Polychlorinated dibenzo-p-dioxins and dibenzofurans( PCDD /Fs) and dioxin-like polychlorinated biphenyls( dl-PCBs) were analyzed in the spent etching solutions and their recycling products tribasic copper chloride( TBCC). The contamination levels and distribution were evaluated after an elimination process was utilized. High resolution gas chromatograph /high resolution mass spectrometry( HRGC /HRMS) was employed for sample analysis. The results showed that the average concentrations of PCDD /Fs and dl-PCBs were 264 pg·mL-1and 139 pg·mL-1in the spent copper chloride solutions,while they were only 0. 09 pg·mL-1and 0. 50 pg·mL-1in the spent alkaline etching solutions. The concentrations in the TBCC samples were 106 pg·g-1( 2.79 pg WHOTEQ2005·g-1) and 27. 8 pg·g-1( 0. 69 pg WHO-TEQ2005·g-1) for PCDD/Fs and dl-PCBs,respectively. However, when an elimination process including adsorption and filtration was introduced into the production,the levels of toxic equivalence( TEQ) for PCDD /Fs and dl-PCBs were reduced to 0. 10—0. 25 pg WHO-TEQ2005·g-1and 0. 05—0. 72 pg WHO-TEQ2005·g-1,respectively,which are lower than the maximum levels established by European Commission. It suggested that the process could effectively reduce the amount of dioxin-like compounds during theproduction of TBCC with spent etching solutions.
