| Abstract: | The method for the determination of the nitrate content in fresh vegetable by ultraviolet spectrophotometry is set up. The result of determination has no significant difference in comparison with the spectrophotometric method with phenol disulfonic acid by t - test. RSD is smaller than 4.5% , This method is suitable for the determination of the different content nitrate in fresh vegetable. |
