| 摘 要： | The color reaction of amoxicillin with victoria blue B was studied.A novel visible spectrophotometric method for the determination of amoxicillin has been established.Under pH 8.50～10.5 condition,victoria blue B reacteds with amoxicillin to form red ion association complex.The maximum absorption wavelength was at 630nm and the apparent molar absorptivity(ε) was 2.67×10~4 L·mol~(-1)·cm~(-1) and the linear ranges was 0～5.5 mg·L~(-1).Amoxicillin obey Beer's law in definite concentration range.The optimum reaction conditions and the methodological precision were studied simultaneity.The method was simple and rapid and sensitive for the determination of amoxicillin.This method has been applied to the determination of amoxicillin is in the city sell amoxicillin medicament is in point and average recovery at 98.2%～101.0%.
