应用


  • Adsorption Studies: Sodium hydroxide solution is used in treating polymer adsorbents to enhance their adsorption properties. A recent study investigated the effect of treating a PVC/Aliquat-336 polymer adsorbent with sodium hydroxide on chromium (VI) adsorption. The treatment improved the adsorption capacity of the polymer, making it more effective in removing heavy metals from aqueous solutions (Ouazine et al., International Journal of Environmental Analytical Chemistry, 2022).

  • Synthesis of Sodium Ethoxide: Sodium hydroxide solution is employed in the synthesis of sodium ethoxide, an important reagent in organic synthesis. Research has demonstrated that sodium ethoxide can be synthesized efficiently at ambient temperature using sodium hydroxide and ethanol-90. This method offers a straightforward and cost-effective approach for preparing this key chemical intermediate (Randriana et al., World Journal of Applied Chemistry, 2021).

  • Corrosion Inhibition: Sodium hydroxide solution is used in corrosion inhibition studies. Research has shown that an aqueous extract of Thespesia populnea plant leaves can effectively inhibit the corrosion of aluminum steel in sodium hydroxide solution. The study utilized electrochemical techniques to demonstrate the formation of a protective film on the steel surface, highlighting the potential of natural inhibitors in industrial applications (Brindha and Venkatraman, Research Journal of Chemistry and Environment, 2023).
