Abstract

Differential pulse voltammetry was used to detect 10 ppb NO2- in fused alkali metal nitrates. The technique was employed for studying the thermal decompn. kinetics of KNO3 and NaNO3 melts under O at 510-620 K. A pseudo-zero-order process was found, characterized by a kinetic const. of 7.6  10-11 mol/kg/s at 538 K and by an apparent activation energy of 39 kJ/mol. A mechanism of NO3- decompn. is proposed, and the equil. const. and H value for the reaction are calcd. and compared with literature data.
