ConclusionThe analysis <strong>of</strong> methylene blue reduction <strong>by</strong> ascorbic acidis performed quickly and easily with the Evolution Arrayand VISIONcollect s<strong>of</strong>tware. In this experiment, rate datawas obtained for the analysis and rate constants weresimultaneously calculated using the kinetic analysis function<strong>of</strong> the VISIONcollect s<strong>of</strong>tware. The export function <strong>of</strong> theVISIONcollect s<strong>of</strong>tware facilitates further data processingin EXCEL ® . From this analysis it was determined that therate constant <strong>of</strong> the reaction is dependent on theconcentration <strong>of</strong> both ascorbic acid and HCl and not onthe initial concentration <strong>of</strong> methylene blue.References1.
