| Abstract: | A method is reported for the determination of methyl violet in the range of 10–120 nmol L?1. The method is based on the catalytic effect of silver nanoparticles (AgNPs) on the oxidation reaction of methyl violet by potassium bromate in acid medium. The reaction is followed spectrophotometrically by measuring the change in absorbance ( | |
