摘要： PROBLEM TO BE SOLVED: To obtain useful substances utilizable as the fodder of stock and poultry, the baits of fish and shellfish, foods or the like from the guts of scallops by removing harmful metals such as cadmium therefrom and making the same harmless. SOLUTION: The cadmium removal system for the tissue of of scallop gut includes: a cadmium elution stage (1); a suspended solid removal stage (2); a cadmium-removed aqueous solution preparation stage (3); a cadmium-removed aqueous solution circulation stage (4); and a stage (5) where a solid treated material and a liquid treated material are separately extracted from the final treated material in the stage (1). The dipping conditions in acid, the elution conditions with water and the frequency of the repeat in the stage (1) are controlled so that the content of cadmium based on the dry mass in the final treated material in the stage (1) becomes ≤1 ppm. Thus, amino acid-containing substances having a cadmium content of ≤1 ppm are obtained as the solid treated material and liquid treated material in the stage (5). COPYRIGHT: (C)2005,JPO&NCIPI

解决方案：扇贝肠组织的镉去除系统包括：镉洗脱阶段（1）; 悬浮固体去除阶段（2）; 镉去除水溶液制备阶段（3）; 镉去除水溶液循环阶段（4）; 和阶段（5），其中固体处理材料和液体处理材料在阶段（1）中从最终处理的材料中单独提取。控制酸中的浸渍条件，水的洗脱条件和阶段（1）中重复的频率，使得基于阶段（1）中最终处理材料中的干质量的镉含量变为≤1 PPM。因此，在阶段（5）中，作为固体处理材料和液体处理材料得到镉含量≤1ppm的含氨基酸的物质。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To efficiently remove cadmium in the tissue of the internal organs (hereinafter abbreviated as the tissue) of scallops to the concentration of a reference value of ≤2.5 ppm for feed, preferably ≤0.8 ppm for food by using the minimum amount of an effluent.
SOLUTION: The subject method for removing toxic metals successively performs the following processes: (1) impregnating sufficiently the tissue with an inorganic acid water solution; (2) removing the excess inorganic acid water solution from the tissue impregnated with the inorganic acid; (3) lixiviating the inorganic acid and toxic metals to the outside by bringing the tissue into contact with a water solution of lower concentration than those of the inorganic acid and the toxic metals in the liquid existing in the tissue or into contact with water containing no inorganic acid and toxic metals; (4) removing the excess inorganic acid water solution from the tissue with the lower concentration of toxic metals; (5) lixiviating the inorganic acid contained in the tissue to the outside by adding an alkali water solution for neutralization and further for removal of the toxic metals in the tissue; (6) separating and recovering the tissue from which the toxic metals are removed from the alkali water solution.
