摘要

use: in the analytical chemistry of water.the essence of the u0438u0437u043eu0431u0440u0435u0442u0435u043du0438u00a0: u0430u043du0430u043bu0438u0437u0438u0440u0443u0435u043cu0443u044e sample water is wiped with alcohol composition of the ci - ei, u0430u043bu0438u043au0432u043eu0442u0443 solution to process the same alcohol in u0441u043eu043eu0442u043du043e to u043du043fu0430u0432 mass (mg) and the amount of alcohol (cc), equal (0.05 to 0.20): (2.00 3.00), then the solution of iodine u0431u0430u0440u0438u00a0 activated chloride, distilled water, mix, working there,mix and u0438u0437u043cu0435u0440u00a0u044eu0442 optical density of the solution and then calculate the u0441u043eu0434u0435u0440u0436u0430u043du0438u00a0 u043du043fu0430u0432 u043eu0442u043du043eu0441u0438u0442u0435u043bu044cu043du0430u00a0 error method u00b14,5%, u0432u0440u0435u043cu00a0 u043eu043fu0440u0435u0434u0435u043bu0435u043du0438u00a0 30 min. table 4. f.
