“…The reaction of NO 2 with Griess type reagents has also been investigated by Huygen [58]. Atmospheric NO 2 was also trapped using an alkaline solution and determined spectrophotometrically using a modified version of the Saltzman procedure as well as spectrofluorometrically using 5AF in HCl acid solution [59], with both methods having produced comparable concentrations for atmospheric NO 2 of the order of 1 ppbv [59].…”

“…31 Modifications to the Jacobs-Hochheiser procedure have been proposed. Axelrod et al, 32 suggested the determination of nitrite by fluOrometric analysis with 5-aminofluorescein, This method increased analytical sensitivity substantially, allowing measurement of NO 2 levels as low as 0.01 ppb. These authors, however, explicitly ignored the problem of variable stoichiometry and collection efficiency.…”

“…A number of methods for the determination of NO2(g) in air by use of spectrophotometric [1 and 2], fluorometric [3], chemiluminescent [4], and electrochemical [5], detection have been reported. These methods require trapping and preconcentration of NO2 as nitrite, a process with unreliable stoichiometry [6], and are.either time consuming, or use expensive instrumentation.…”

A number of methods for the determination of NO2(g) The determination is based on the NO oxidation of tris 1,10-phenanthroline)-iron (I I) [ferroin] to its iron(III) analogue at a gas-liquid interface. Two continuous-flow manifolds for sample processing are described and compared. One incorporates a gas diffusion step in which a gas-permeable membrane separates a donor (sampling) stream from an acceptor (detecting) stream.Some of the air sample containing NO diffuses across the membrane into the detecting stream and there causes ferroin oxidation. In the other manifold, the NO-air sample is directly intercalated into the ferroin-containing liquid carrier; oxidation occurs at the gas-liquid interface. The extent of ferroin oxidation is amperometrically monitored at a carbon paste electrode and is proportional to the NO2 concentration in the air sample. The ferroin/ferriin redox couple is a reversible electrochemical system in which oxidation/reduction occurs without affecting the chemical structure of the 1,10-phenanthroline ligand. Some information on the electrochemistry of the ferroin/ferriin couple can be found in the literature [7]. An advantage of the reversibility of this redox process is that the ferriin produced during the oxidation with NO can be electrochemically reduced back to ferroin in a reagent reservoir and thereby can be used in a closed-loop system [8]. A similar direct intercalation procedure for the determination of SO2(g) has been reported [8,9] in which SO2(g) reduces di--hydroxo-bis[bis(1,10-phenanthroline)iron(III)] at a gas-liquid interface. The product of the reduction, ferroin, can be photometrically monitored at 510 nm [8] or amperometically at 965 mV (versus an Ag/AgC1 reference electrode) [9].
