Abstract: Three simple and sensitive methods for the determination of Ampicillin are described. ... more Abstract: Three simple and sensitive methods for the determination of Ampicillin are
described. The first method is based on investigation of the oxidation reaction of the drug with alkaline potassium dichromate for a fixed time of 70 min., where sodium hydroxide used as an alkaline media. The absorbance of the colored dichromate ions is measured at 369 nm.
The second method is based on the oxidation reaction of Ampicillin with acidic potassium dichromate. Spectrophotometric measurement was achieved by recording the absorbance at 340 nm for a fixed time of 70 min., where sulfuric acid used as an acidic media. The third method is based on the oxidation reaction of Ampicillin with alkaline hydrogen peroxide; the absorbance is measured at 302nm for a fixed time of 70 min., all procedures were achieved at room temperature.
All variables that affecting the procedures were investigated and the conditions were
optimized. Calibration graphs were constructed; mean and standard deviation were
calculated.
