Sensitive nanosilver-based spectrophotometric determination of Brilliant Blue FCF in surface water samples.


An accurate method was developed for the determination of Brilliant Blue FCF, a synthetic soluble colorant, in environmental samples. The method is based on the catalytic effect of silver nanoparticles (AgNPs) on the oxidation of Brilliant Blue FCF by hexacyanoferrate(III) in acetate-acetic acid medium at room temperature. Linearity of around four orders in… (More)
