Abstract

An iodine supplement used for the forage of animals and fowls and human health-care food or medicine is a hydrotalcite carried molecular iodine. It is prepared through providing hydrotalcite as micro reactor and reducing or oxidizing reaction to reduce iodic acid (or iodate) or oxidize iodide to obtain molecular iodine.

Description

technical field [0001] The invention relates to an iodine replenishing agent for loaded molecular iodine, a preparation method and application thereof, in particular to an iodine replenishing agent for molecular iodine supported by hydrotalcite, a preparation method and an application. Background technique [0002] 1. Application of iodine in animal husbandry production [0003] Iodine is an essential component of the thyroid. Its biochemical functions are mainly manifested by thyroid hormones, and it has a wide range of biological effects on the body, mainly including: (1) Regulating metabolism and maintaining heat balance in the body. (2) Affect the growth and development of animals: Iodine has a regulatory effect on the development of the central nervous system, skeletal system, cardiovascular system and digestive system, and can promote tissue differentiation and growth, thereby promoting the growth and development of young animals. Iodine deficiency in young animals c...
