ABSTRACT = {The demineralization kinetics of deproteinized lobster shells using CO<sub>2</sub>
 were studied. Demineralization 
reaction proceeds until the concentration of Ca<sup>+2</sup> in solution reaches an equilibrium value. The introduction of 
a cation exchange resin (cationite), in an open system for CO<sub>2</sub>
, allows replacement of the solution Ca<sup>2+</sup> ions by 
Na<sup>+</sup> ions, whereby the equilibrium shifts and an effective dissolution of the exoskeletons’ calcite is achieved. 
The mathematical relationships between the conductivity of the solution and the concentrations of major 
ions, the rate constants and kinetic parameters of the reaction in the absence and presence of the resin were 
obtained. It was found that the reaction follows pseudo-fi rst-order kinetics, and the experimental results were 
in good agreement with the proposed mathematical model.},
