| titleOfInvention | Photocatalytic method of producing hydroxyl radicals in water |
| abstract | The subject of the application is a photocatalytic method of producing hydroxyl radicals in water, intended in particular for marking substances contained in it. In this method, a base, preferably sodium hydroxide NaOH or potassium hydroxide KOH, is dissolved in pure water or water containing material to be hydroxylated in an amount to obtain an alkaline solution with a pH> 7.0. The light absorbing substance in the form of methylene blue MB is then dissolved in this solution in such an amount that the MB concentration in the solution is from CMB = 1.0 x 10-6 M (mol / liter) to 1.0 x 10-3 M. Then the solution is illuminated with light with a wavelength in the range of? - 200 ÷ 750 nm. Illumination of the solution can be carried out using red wavelength? = 550 ÷ 750 nm, preferably laser light above 1.0 mW, for at least one second. Illumination of the solution can also be carried out using white or ultraviolet light with a continuous spectral distribution in the range? = 200 ÷ 750 nm, power greater than 1 mW for at least 50 seconds. |
