Sorption of lead on cementitious materials in presence of organics

Popis výsledku v původním jazyce

Commercial cementitious material, hydrated cement pastes of type CEM I and CEM III, and a synthetic cementitious phase CSH (calcium-silicate-hydrates) with a Ca/Si ratio equal to 1.0, 1.2, and 1.4 were used in the study of lead sorption. Kinetic and equilibrium experiments were performed under different conditions, namely liquid to solid phase ratio, under the presence of organic compounds (EDTA, phthalate), and also temperature. The duration of equilibrium experiments was determined based on kinetic experiments, 1 week for CSH and 3 weeks for HCP. Equilibrium experiments under different conditions (phase ratio, presence of organics) were evaluated using the distribution ratio Rd and the sorption isotherms. The effect of organic matter on sorption is described by the sorption reduction factor SRF.
