Abstract
Kinetics of thermal dehydration of synthetic hydroxide hydrogel of chr omium, manganese and cobalt were studied in the temperature range 70 - 450-degrees. The kinetic data and activation energies were different for different stages of dehydration. Activation energy increased progr essively with DTA peak temperature in case of all the hydroxide hydrog els.
