Development of a new method based on scanner electrochemistry: applied for the speciation of Iron(ii) and Iron(iii)

Abstract

A new, simple and inexpensive method was developed based on scanner electrochemistry as an appropriate alternative to visible spectroelectrochemistry. The electrochemical cell containing the sample solution was scanned by a flatbed scanner and color values were analyzed by software in the RGB color system. The validity of this new method was studied by speciation of iron(II) and (III). The speciation was performed by complexation of iron species with SCN⁻. Parameters, such as time and potential of electrolysis, which affect the system were optimized.
