Abstract
In this study, different ratios of spent lubricating oil were used with fig wood (wood: spent oil, 1:1, 1:075, 1:0.5, 1:025), and it was carbonized at a temperature of 500 degrees Celsius (initial carbonization). The resulting carbon was chemically activated with sodium hydroxide in different proportions (non-activated carbon: sodium hydroxide 1:1, 1:0.5). Model 1 (1:1 wood: spent oil, 1:1 non-activated carbon: sodium hydroxide) was the best in terms of dye adsorption. Blue methylene, as well as in terms of iodine adsorption, in addition to the preference in physical properties (humidity, density, ash content).
