A model for the system design and optimum operation control of our system for removing cadmium from squid viscera by means of the competitive adsorption method is proposed. The adsorption and desorption data of cadmium on chelating resin and squid viscera fit an ion exchange model. However, in the competitive adsorption process, the cadmium adsorption constant of the chelating resin was significantly lowered by divalent metals contained in squid viscera. The competitive adsorption model was derived by correcting the cadmium adsorption constant as a function of the solid concentration of squid viscera. The model could determine the optimum dosage of chelating resin corresponding to the cadmium content and water content of squid viscera.
