A kinetic method for the simultaneous determination of iron, titanium and vanadium is proposed based on their inductive effects on the chromium(VI)-iodide-starch reaction in weakly acidic medium. The reaction was monitored with the stopped-flow spectrophotometric technique. The calibration graphs ar

β¦ Synopsis
A simple stopped-flow/continuous flow method is introduced to acquire kinetics information and to make kinetic determinations. The technique uses a photometric detector placed within the sample loop of a stopped-flow/continuous flow system. Several different carrier streams (aqueous fluids, organic solvents and air bubbles) were investigated. The analytical performance of the system is illustrated with the enzymatic determination of glucose in wine and serum samples.
