Common Uses Of Peroxide Test Strips
Peroxide test strips are used in organic and inorganic compounds containing peroxide or a hydroperoxide group. It is suitable for the routine check for simple ethers such as dioxin, diethyl ether, diethyl ether (ether) and tetrahydrofuran.
Peroxide test strips are commonly used for testing water for peroxide in spas, hot tubs and swimming pools.
Polymeric peroxides sometimes occur in food products and are hard to detect. Therefore, it is advisable to decide in the laboratory that the peroxide test strips give satisfactory results.
In addition to checking the product, this product can be used for testing:
- Residual UHT milk peroxide
- Perborate calibration in washing powders
- To check electrolytic etching
- Stripping copper baths
- To test used peroxide as a bleaching
- Stripping copper baths
- Oxidation in the production of paper and textiles
- To determine peroxides in pool water
Peroxide is an excellent bactericidal, fungicidal and virucidal. It produces no harmful decomposition products. With these characteristics, it is a versatile disinfectant. This makes it suitable peroxide for use in the food industry.
In this case, examination of peroxide can be used to control the concentration of the disinfectant. It is also good for the detection of residues present in the apparatus after cleaning and rinsing.
Use in organic solvents
It's generally recognised that ether peroxides are dangerous. However, the risk is often underestimated. When distilled ethers can lead to an explosion that could be avoided.
Explosions can also occur when liquid containers containing peroxide or peroxides shake swell due to friction at the opening. This type of risk is present not only in ethers such as diisopropyl ether. Diethyl ether, tetrahydrofuran and dioxane or other liquids with a tendency to form peroxides are also a risk.
Salts contains an unsaturated, ketones, hydrocarbons, tetralin and, aldehydes can also be tested. To prevent accidents, and the liquid must be tested for peroxides at regular intervals and again before use. Peroxide test is useful for fast, reliable and semi-quantitative control of the presence of hydroperoxide and peroxide ether.
Therefore, it is ideal as a routine test for simple ethers such as diethyl ether, dioxan and tetrahydrofuran. Polymeric peroxides, which occasionally form in diethyl ether, are undetectable.
The peroxides don't react or significantly reduces the sensitivity of:
- Tert-butyl perbenzoate
- Dicumyl peroxide
- Di-tert-butyl
- 1, 3-cyclooctadiene
In these cases, a preliminary test is recommended. This is because the change in the test conditions sometimes allows a reproducible result. It can at least are present as a quantitative indicator of the peroxide.
The samples must be analysed at the same time in the laboratory. This is to verify the appropriateness of test strips for the intended particular test. Also, you must pay close attention to the expiry date for the test.
