METHODS AND SYSTEM FOR A MIXED LIQUID OXIDANT
Herein disclosed are compositions of mixed liquid oxidants and methods for their use in remediating soil and groundwater. The composition includes a mixture of permanganate and persulfate in liquid form. The method includes determining contaminants in soil and groundwater and applying the mixed liquid oxide to oxidize the contaminants.
1 . A composition of matter for remediating soil and/or groundwater contaminants, comprising:
0.02-50% permanganate compound;
0.02-50% persulfate compound; and
a balance of water.
2 . The composition of claim 1 , wherein the composition has a permanganate compound:persulfate compound ratio is about 100:1 to about 1:100.
3 . The composition of claim 1 , wherein the permanganate compound comprises at least one of sodium permanganate and potassium permanganate.
4 . The composition of claim 1 , wherein the persulfate compound comprises at least one of sodium persulfate, ammonium persulfate, potassium monosulfate, and potassium peroxymonosulfate.
5 . The composition of claim 1 , wherein the contaminant includes at least one of:
nitrobenzene, hexachloroethane, 1,1,1-tricholorethane, trichloroethylene, transition metals, heavy metals, and post-transition metals.
6 . A method for remediating soil and/or groundwater contaminants, the method comprising:
adding a mixed liquid oxidant to a soil.
7 . The method of claim 6 , further comprising:
determining at least one target contaminant present in the soil; and
selecting a composition of the mixed liquid oxidant based on the at least one target contaminant.
8 . The method of claim 6 , wherein the mixed liquid oxidant comprises:
0.02-50% permanganate compound;
0.02-50% persulfate compound; and
a balance of water.
9 . The method of claim 8 , wherein the permanganate compound comprises at least one of sodium permanganate and potassium permanganate.
10 . The method of claim 8 , wherein the persulfate compound comprises at least one of sodium persulfate, ammonium persulfate, potassium monosulfate, and potassium peroxymonosulfate.
11 . The method of claim 6 , where the mixed liquid oxidant has a permanganate compound:persulfate compound ratio is about 100:1 to about 1:100.
