Abstract: Low molecular weight organic acids often influence the surface reactions(adsorption/precipitation) of minerals, which in turn affect the stability of elemental transport in environmental geochemical processes. The effect of malic acid on calcite-fluorine adsorption/precipitation reactions was investigated. The results show that(1) at the initial pH of 7.7 and lower F concentrations(≤5 mg·L-1), as the concentration of malic acid increases, its surface adsorption capacity becomes strong... More
