“…The intermediate species can produce active complexes with Ce(IV). The Ce(IV) complex's decomposition rate is one factor that can influence the kinetics of CL reaction [39, 40]. Ultraviolet–visible (UV‐vis), fluorescence, and CL spectra were obtained in the presence of diphenoxylate to determine the mechanism of CL reaction in the proposed method.…”

In this study, a chemiluminescence (CL) method was developed to determine diphenoxylate in tablets and human plasma. This is the first CL method proposed to determine diphenoxylate. Creating three‐dimensional data caused the parallel factor analysis algorithm (PARAFAC) to be used for the first time in CL methods. The method is based on the fact that diphenoxylate enhances the weak CL produced in the reaction of Ru(phen)32+ and acidic Ce(IV), and the concentration of Ce(IV) solution has a different effect on the CL response of diphenoxylate and the blank plasma. The calibration curve was linear from 4.0 × 10−8 to 1.6 × 10−6 mol L−1 (R2 = 0.9954), and the detection limit was 1.3 × 10−8 mol L−1 (S/N = 3). The sampling rate was about 30 samples per hour, and the % RSD for 10 repeated measurements of 4 × 10−7 mol L−1 diphenoxylate was 5.4%. The interference effects of some ions, amino acids, and common additives were also investigated. The CL method was successfully used to determine diphenoxylate in tablets, and the results were statistically confirmed by the reference method. The proposed CL method and the PARAFAC algorithm were successfully used to determine the concentration of diphenoxylate in human blood plasma samples.
