| Abstract: | The derivative spectrum behaviour of scandium-chromazurols system was studied in thepresence of mixed surfaetants, in this paper.The wide-band background caused by coexist-ing ions can be eliminated by third-order derivative spectrometry and microamount-scandium-in some alloys can be determined with satisfied results. |
