Abstract
Main parameters of the 1-5 diphenylcarbazide standard method for specrophotometrical detection of Cr(VI) metal ions in water were optimized for application on a miniaturized and portable device for continuous monitoring of water pollution. The aim was the reduction of involved volumes, manageable by a microfluidic device, the choice of suitable solvents and acid solutions, the optimization of reagents amounts and the radiation of the sample by a single wavelength visible source. The optimized process was verified on a bench prototype.
