Extraction of available and labile fractions of mercury ...

27 100 mL of extractant favours mercury extraction. For the available fraction an 28 extraction of 30 minutes seems enough, as no further significant change was 29 observed in the quantity of mercury extracted thereafter. For the labile fraction 30 increase the extraction duration to at least 24 hours is recommended. 31 The data was fitted into kinetic models, and it was observed that the two ...
