Abstract

For wastewater treatment, native and thermally modified samples of leaf chestnut litter (LCL) were used as sorption material. Studies were carried out to determine the static oil capacity of the sorption material (SM) in relation to the diesel fuel (DF) and water adsorption depending on the particle size. It was established that the oil capacity of chestnut litter depends on the particle size of the biosorption material, the conditions of its heat treatment, and the duration of contact of the SM with the sorbate. It was found that the maximum sorption capacity by DF for LCL250 is 7.17 g/g. It was determined that the purification efficiency of over 95% is achieved with a dosage of LCL250 over 1.0 g/dm3 and a diesel fuel concentration of 210 mg/dm3.
