Leaching of the metals from PCBs was investigated with varying solid-to-liquid ratio in ammonium thiosulfate solution. As illustrated in Fig. 3, the increase in solid-to-liquid ratio from 0.1 g to 1 g/10 ml resulted in the decrease of metal extraction. At the maximum solid-to-liquid ratio in the present study (i.e., 1 g/10 ml), Au extraction was <5% due mainly to the lack of leaching reagent ...
