Hydrogen peroxide-sodium hydrosulfite chemiluminescence system combined with high-performance liquid chromatography for determination of 1-hydroxypyrene in airborne particulates

► NaHSO3-H2O2 chemiluminescence system was developed for determination of 1-hydroxypyrene in airborne particulates for the first time. ► The chemiluminescence method showed higher sensitive than the previous method. ► 1-Hydroxypyrene was successfully detected in Kanazawa airborne particulates by the proposed chemiluminescence method. ► Possible mechanism of this chemiluminescence reaction was also proposed.
