Simultaneous 2nd Order Derivative Spectrophotometry Determination of Sorbic and Benzoic Acids in Soft Drinks |
|
| Abstract: | Abstract A method is developed for the simultaneous 2nd order spectrophotometric determination of 1 to 7 μg.mL?1 of each of benzoic and sorbic acids in non vegetal soft drinks, using a blank prepared from the same soft drink to be analyzed in order to avoid the interferece from other additives and colouring matter present. |
