fields, including industrial processes, environmental monitoring, and analytical chemistry, where quantifying concentrated H₂O₂ is of utmost importance. It shows that nickel-based stainless steel is promising for electroanalysis.

哈氏G35电极对高浓度过氧化氢的电化学检测

检测高浓度过氧化氢（H2O2）同时消除氧干扰是一个重大挑战。镍基不锈钢，如哈氏合金G35，显示出优异的耐腐蚀性。然而，它从未在电分析中使用过。本研究首次采用镍基不锈钢电极对H2O2进行了电化学分析。哈氏合金G35电极的线性范围为1 ~ 1000 mM，检测限为0.0135 mM，该方法不受氧气干扰。该方法能有效检测皮肤创面洗液中的H2O2，回收率高。该方法的优异性能增强了其在工业过程、环境监测和分析化学等领域的适用性，在这些领域中，浓度H2O2的定量是至关重要的。这表明镍基不锈钢在电化学分析中具有广阔的应用前景。
