Iron leaching from fly ash has been investigated under simulated ammonia-based wet flue gas desulfurization conditions to determine the effects of the reaction temperature, initial pH value, liquid/solid ratio, and vibration frequency. The experimental results indicated that the ferric ion concentration in solution increased with the increase of the temperature and vibration frequency and the decrease of the pH value and liquid/solid ratio. The kinetics of iron leaching can be expressed as diffusion combined with a surface chemical reaction model. The reaction path can be described by the equation: 1 - (1 - a)1/3 = kt. The apparent activation energy was estimated to be about 20.01 kJ/mol. Such a value of the activation energy indicates that the leaching of iron under experimental conditions is controlled by both chemical reaction and diffusion. | ||
