Indigo carmine determining by UV/VIS spectrometric and the kinetic method using Briggs-Rauscher oscillator: two methods comparison
Апстракт
Indigo carmine (InC) is broadly used blue dye in different industrial area. This work aims toobtain analytical curves for determination of InC in aqueous solutions. For such as purposes, twomethods were used: UV/VIS spectrophotometry and the kinetic method based on Briggs-Rauscher (BR) oscillatory reaction, and compared in terms of methods sensitivity whichexpressed as limit of detection (LOD) and limit of quantification (LOQ). To the best authors' knowledge, as candidate for proposed analytical method, the BR oscillatory reaction was appliedfor the first time to InC quantification. The results obtained show that kinetic method using BRoscillatory reaction has a quite lower LOD and LOQ making this method more acceptable todetermine an unknown concentration of InC dissolved in water, compared to UV/Visspectrophotometric method.
