锰是人体必需的微量元素之一,它有许多重要的生理功能;但过量的锰进入人体,会导致中毒,可引起机体多系统的损害。人体所需要的锰,主要来源于食物和饮水。锰是饮用水检测的必检项目之一,我国生活饮用水卫生标准锰的限值为0.1 mg/L。采用火焰原子吸收分光光度法测定水中锰,有时会发现锰的回收率较低。本文通过用火焰原子吸收分光光度法检测计算不同水样 Manganese is one of the essential trace elements of the human body, and it has many important physiological functions; however, excess manganese entering the human body can cause poisoning and can cause multiple system damages. The body needs manganese, mainly from food and drinking water. Manganese is one of the items to be inspected for drinking water. The limit of China’s drinking water standard of health is 0.1 mg / L. Flame atomic absorption spectrophotometry for the determination of manganese in water sometimes found that manganese recovery was low. In this paper, different water samples are calculated by flame atomic absorption spectrometry
