Abstract

Conflicting evidence has been published concerning the occurrence of an oxidation exothermic peak on differential thermal curves for NH4-saturated clay minerals. The present experiments show that this peak is affected by (a) the clay mineral concerned and (b) the nature of the thermocouple, Pt/PtRh thermocouples apparently acting as good catalysts for oxidation of released ammonia.
