Abstract：Chemical leaching has been widely used for emergency treatment of pollution sites due to high leac-hing effect,short time and convenient disposal.However,the effects of the hydrochemistry and sediment char-acteristics are unknown.However,the effect of ion strength negligible.Large particle size,sandy soil,fulvic acid enriched soil and suitable solid-liquid ratio(1:15)conducive to F-leaching.The degree of influence on response surface of F-leaching was pH,solid-liquid ratio,texture,particle size,ion strength,HCO-3.The results provide technical support and scientific guidance for ensuring the leaching effect of chemical leaching for emergency treatment of high F-sediments and implementing rapid emergency treatment of polluted sites.
