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

Waste mid-gut glands of scallop processing was incinerate as industrial wastes since they contained toxic cadmium. However, mid-gut glands is valuable sources for proteins, a fatty substance, docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA). Apparatus of cadmium removal from 20 kg mid-gut glands were assembled by combining the elution of cadmium with malic acid and the adsorption of cadmium with graft adsorbent. After the treatment of 15kg waste mid-gut glands for 24hours by the apparatus, the initial cadmium concentration of 25mg/kg was reduced to 1.0mg/kg.

Removal technology for cadmium ion (Cd) from the mid-gut gland in the scallop processing was developed by combining the Cd leaching process with malic acid solution and Cdadsorption with graft adsorbent. Experimental equipment was assembled for removal of the Cd from 30 kg of mid-gut gland. The concentration of Cd in the mid-gut gland was reduced from 25 mg/kg to 1mg/kg after 24h treatment. The treated mid-gut gland can be used for fertilizer, animal food, food additives, and supplement.
