详情介绍:

    锰,是一种灰白色、硬脆、有光泽的金属,锰广泛存在于自然界中,土壤中含锰0.25%,茶叶、小麦及硬壳果实含锰较多。冶金工业中用来制造特种钢;钢铁生产上用锰钛合金作为去硫剂和去氧剂,锰是正常机体必需的微量元素之一,它构成体内若干种有重要生理作用的酶,正常每天从食物中摄取锰3-9毫克,并为正常骨结构所必需。职业性慢性锰中毒是长期接触锰的烟尘所引起的以神经系统改变为主的病变。早起表现为神经衰弱综合症和植物神经功能紊乱。

    Manganese is a grayish-white, hard-brittle, shiny metal. Manganese is widely found in nature. The soil contains 0.255% manganese. Tea, wheat and hard-shell fruits contain more manganese. Used in the metallurgical industry to manufacture special steel; manganese and titanium alloys are used as desulfurizers and deoxidizers in steel production. Manganese is one of the essential trace elements in normal organisms. It constitutes several kinds of enzymes with important physiological functions in the body. Ingesting 3-9 mg of manganese from food is necessary for normal bone structure. Occupational chronic manganese poisoning is a disease mainly caused by changes in the nervous system caused by long-term exposure to manganese dust. Early onset manifests as neurasthenic syndrome and autonomic dysfunction.

产品原理:

本产品采用分光光度测量方法测定,水样和缓冲剂混合后,在强氧化剂存在下,锰转化成各自的高价态离子,在缓冲溶液和指示剂存在的情况下,高价离子与指示剂反应生成一种带色络合物,分析仪检测此颜色的变化,并把这种变化换算成锰值输出来,生成的带色络合物量相当于锰量。

Product principle:

      This product is measured by spectrophotometry. After mixing water and buffer, manganese is converted into high-valence ions in the presence of strong oxidant. In the presence of buffer solution and indicator, high-valent ions react with indicator. A colored complex, the analyzer detects the change in the color and converts the change into a manganese value output, and the amount of the colored complex formed corresponds to the amount of manganese.
