Few earlier studies investigated the removal of nitrates from the soils and groundwater using electrochemical methods, but attention on fluoride and other similar contaminants has received attention only recently. The behavior of these contaminants under electric field is similar to that of anionic metals; they electromigrate toward the anode, in opposite direction to the electro-osmotic flow. g. NaOH) is used to increase soil pH near the anode and enhance the removal. The effects of anode conditioning on electroosmosis should be considered as it will impact contaminant removal.
However, when they reach near the cathode, they get sorbed or precipitated due to increased pH resulting from OH− transport from the cathode. The actual removal from the soil is often negligible. Several studies reported similar results based on testing of field soils. The field soils possess complex mineralogy, organic content, and buffering capacity, which results in relatively low removal of metals. One of the most important considerations is the acid buffering capacity of the soil. If the soil possesses higher acid buffering capacity, soil pH does not reduce near the anode, but it increases near the cathode.
Alternatively, some researchers used zero-valent iron (ZVI) in the anode to increase soil pH and also to transform nitrate into nitrogen within the anode. Such strategy can also be implemented in an electrokinetic barrier system. It should also be pointed out here that nitrate is delivered into the soil purposely to enhance biostimulation in some studies, and the lessons learned from the studies dealing with the removal of nitrate can be useful for this purpose. The excess amount of nitrate should be avoided as it may be treated as contamination.
