General description

Used to neutralize acids, hydrolyze fats, and precipitate alkaloids and metals from aqueous solutions.

Application


  • Protein N-linked Homocysteine Determination: Employing sodium hydroxide pellets in a one-pot sample preparation procedure for the analysis of protein N-linked homocysteine using HPLC-FLD, demonstrating its critical role in chemical synthesis and laboratory applications (Piechocka and Głowacki, 2023).

  • Algae Pyrolysis for Hydrogen Production: The use of sodium hydroxide pellets in a molten state combined with Na2CO3 for efficient hydrogen production from algae pyrolysis. This application underscores its potential in renewable energy sectors and environmental sustainability efforts (Li et al., 2023).

  • Hydrothermal Synthesis of ZnO Superstructures: Research into the temperature and pH optimization using sodium hydroxide pellets for the hydrothermal synthesis of ZnO superstructures. This application is crucial for material science, particularly in developing nanomaterials with specific morphological properties (Ejsmont and Goscianska, 2023).
