AB  - An in situ electrokinetic remediation technique was designed by combining the 
      uniform electrokinetic technology with a new-type of bamboo charcoal as 
      adsorbent. A bench-scale experiment was conducted to investigate the application 
      of this technique for simultaneous removal of 2,4-dichlorophenol (2,4-DCP) and Cd 
      from a sandy loam at different periodic polarity-reversals. The contaminated soil 
      was artificially spiked with 100 mg/kg 2,4-DCP and 500 mg/kg Cd. Two modes of 
      polarity-reversal intervals of 12 and 24 h were included. After 10.5 d of 
      operation, about 75.97% of Cd and 54.92% of 2,4-DCP were removed from soil at 
      intervals of 24 h, whilst only 40.13% of Cd and 24.98% of 2,4-DCP were removed at 
      intervals of 12 h. Soil water contents under two operation modes both 
      significantly decreased, but evenly distributed spatially. Soil pH values under 
      two operation modes were all maintained in the range from 7.2 to 7.4, close to 
      the initial value. The electricity consumption per day was 12.24 and 11.61 
      kWh/m(3)/d, respectively at polarity-reversal intervals of 12 and 24 h. In 
      conclusion, at polarity-reversal interval of 24 h, electroremediation combined 
      with activated bamboo charcoal was effective in simultaneous removal of 2,4-DCP 
      and Cd from soil. Our results indicate a promising potential in in situ 
      electroremediation of soils co-contaminated with organics and heavy metals.
