【 摘 要 】
The article reflects the results of research on the influence of roast temperature of water treatment waste obtained from drinking water generation (at the water treatment plant in Nizhnekamsk, Republic of Tatarstan) for sorption characteristics for native and used oil products - oils 5W40, 15W40 and И-20А. The methods of instrumental and computational means of research are presented. Differential thermal analysis and differential scanning calorimetry of water treatment waste were performed. The graphs of the influence of roast temperature on the aqueous extract pH value, maximum oil capacity and water absorption were constructed. It was found that at high temperatures, the decomposition of organic compounds with formation of carbon black occurs. It increases the maximum oil capacity in dynamic and static conditions in water and water absorption. It is determined that the best adsorption indicators are achieved for a sample of water treatment waste subjected to heat treatment at 600 C.
