Abstract : The clay colloidal of soil can be predicted to have a large influence on the fate of hydrazines in the soil environment. Initial degradation microcalorimetric studies have shown that this influence arises mainly through the processes of sorption and degradation. Clay minerals can reversibly sorb hydrazine, and a certain amount of strong irreversibly sorption can also occur. The colloidal clay components catalyze the degradation of the hydrazine, and in some instances cause very rapid and vigorous degradation. The two main factors which influence hydrazine sorption and degradation are the pH values of the solutions, and the exchangeable metal cations held by the clay.
