Indigo carmine (InC) is broadly used blue dye in different industrial area. This work aims to obtain analytical curves for determination of InC in aqueous solutions. For such as purposes, two methods were used: UV/VIS spectrophotometry and the kinetic method based on Briggs- Rauscher (BR) oscillatory reaction, and compared in terms of methods sensitivity which expressed 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 applied for the first time to InC quantification. The results obtained show that kinetic method using BR oscillatory reaction has a quite lower LOD and LOQ making this method more acceptable to determine an unknown concentration of InC dissolved in water, compared to UV/Vis spectrophotometric method.
