Description of key information
Additional information
Green liquor is highly alkaline UVCB mixture of water soluble inorganic constituents, hydroxides, carbonates, sulfides, sulfites, sulfates as their water soluble alkaline metal salts. Water comprises 75% of the substance at minimum. Practically taken all of the inorganic constituents in Green liquor are industrial chemicals and also naturally occurring substances and part of the natural circulation of sulfur and carbon. Carbon is present as inorganic carbonate (CO32-). Sulfur is present in GL in several oxidation stages (S-2, SO3-, SO4-2, S2O3-) as soluble anionic alkaline metal salts. Reduced sulfide form predominates. Sulfate, sulfite, thiosulfate and sulfide are parts of the same abiotic sulfur circulation and these ionic constituents are very common in soil and aquatic environments. The transformation processes of these ions in the environment are mediated by a combination of abiotic and biological/microbiological processes. Sulfide ion is oxidized rapidly in surface water if free oxygen is available.
Volatilisation from water to air is low since the constituents are ionic. Gaseous hydrogen sulfide is generated from GL in contact with acids or if the prevailing pH is acidic. Gaseous hydrogen sulfide is a naturally occurring substance which can be typically found in low oxygen or anoxic regions of soil and sediment compartments, and as an evaporated gas in the atmospheric compartment.
The constituents of green liquor partition predominantly in to aquatic compartment. Adsorption to soil and sediments is ion specific. Anions are generally more mobile in soil than cations.
The constituents of green liquor are not bioaccumulative.
