| Abstract: | A method for determination of hexavalent chromium based for flow injection spectrophotometric analysis is reported. It is discussed the possibility of eliminating the turbidity and color by reducibility of ascorbic acid. The method has good linearity, high precision and accuracy. The results are satisfactory when the method is applied for real sample analysis. The method is characterized by simply, rapidly and sensitivity compared to traditional method used with diphenylcarbazide for spectrophotometry. It is suitable for monitoring analysis. |
