The recent progress of methods of catalytic kinetics photometric method for determination of trace Cu（ H ） was re- viewed. Nowadays, photometric methods for the determination of Cu mainly include fade catalytic kinetic spectrophotometry, the colour developing catalytic kinetic spectrophotometry, and resistance inhibitory kinetic spectrophotometric method. The development situations of the method were briefed from aspects of reaction systems, the reaction medium, the linearity range, the detection limit and applica- tion. The aims in studying new high sensitivity instructions, looking for new activator, improving the sensitivity reaction monitoring technology are as important as the aims in investigating the reaction mechanism of catalytic kinetic, combining catalytic kinetic spectro- photometry with other analysis technology in the future research direction.
