      copper-based preservative-treated wood after disposal.

AB  - Chromated copper arsenate (CCA)-treated wood was widely used until 2004 for 
      residential and industrial applications. Since 2004, CCA was replaced by 
      alternative copper preservatives such as alkaline copper quaternary (ACQ), copper 
      azole (CA) and micronized copper quaternary (MCQ), for residential applications 
      due to health concerns. Treated wood waste disposal is becoming an issue. 
      Previous studies identified a chemical process for decontaminating CCA-treated 
      wood waste based on sulfuric acid leaching. The potential application of this 
      process to wood treated with the copper-based preservatives (alkaline copper 
      quaternary (ACQ), copper azole (CA) and micronized copper quaternary (MCQ)) is 
      investigated here. Three consecutive leaching steps with 0.1 M sulfuric acid at 
      75 degrees C for 2 h were successful for all the types of treated wood and achieved more 
      than 98% copper solubilisation. The different acidic leachates produced were 
      successively treated by coagulation using ferric chloride and precipitation 
      (pH=7) using sodium hydroxide. Between 94 and 99% of copper in leachates could be 
      recovered by electrodeposition after 90 min using 2 A electrical current. Thus, 
      the process previously developed for CCA-treated wood waste decontamination could 
      be efficiently applied for CA-, ACQ- or MCQ-treated wood.
