总铁测定试剂盒（专利号：ZL 2007 2 0179093.4）
Iron (total) Test Kit
1, 10-Phenanthroline Method
产品介绍：
铁离子存在比较复杂，可以为二价或三价，也可能是简单水合离子、复杂的无机、有机络合物形式存在。水中的二价铁很容易氧化三价，所以测定总铁含量更有实际意义。铁的主要排放在于选矿、冶炼、机械加工、酸洗废水等。
方法原理：二氮杂菲分光光度法
检测范围：0.05-0.1-0.2-0.3-0.4-0.6-0.8-1mg/L

Iron (total) Test Kit
Background of development
Sources of iron
The mainly sources of iron pollution of water are wastewaters coming from many industries such as ore-dressing, smelting, mechanical processing, industrial plating, pickling. The iron has a variety of existing forms in water samples. It can exist in molecular solution in the form of simple hydrated ions, inorganic or organic complexes, which are either ferrous iron or ferric iron.
Significance of iron (total) test
Ferrous iron in water can be easily oxidized to ferric iron if the water samples exposes to air, therefore, a timely determination of the total iron concentration in water is meaningful.
Iron and its compounds are of low toxicity and micro-toxicity. A high iron content of water often causes a yellow color and iron smell to the water. If this kind of water used in industrials such as printing and dyeing, textile, paper and etc., the quality of the products will be affected by the macula formed on the products.
Principle
The method equals to 1, 10-phenanthroline method (GB/T5750.6-2006). In the presence of appropriate buffer and reducing regents, low valence of iron ions react with 1, 10-phenanthroline to form a stable orange complex, the color depth is proportional to the concentration of iron ions.
Quick and easy
Operating in accordance with the instructions, users can complete the phosphorus test independently without specialized training. 5 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: 0.05～1.0mg/L. If the concentration is out 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 in size, light of weight and easy to carry.
Application areas
This product can be used in analysis of iron in drinking water, surface water, groundwater, wastewater, and etc..
