Solid phase spectrophotometry is a new, simple, fast and sensitive trace analytical method. In this report, it is presented a method that the polyamide was used for the absorbence and the reflectances absorbances were measured directly with remodelled the colorimetric cell. Not only the trace inorganic ion can be analysed by the solid phase method, but also the artificial synthetic pigment in the drug can be determined, the results are satisfied.
