| Abstract |
It was studied that the trace amounts of thorium in Na₂WO₄ solution was removed through the adsorption of thorium by ferric hydroxide. The adsorption of thorium in Na₂WO₄ solution took place above pH 10. When the concentration of Na₂WO₄ was higher than 0.050M, the adsorption of thorium was increased with increasing pH. The increase of Na₂WO₄ concentration caused the adsorption of thorium to decrease. The increase of temperature caused the adsorption of thorium to decrease. The adsorption of thorium by ferric hydroxide followed Freundlich isotherm. |
