A bioretention medium has considerable influence on the removal of pollutants, especially phosphorus pollutants. In this paper, the phosphorus adsorption properties of three bioretention media (sand, iron powder, and aluminum powder) are studied, and the effects of pH and ionic strength on the phosphorus adsorption are analyzed. Results show that the phosphorus adsorption isotherm can be well modeled by the Langmuir equation. The experimental results show the monolayer adsorption capacity of sand is the highest, while the iron powder the lowest. The pH of the solution has a considerable influence on the phosphorus adsorption of sand and iron powder, but has a minimal effect on aluminum powder.

The paper presents the results of studies on sorption and CO2 desorptions from coals from two Polish mines that differed in petrographic and structural properties. The tests were carried out on spherical and plane sheet samples. On the basis of the sorption tests, the effective diffusion coefficient was calculated on the plane sheet samples based on a proper model. Similar tests were performed on the spherical samples. Mathematical model results for plane sheet samples were compared with the most frequently chosen model for spherical samples. The kinetics of CO2 desorption from plane sheet samples were compared with the kinetics of sample shrinkage. In both samples, the shrinkage was about 0.35%. The size change kinetics and CO2 desorption kinetics significantly differed between the samples. In both samples, the determined shrinkage kinetics was clearly faster than CO2 kinetics.
