Application
- Biosorbent derived from coffee husk for efficient removal of toxic heavy metals from wastewater.: Researchers developed a biosorbent from coffee husk to remove heavy metals from wastewater. Sodium hydroxide plays a critical role in the chemical activation of the coffee husk, enhancing its adsorption capacity (Quyen et al., 2021).
- Development of Advanced Chemometric-Assisted Spectrophotometric Methods for the Determination of Cromolyn Sodium and Its Alkaline Degradation Products.: This paper presents advanced spectrophotometric methods for analyzing cromolyn sodium and its degradation products. Sodium hydroxide is used to induce the degradation of cromolyn sodium, allowing for the study of its breakdown products (El Zahar et al., 2020).
- High resolution and high throughput analytical methods for d-tagatose and process related impurities using capillary electrophoresis.: The study develops capillary electrophoresis methods for analyzing d-tagatose and its impurities. Sodium hydroxide is employed as an electrolyte to enhance the separation and resolution in the electrophoresis process (Surapureddi et al., 2020).
- Phosphorus in recycling fertilizers - analytical challenges.: This research addresses the analytical challenges in determining phosphorus in recycling fertilizers. Sodium hydroxide is used to adjust the pH of samples, which is crucial for accurate phosphorus quantification (Krüger and Adam, 2017).
