近年来,微量元素与人体健康的研究日益受到重视,而钙作为人体的必需元素之一,对人体有多方面的作用。因此,了解人体内钙含量就成了了解天体生长代谢情况的一个重要指标,而血液和头发作为人体的重要部分是医学常用检测的生物材料。新钙试剂对羧基偶氮羧与目前常用的钙试剂相比,具有灵敏度高,选择性好等优点,是测定钙的优良显色剂,其结构式为:
In recent years, the research of trace elements and human health has been paid more and more attention, and calcium, as one of the essential elements of the human body, has many functions to the human body. Therefore, knowing the calcium content in the human body becomes an important indicator for understanding the growth and metabolism of celestial bodies. Blood and hair as an important part of the human body are commonly used in medical detection of biological materials. Compared with the commonly used calcium reagents, the new calcium reagent has the advantages of high sensitivity and good selectivity, and is an excellent color reagent for measuring calcium. Its structural formula is as follows:
