A 10–25% solution of sodium hypochlorite is, according to Univar's safety sheet, supplied with synonyms or trade names bleach, Hypo, Everchlor, Chloros, Hispec, Bridos, Bleacol, or Vo-redox 9110. [38] A 12% solution is widely used in waterworks for the chlorination of water, and a 15% solution is more commonly [39] used for disinfection of ...
The OSHA-allowable time-weighted average concentration over eight hours is 10 ppm, [30] almost 140 times higher; The OSHA highest allowable peak concentration (5-minute exposure for five minutes in 4 hours) is 200 ppm, [30] twice as high as the reported highest peak level (from the headspace of a bottle of a sample of bleach plus detergent).
Detergents. A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. [1] There are a large variety of detergents, a common family being the alkylbenzene sulfonates, which are soap-like compounds that are more soluble in hard water, because the polar sulfonate (of detergents) is less likely than the polar carboxylate (of soap) to bind to ...
Typically anhydrous solvents will contain approximately 10 ppm of water and will increase in wetness if they are not properly stored. Organic solutions can be dried using a range of drying agents. Typically following a workup the organic extract is dried using magnesium sulfate or a similar drying agent to remove most remaining water. [5]
On 9 December 2019, New York passed a bill to ban the sale of cosmetics with more than 10 ppm of 1,4-dioxane as of the end of 2022. The law will also prevent the sale of household cleaning and personal care products containing more than 2 ppm of 1,4-dioxane at the end of 2022. [30]
Medical iodophor (Chinese povidone-iodine solution) An iodophor is a preparation containing iodine complexed with a solubilizing agent, such as a surfactant or water-soluble polymers such as povidone (forming povidone-iodine ), [ 1 ] [ 2 ] The result is a water-soluble material that releases free iodine when in solution.
Activated alumina filters can easily reduce fluoride levels from 10 ppm to less than 1 ppm. The amount of fluoride leached from the water being filtered depends on how long the water is actually touching the alumina filter media. Basically, the more alumina in the filter, the less fluoride will be in the final, filtered water.
This group comprises aqueous solution of chlorine, hypochlorite, or hypochlorous acid. Occasionally, chlorine-releasing compounds and their salts are included in this group. Frequently, a concentration of < 1 ppm of available chlorine is sufficient to kill bacteria and viruses, spores and mycobacteria requiring higher concentrations.
