Oxidation state of arsenic in coal ash leachate
Pond effluents from 12 coal ash disposal systems contained variable quantities of total dissolved arsenic. The more toxic trivalent oxidation state accounted for 3-40% of the dissolved arsenic and was correlated with total dissolved arsenic. Leaching studies indicated high variability among flyashes...

| Zusammenfassung: | Pond effluents from 12 coal ash disposal systems contained variable quantities of total dissolved arsenic. The more toxic trivalent oxidation state accounted for 3-40% of the dissolved arsenic and was correlated with total dissolved arsenic. Leaching studies indicated high variability among flyashes in the quantity and form of arsenic released initially from the solid phase. |
