Abstract: The hydroperoxyl radical (HO[SUB2]) is one of the most abundant free radicals in the atmosphere, where in participates in a series of photochemical reactions that determine the late of natural and anthropogenic emissions. In addition, HO[SUB2] is found in droplets and surface water as a result of photochemical formation and gasphase scavenging. We describe a quantitative method for determining trace concentrations of HO[SUB2] radicals that exploits the chemiluminescence produced upon reaction with a synthetic analogue of luciferin from the crustacean Cypridina. The technique is linear at least up to 1 μM HO[SUB2](aq) and has a minimum detection limit of 0.1 nM. A unique feature of this analysis is a calibration method using stable aqueous HO[SUB2] stand ands produced in submicromolar concentrations using [SUP60]Co γ-radiolysis. The advantage of this method in comparison to others in consideration of field deployment is its simplicity, low cost, and minimal size and power requirements. One intended applicafion of this technique is the measurement of atmospheric HO[SUB2] radicals following collection into aqueous solution. [ABSTRACT FROM AUTHOR]
