Abstract

A slow-release I-supplement used as the I-supplementing additive of forage or to prepare I-supplementing food or medicine for treating diseases is an anionic exchange resin containing the iodic acid radicals or I ions. It is prepared through the ionic exchange between iodic acid radicals or I ions and anionic exchange resin.

Description

technical field [0001] The invention relates to a slow-release iodine supplement, a preparation method and application. Background technique [0002] Iodine is an essential component of the thyroid. Its biochemical functions are mainly expressed through thyroid hormones, and its biological effects on the body are extremely extensive. According to the latest "Catalogue of Allowed Feed Additives" promulgated by my country, the trace element compounds that can be used to supplement iodine in livestock and poultry include potassium iodide, potassium iodate and calcium iodate. Other iodine-containing compounds include sodium iodide, ethylenediamine dihydroiodide, cuprous iodide, 3,5-diiodosalicylic acid, and thymol iodine. Potassium iodide and sodium iodide have poor stability and are easily oxidized by oxygen in the air and other trace elements in the feed, resulting in a decrease in their biological activity or even a complete loss. In addition, when potassium iodide is comp...
