| Abstract: | In this paper a new method of using first order derivative spectrophotometry to determine the trace aluminium content in the solution of coloring trough for aluminium products has been suggested The results indicate that in the presence of OP emulsifier at pH5 0-7 0 Al with CAS can form a stable complex,the maximum absorbance is at 633.0nm,It shows that the selectivity is increased by derivative spectrophotometry The results were proved to be satisfactory when such method was applied to determine trace aluminium in the entitled solution. |
