| Abstract: | A second-order derivative ultraviolet spectrometric method was developed fordetermination of salicylic acid in aspirin.The sample was extracted with dehydrated ether,the organic layer was evaporated to dryness,the residue was dissolved in dehydrated alcoholand scanned in the range of 190-400urn,determined the content of salicylic acid at 326um.This method is rapid and easy to handle with a conventional extraction procedure and satisfactory sensitivity. |
