Cephalosporins are widely used as veterinary and human antibiotics.However,cephalosporin abuse is harmful to human health and causes allergic reactions or antibiotic resistance.We investigate a method featuring Raman spectroscopy and chemometrics to quantify mixture solutions of three typical cephalosporins,namely,ceftriaxone,cefotaxime sodium,and cefazolin sodium.Partial least-squares regression models are built on spectral data that are preprocessed by various methods.With prediction relative errors within5%and high correlation coefficients of 0.998,we demonstrate that Raman spectroscopy combined with multivariate analysis is feasible for use in the quantitative determination of cephalosporin solutions.
