| Abstract: | Assay of aminopyrine in co - preparations by ion - pair extraction spectrophotometry was reported.Aminopyrine in co-preparations formed a stable ion-pair with bromocresol green in pH 3. 6 buffer solution.The ion-pair was extracted with cholorform, then determinated at wavelength 416.8nm.The average recoveries and relative standard deviation were 99.80%,0.92% respectively.This method is rapid, simple and precise. |
