Abstract

The invention discloses a cadmium removing adsorbent for marine products and a preparation method of the cadmium removing adsorbent. The cadmium removing adsorbent for the marine products is preparedfrom the following raw materials in part by weight: 20-30 parts of modified silica powder, 50-70 parts of fish bone meal, 25-50 parts of modified shell powder, 15-30 parts of shrimp shell powder, 10-30 parts of a complexing agent, 3-5 parts of sodium carbonate and 200-400 parts of a solvent. The invention further provides the preparation method of the cadmium removing adsorbent for the marine products. The method comprises the following steps: mixing the raw materials, drying the raw materials at 70-90 DEG C and grinding the raw materials into 30-50 meshes after drying. When the prepared cadmium removing adsorbent for the marine products is used for removing cadmium from the marine products, the marine products are not needed to be ground, and the cadmium removing rate is high; besides, daily domestic wastes such as shells, fish bones, shrimp shells and the like are recycled and turned into valuables, which is good for environmental protection and reduces the cost; meanwhile, the adsorbent has a certain removal effect on arsenic while effectively adsorbing cadmium.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a cadmium-removing adsorbent for seafood and a preparation method thereof. Background technique [0002] Foodborne illness and food contamination is a huge and expanding worldwide public health problem. Regardless of advanced or backward production methods, there are risk factors that cause food insecurity. In particular, the continuous adoption of new technologies and new raw materials in the field of food production has made food contamination factors increasingly complicated. Major food safety incidents caused by lead, cadmium, and methylmercury pollution in food are not uncommon, especially the heavy metal pollution in seafood is worthy of our deep thinking. [0003] Heavy metals refer to metal elements with a density above 5.0. In terms of environmental pollution, heavy metals refer to mercury, cadmium, lead, chromium and metalloid arsenic with signific...
