Background:Iron is abundantly distributed over the surface of the globe. It enters the water body through circulation under particular environment conditions. Human activities, such as ore dressing, smelting, machining, plating, acid washing and other industry practices, can also produce large amount of iron-containing waste water. The presence of iron in water can be in various forms. It may exist in solution as simple hydrated ion, or as complex compound whether organic or inorganic; It can be either bivalent or trivalent. Although trace amount of iron is innocuous, it may cause harm to drinking water and industry production when its content is over certain level. Water of high iron content tend to appear a yellowish color and taste fishy when used for drinking; when used for printing and dyeing, textile, paper and other industry purpose, it may form yellow spot on the surface of the products, undermining the quality; when used as circulation water, it may deposit in the pipe as scale, or cause the failure of ion exchange resin. Therefore, it is highly necessary to control and test the water total iron  content. As the traditional test method for water total iron content is complicated, the R&D team of Thaile Chemical has successfully developed “Thaile” total iron test kit for quick on-spot testing. The new test kit can greatly simplify the operation and significantly lower the testing cost with reliable testing result
Principle:Testing based on national standard.
Purpose:Quick and accurate test of water total iron content. On-spot quick test in various water consumption field, including industry, agriculture, aquiculture, healthcare, environment and domestic.
Features:
1.Quick and easy:No special training is required, as long as the user follows the instruction. It takes only 10 minutes to finish a test for one water sample.
2.Accurate and reliable:With test results equivalent to what national standard suggests, it is an alternative of the method introduced in the national standard.
3.Highly sensitive:The reagent is highly sensitive to iron, with precision as high as 0.05mg/L.
4.Affordable: Cost per test is low.
5.Portable:Compact in size, lightweight, and suitable for on-spot quick test.
Operation:
1.Wash the colorimetric tube twice with water sample. Then, measure and take certain amount of water using the colorimetric tube. Adjust the level to the graduation mark of 15ml using a plastic dropper.
2. Drip 20 drops of Reagent Ⅰ into the colorimetric tube and shake up.
3. Then add 1 flat ladle (use the colorimetric card to cut the powder so that it levels with the rim of the ladle) of Reagent II into the colorimetric tube, and agitate the solution to make the powder dissove in the solution.
4. Then start colorimetric test after waiting 5 minutes. Vertically place the colorimetric tube 1cm above the blank area of the colormetric card and visually compare the colors from above. Read the total iron content of the water sample by finding the color code that appear the same color as that of the liquid in the tube.
Notes:
1.This product has a detectable total iron content range of 0.05-1.0mg/L. If the total iron content of the water sample is higher than the upper limite of the detectable range , dilute the water sample before testing.The actual result is obtained by timing the reading with corresponding dilution ratio.
2.If there are agglomerations in the powder, smash them with the ladle before using it. As the reagent is in excessive amount, small amount variation each time after cutting flat the powder will not affect the test result
3.If the water sample appear turbid, filter the sample , or stand the sample until it is clear, then take sample from the upper part, before testing.
4.Try to compare the colors in bright light.
5.The plastics droppers are used only for adjusting the water volume when measuring and taking the water , not for dripping the reagent. The above mentioned “drops” of reagent I represent the drops squized from the reagent bottle.
6.In case of skin or eye contact of the reagent, just wash it away with water. As reagent I is subacid, keep it away from body.
7.After use, please tighten the cap to avoid ineffectiveness. 
Liability: The manufacturer and its authorized agents are free from any liabilities due to accidental intake of children and misunderstanding or misuse of the users. If the results of test are dubious, please present the sample to authoritative laboratory for further test.
