The ash and residues of carbon materials, asphalt, water and dust are the main pollutants that result from the use of lubricating oils, which have serious effects on human health and the environment. The research aims to study the effect of various adsorption materials at different amount in purification of wastes lubricating oil, where the waste oil was treated with alumina, silica gel, Iraqi Attapulgite clay, where the results show that the last best in removing the ash materials from waste lubricating oil .The research focus in study the optimum conditions for adsorption by using Iraqi Attapulgite clay which include the amount of adsorbent temperature time of adsorption ,and speed of stirring during adsorption reaction. The results showed that the optimum conditions for adsorption 4g of adsorpant to 10 g of oil, at 60°C temperature for 60 min, with 600 rpm speed of stirring. The treated oil was viscosity, density, pour point, ash content, and total acid number were tested for treated oil and compared the results with the waste oil and fresh oil Viscosity(21.484),density(0.8740),pour point ( -17),flash point(192), acid number (0.448).
