| Abstract: | Aspectrophotometric method using pararosanitine hydrochloride was established to determine sulfite content in the fermented wine with triethanolamine as absorbent.Maximum absorbance of the product is at 564 nm with absorptivity of 3.6 × 104. The relative standard deviation is 1.99%. The recovery rate ranges from 97.3%to 105.6%. The minimum detectable amount is 0. 16μg(SO2). |
