Colorimetric determination of food colourants using solid phase extraction into polymethacrylate matrix
This paper describes a simple colorimetric method for determination of Brilliant Blue, Sunset Yellow, Ponceau 4R and Tartrazine using transparent polymer optode. The method provided acceptable linear ranges 0.01-3.0 mg L −1 with correlation coefficients higher than 0.995 under the optimal conditions...
