Sensitive voltammetric determination of bromate by using ion-exchange property of a Sn(II)-clinoptilolite-modified carbon paste electrode

The effect of some strong oxidizing agents was studied, and the results showed that when such agents are present at levels of 2.5 to 5 times greater than the bromate in the solution, they can cause a maximum error of 3% in the determination of bromate in sulfuric acid electrolyte at pH 2.5

Scholarcy highlights

  • A modified carbon paste electrode with Sn(II)-exchanged clinoptilolite nanoparticles showed voltammetric current) for Sn(II)/Sn(IV) in sulfuric acid electrolyte
  • The peak current was decreased when bromate was added to the solution
  • This decrease was used for indirect voltammetric determination of bromate
  • The effect of some strong oxidizing agents was studied, and the results showed that when such agents are present at levels of 2.5 to 5 times greater than the bromate in the solution, they can cause a maximum error of 3% in the determination of bromate in sulfuric acid electrolyte at pH 2.5
