Abstract
In
this work, the used biomass, for removing the mercuric species
from the liquid effluents of the chlor-alkali plants was the macro-algae
Sargassum sp. According to the results obtained, until this moment in time, it
was possible to remove more than 99% of the ionic mercury with the
advantage of not releasing me aqueous phase, that returns to the operation of
brine production, the electrolyte of the electrolytic cells. In addition, it was
verified that the biomass, once loaded with Mercury, can be reused in the biosorption
step, after suffering an elution process.
