AB  - Hexachlorobenzene (HCB) is one of the 12 persistent organic pollutants (POPs) 
      listed in "Stockholm Convention". It is hydrophobic, toxic and persistent in the 
      environment. Due to extensive use in the past, HCB contamination is still a 
      serious environmental problem. Strong adsorption on solid particles makes the 
      remediation difficult. This paper presents an overview of the physiochemical 
      technologies for HCB remediation and disposal. The adsorption/desorption behavior 
      of HCB is firstly described because it comprises the fundamental for most 
      remediation technologies. Physiochemical technologies concerned mostly for HCB 
      remediation and disposal, i.e., chemical enhanced washing, electrokinetic 
      remediation, reductive dechlorination and thermal decomposition, are reviewed in 
      terms of fundamentals, state of the art and perspectives. The other 
      physiochemical technologies including chemical oxidation, radiation induced 
      catalytic dechlorination, ultrasonic assisted treatment and mechanochemical 
      dechlorination are also reviewed. The pilot and large scale tests on HCB 
      remediation or disposal are summarized in the end. This review aims to provide 
      useful information to researchers and practitioners regarding HCB remediation and 
      disposal.
