Abstract
Sodalite is characterized by an ordered aluminosilicate framework of AlO4 and SiO4 tetrahedra which involves Na+ and Cl-ions in cubo-octahedral cages.
And sodalite can be synthesized at temperature less than 1000℃. Considering those properties of sodalite, we examined experimentally fixation of iodine and cadmium as sodalite wastes.
Fixation performance of sodalite waste depends strongly upon reaction temperature pattern. In this study, we examined relation between fixation performance and reaction temperature pattern. We employed not PID control algorithm with linear action but sliding mode control algorithm with nonlinear action for reaction temperature control.
