The kinetics of thermal decomposition of Sn(II), Pb(II), Cd(II) and Hg(II) alginate gels have been studied using thermogravimetry (TG) and derivative thermogravimetry (DTG) in static air. The thermal dehydration of each gel complex was found to occur in one step, whereas the decomposition of the dehydrated complexes occurred in two steps. The kinetic parameters were computed by different models and...
