锰测定试剂盒
Manganese Test Kit
Potassium Periodate Method
产品介绍：
环境水源中通常含有一定的金属离子，其中一部是自然存在于水体中，还有一部分是人为的排放在水源中。锰的价态较多，锰也是生物体必需的微量无素之一，在环境水样的锰一般为数微克／升或数百微克／升，很少有超过1mg/升，但是由于矿山、冶金、化工等工业排放的污水可以使得环境中的锰含量增加。
原理方法：国标高锰酸钾氧化法
检测范围：0.1-0.5-1-2-5-10mg/L

Manganese Test Kit
Background of development
Sources of manganese
There are many valence states of manganese compounds, mainly divalent, trivalent, tetravalent, hexavalent and heptavalent manganese. Manganese is one of the essential trace elements of organisms. Manganese exists in groundwater in form of soluble divalent manganese because the lack of oxygen. While in surface water, manganese is in forms of soluble trivalent complexes and tetravalent manganese suspensions. The content of manganese in the environment water samples is between few μg/L to several hundreds μg/L and rarely more than mg/L. The main pollution sources of manganese are waste waters discharged from black metal mine, metallurgy and chemical industries.
The significance of manganese test
Manganese salt is of low toxicity, but excessive levels of manganese in water makes the ugly manganese stains are left to clothing, textiles and papers. Therefore, in general the manganese content of industrial water is not allowed to be more than 0.1mg/L.
Principle
This method equals to potassium periodate oxidation method (GB11906-1989), in the presence of potassium pyrophosphate - sodium acetate, low valence manganese will be oxidized to permanganate salt instantly by potassium periodate at room temperature, and the color is stable for a long time.
Quick and easy
Operating in accordance with the instructions, users can complete the manganese test independently without specialized training. 10 minutes is enough to complete the analysis of one water sample.
Accurate and reliable
Determination results with this method are in accordance with the results with the standard method. It can be used as an alternative method to the standard method.
The range of the determination: 0.1～10mg/L. If the concentration is out of the range, please repeat the operation after appropriate dilution of the water sample.
Quantitative packing
The kit can be used for 50 times. It is small, light and easy to carry.
Application areas
This product can be used in analysis of manganese in drinking water, surface water, groundwater, wastewater, and etc..
