【Abstract】 A differential kinetic method with the Kalman filter for the simultaneous determination of iron, nickel and copper based on the reaction with 3,5-diBr-PADAP is described. A microcomputer-based FIA stopped-flow spectrophotometric instrumentation system for the determination is designed. This method is used to determine iron, nickel and copper in several aluminium alloy samples with satisfactory results.更多还原
