Mori et al reported a highly sensitive spectrophotometric determination of benzoyl peroxide (BPO) based on the color developing reaction between N,N,N',N'-tetramethyl-p-phenylenediamine (TMPD) and BPO in the presence of Ce(IV) in weakly acidic media. In their report, the calibration graph is linear in the range 0-6000 ng BPO per 10 mL with an apparent molar absorptivity of 4.73 E+05 l/(mol cm) at 612 nm. The proposed method is ~50- fold more sensitive than N-ethyl-2-naphthylamine (NENA), and application to assays of flour is described. For detailed procedure, please see their paper. Anal. Lett., 30(13), 2433-2439(English) 1997 Dekker
