Removal technology for cadmium ion (Cd $^{2+}$ ) from the mid-gut gland in the scallop processing was developed by combining the Cd $^{2+}$ leaching process with malic acid solution and Cd $^{2+}$ adsorption with iminodiacetic acid adsorbent synthesized with radiation-induced graft polymerization. Experimental equipment was assembled for removal of the Cd $^{2+}$ from 20-40 kg of mid-gut gland. The Cd $^{2+}$ in the mid-gut gland was reduced from 25 mg/kg to 1 mg/kg after 24 h treatment.
