铜是生命机体中不可缺少的微量元素之一,参与酶催化功能,也是人体血液、肝脏和脑组织等铜蛋白的组成部分。缺铜会引起贫血,但摄取过量又会引起肝脏等器官损害。铜广泛分布于动物、植物组织以及环境水体中,同时,铜也是工业上广泛应用的金属,因此环境及生命组织中痕量铜的测定日益引起人们的重视。 Copper is one of the indispensable trace elements in the body of life and participates in the function of enzyme catalysis. It is also an integral part of the human body’s copper, such as blood, liver and brain tissues. Copper deficiency can cause anemia, but excessive intake can cause liver and other organ damage. Copper is widely distributed in animals, plant tissues and environmental water. At the same time, copper is also a widely used metal in industry. Therefore, the determination of trace copper in environment and living tissues has drawn increasing attention.
