General description

Sodium hydroxide solution is a strong alkali. It is utilized in making cellophane, rayon, bleaches, dyes and drugs. It is also employed to abstract hydrogen sulfide from petroleum and to degrade lignin in wood in the paper industry.

Application

Sodium hydroxide solution may be used in the following processes:
  • As a dedoping reagent in the synthesis of graphene/polyaniline hybrid material.
  • As a solvent in the weight loss study of aluminum by corrosion.4
  • Alkaline reagent test for tannins & phenolic compounds.
  • Synthesis of single crystalline zinc stannate (Zn2SnO4 and ZnSnO3) nanoparticles.
  • Estimation of protein content and α-cellulose content in grain by-products.
