Study on Measurement of Chromium Content in Ramie through UV Spectrophotometry


Article Preview

In this paper, UV spectrophotometry was used to test the chromium content of bast fiber of ramie and diphenylcarbazide (DPC) was used as color reagent. The optimal technology was: dropping volume of phosphoric acid 0.4~0.6 mL, DPC content 2.0~4.0 mL and coloration time 5-10 minutes. The results showed that complexes were formed from Cr (VI) ions and DPC under phosphoric acid condition. There was a maximum positive absorption peak at the 540nm. Cr (VI) concentration (in the range of 0.004~1.000 mgL-1) and the absorbance (A) of complex obeyed the Lambert-Beer law.
