| In this article, the process of absorption of various hydrogels and their optimal concentration in distilled, stream, underground (drainage) water at pH 5, 7 and 9 were determined. AQUASORB from France, STOCKOSORB from Germany, Mujiza hydrogel from Uzbekistan were used in the experiment. According to the results, 12.5 g AQUASORB, 15 g STOCKOSORB, and 60 g Mujiza were used in 1 L distilled water with a medium pH of 5 and a gel of 100% volume was formed. When the pH of the distilled water was 7, 15 g AQUASORB, 20 g STOCKOSORB, and 50 g Mujiza were used. Distilled water was alkaline, when pH was 9 and 10 g AQUASORB, 7.5 g STOCKOSORB, and 40 g Mujiza were used. It was determined that the hydrogels' sorption amount was in different concentrations even when the water of the stream and well (drainage) were pH 5, 7 and 9, and a recommendation was given for its use. | ||
