Oil agents produced from the degreasing treatment of synthetic fibers are typical pollutants in wastewater printing and dyeing, which may cause large-scale environmental pollution without proper treatment. Purifying oily dye (DTY) at a low cost is key problem present. In this study, biochar microspheres with oil removal ability were prepared derived waste bamboo chips using hydrothermal method. The structure microsphere was regulated by activation modification processes. Biochar characterized, their adsorption behaviors for explored. results show that efficiency improved significantly after secondary pyrolysis lauric acid grafting reaction. maximum COD quantity DTY 889 mg/g rate 86.06% 30 min. addition, kinetics showed chemisorption main manner. Considering raw materials, application could decrease avoid pollution.
