The RP-HPLC method based on the CL reaction of luminol (124) catalyzed by Co(II) (Section in.B.2.c) can be applied for determination of peroxycarboxylic acids, esters and diacyl peroxides (see examples of LOD in equation 67, Section V.B.2.c) . The biosensor prepared according to equation 70, that is effective in the determination of hydroperoxides (Section V.B.6.b), becomes deactivated after three days of operation when trying to determine t-butyl peracetate. ... 

One such scheme involved the termination of the "living" particle with oxygen to give the lithium salt of styryl hydroperoxide. This salt was converted to the hydroperoxide by neutralization with acetic acid or to the peracetate by reaction with acetyl chloride. The yield of hydroperoxide was determined by titration of a slurry of the particles with iodine-thiosulfate. Figure 15 shows that at low temperatures essentially all of the carbanions are converted to hydroperoxide.
