Description

Application

• Voltammetric Determination: Potassium hydroxide solution in ethanol is used in voltammetric determination of antioxidants in various matrices. A recent study demonstrated its application in the voltammetric determination of the antioxidant 2,6-di-tert-butyl-p-cresol (T501) in transformer oil using a graphite electrode. This method enhances the sensitivity and accuracy of antioxidant detection, crucial for ensuring the stability and performance of oils and other industrial fluids (Zhou et al., Analytical Letters, 2021).


• Oxidative Degradation Studies: The reagent is employed in oxidative degradation studies of organic compounds. For instance, it has been used in the oxidative degradation of piperazine in potassium hydroxide solution for CO2 absorption processes. This application is essential for developing efficient CO2 capture and storage technologies, contributing to environmental sustainability and climate change mitigation (Ochedi et al., SSRN Electronic Journal, 2022).


• CO₂ Absorption and Modeling: Potassium hydroxide solution in ethanol is used in experimental and modeling studies of CO₂ absorption processes. Recent research has focused on the absorption of CO₂ into potassium hydroxide aqueous solution, providing valuable data for optimizing industrial CO₂ capture methods. This application is crucial for enhancing the efficiency and effectiveness of carbon capture technologies (Rastegar and Ghaemi, Heat and Mass Transfer, 2022).
