The development of spectrophotometric analysis of hexavalent chromium from 2000 to 2007 is reviewed. Main analysis methods include conventional photometric method, catalytic spectrophotometric method and inhibition kinetic spectrophotometric method. The indicator reaction, detection limit, linear range and applications of the methods are involved. The development tend for spectrophotometric determination of hexavalent chromium in the future is discussed. Finally, we give some suggestions for the development of spectrophotometric analysis. Improving the performance of equipment to increase sensitivity and reduce the measurement error, exploiting the new colored dyes and indicators with high sensitivity, selectivity, stability and low toxicity, associating the good separation and enrichment technology with high automation, Sensitivity, stability with the detection method to reduce determination interference and enhance the accuracy of the methods should be noted.
