Abstract

The present invention discloses iodine replenisher with control released iodine and its preparation process and use. The iodine replenisher is hydrotalcite containing interchangeable iodate radical or iodine ion with iodine content of 0.5-5%. The preparation process includes inserting iodate radical or iodine ion into layers of hydrotalcite; or calcining hydrotalcite at 450-550 deg.c to obtain bimetal oxide and carrying iodate radical or iodine ion to the layered structure of the bimetal oxide. Supporting iodine onto hydrotalcite, which possesses excellent biocompatibility, excellent gastrointestinal mucous membrane affinity, high interlayer interchangeability, high surface activity and great specific surface area, can obtain controlled releasing of iodine and raise utilization of iodine. The control released iodine preparation has low toxicity and high efficiency and may be used as iodine replenisher for human body and animal.

Description

technical field [0001] The invention relates to an iodine replenishing agent of controlled and slow-release iodine, a preparation method and application. Background technique [0002] 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 can be manifested as stunted growth and development, decreased vitality, leading to "cretinism". (3) Affect animal reproductive performance: Iodine deficiency can cause animal reproductive disorders,...
