✦ Synopsis

Both methods showed excellent agreement, with a maximum deviation of _+5%. Only at unusually high concentrations of some potential atmospheric species could slight interferences be observed. During the experiments the detection limits were 1.3 Γ— 10 -8 mol/l (0.44 ppbm) of H202 for the fluorometric instrument and 4 Γ— l0 -~ mol/1 (1.36 ppbm) of H202 for the chemiluminescence instrument. For the chemiluminescence technique, the response to methylhydroperoxide was approximately 80-fold less than that to an equivalent concentration of H 2 02.

## Abstract Based on the chemiluminescence (CL) intensity generated from the potassium ferricyanide [K~3~Fe(CN)~6~]–rhodamine 6G system in sodium hydroxide (NaOH) medium, a new sensitive flow‐injection chemiluminescence (FI–CL) method has been developed, validated and applied for the determination
