| Abstract: | The cefazolin can be detected according to the change of solution color resulting from the plasmonic resonance absorption of AuNPs.The absorbance ratio at 520/660 nm of AuNPs is proportional to the concentration of cefazolin in the range of 0.1~5.0 μmol/L with the detection limit of 14 nmol/L.This method could be extended to the determination of cefazolin sodium powder injection,the recovery of cefazolin was in the range of 97.4%~100.2% while the relative standard deviation was less than 6.1%. |
