Decontamination efficiency of citric acid and dissolution reaction of Fe3+ ion on TRIGA soil artificially contaminated with Co2+ ion
AbstractAbstract
[en] A series of batch scale experiments was conducted to investigated the decontamination efficiency of citric acid on TRIGA soil artificially contaminated with Co2+ ion in the concentration range from 0.005M to 0.1M, under the pH solution of 3.0 to 10.0. The fraction diagram was calculated by equilibrium constant of Co2+ ion, Fe3+ ion and citric acid. The desorption rate of Co2+ ion was increased at low pH, but it was decreased at base zone. The dissolution rate of Fe3+ ion was same result against the various pH. The desorption reaction of Co2+ ion and the dissolution reaction of Fe3+ ion by citric acid both in acid solution and in base solution were suggested
