Abstract:ObjectiveTo establish the method of testing the content of cefepime hydrochloride using fluorescence quenching. MethodsThe fluorescence of SDBS was quenched with the addition of cefepime hydrochloride.The content of cefepime hydrochloride could be calculated though the linear relation between intensity of SDBS and the content of cefepime hydrochloride.ResultsThe analytical results were good.The linear range was 08-100 mg/L.The detection limit was 1.27×10-6g/L.ConclusionThe method was applied to determine the content of cefepime hydrochloride due to its simple,high sensitivity and low detection limit.
