Fluorine Detection Kit, 0-1.5mg/L

Estimated delivery : 30 Days; MOQ : 1 Box ( 1 Box = 50 Times)
The rapid test series is a semi-quantitative test product. The test results are interval values, so there is no concept of precision or accuracy. The sensitivity is the minimum detection limit.
Widely used in rapid on-site detection of water quality in urban water supply, food and beverage, environment, medical, chemical, pharmaceutical, thermal power, papermaking, breeding, bioengineering, fermentation technology, textile printing and dyeing, petrochemical, water treatment and other fields

Basic features:

1. Ability to detect indicators and read data in a relatively short time
2. Simple operation, no other accessories required
3. Easy to carry, suitable for on-site testing
4. Cheap

Instructions :
Take a clean colorimetric tube and add the water sample to the scale line of the tube ( 10mL), add a pack of fluorine reagent (I), shake until completely dissolved, then add 1mL of fluorine reagent (II), shake until completely dissolved, leave it for 5 minutes, lift the tube to a blank place about 2 cm above the color card and compare the color with the standard color scale from top to bottom. The color scale with the same color tone as the solution in the tube is the fluorine content in the water (mg/L)

Note:

1. The pH of the sample solution should be 4-7
2. The presence of 0.2 times the concentration of AI 3+ , Zn 2+ , Ni 2+ , Co 2+ , or 1 times the concentration of Fe 3+ , Pb 2+ in the sample solution will interfere with the determination. A large amount of anions such as chloride and sulfate can also cause interference.

Note:

1. The pH of the sample solution should be 4-7
2. The presence of 0.2 times the concentration of Al 3+ , Zn 2+ , Ni 2+ , Co 2+ , or 1 times the concentration of Fe 3+ , Pb 2+ in the sample solution will interfere with the determination. A large amount of anions such as fluoride and nitrate can also cause interference.
3. The liquid to be tested must be colorless or light-colored. Colored liquids must be decolorized before testing (solution decolorization: activated carbon adsorption method or dilution method)
4. If the liquid to be tested is turbid, let it stand for a while and then take the clear part for testing.
5. The color comparison must be completed within the specified time. If the test result exceeds the specified time, it will be invalid.
6. If the concentration of the liquid to be tested exceeds the detection range, dilute it with distilled water before testing.
