We have studied aqueous HCN in an heterogeneous phase, with the purpose of
analyzing the effect of a clay mineral, namely Na-montmorillonite, in radio
lysis. The results obtained show that carboxylic acids are formed among the
radiolysis products of HCN. In the presence of clay, the formation of carb
oxylic acids is observed but to a lesser extent than without clay. (C) 2001
