Phnolic wastewater is difficult to handle in coking industry. Lignite Thermal Extraction Residue (LHER) is proposed as adsorbent. The effects of LHER, adsorption time and pH of mimic phenolic solutions on phenol removal are investigated. Results show that the phenol removal can reach 41.85% when 1.0 g LHER is added into the solution at pH 6 for 2 h
