H-Point Standard Addition Method for Simultaneous Determination of Eosin and Erytrosine

A new, simple, sensitive and selective H-point standard addition method (HPSAM) has been developed for resolving binary mixture of food colorants eosin and erythrosine, which show overlapped spectra. The method is based on the complexation of food dyes eosin and erythrosine with Fe(III) complexing...
