Abstract

Anions from blast furnace slag (F~, Cl", Br", NO3, NO2 and SO|") significantly influence the environment, human health, and the stability of structures. Particular attention is paid to reactions between the slag and the solution of the anions in question (of defined concentration) in the duration of 1 hour to 30 days.
The anions were determined by means of the ion chromatographic analysis modified for different proportions of anions in eluents.
The results of elution within reactions between slag and media point to the inertness of the system. The fluoride saturation factors of the system were experimentally determined and calculated with the help of distribution coefficients.
