| Abstract: | In present paper, derivative spectrum of zero to fourth lanthanum - xylenol orange (XO)and lanthanum - xylenol orange - cetylpyridinium chloride(CPC)systems have been studieds,and optimum instrumnetal parameters also have been given. The results shows: La - XOsystem may have baan used in analytical determination at pH 4.00~6.00 and pH > 8. 00,ithave not absorption spectrum at pH 7.00~8.00; La - XO - CPC system may have been usedin analytical detdrmination at all of pH range in which has been studied in this paper. |
