[Research development of catalytic-kinetic spectrophotometric method for the determination of trace amounts of copper].

A review on the recent research progress in the determination of trace amount of copper with catalytic-kinetic spectrophotometric method is presented and discussed. First, by comparison it is showed that catalytic-kinetic spectrophotometry has more advantages than atomic absorption spectrophotometry and extraction spectrophotometry for the determination of trace amounts of copper. Then the basic theory of catalytic-kinetic spectrophotometry is introduced. The review and discussion on the recent research developments in catalytic discoloring spectrophotometry, catalytic coloring spectrophotometry and catalytic fluorescence spectrophotometry for the determination of trace amounts of copper are given. Finally the development trends and application perspectives of the catalytic-kinetic spectrophotometry are discussed and probed. 29 references are cited.
