Adsorption of organic compounds onto activated carbon in water treatment process
Kopecká, Ivana
The dissertation thesis focuses on the application of activated carbon for the removal of low molecular weight algal organic matter (AOM) produced by phytoplankton during drinking water treatment, as well as on the effect of AOM on adsorption of anthropogenic micropollutants contained in raw water. The results of this study have been published in international peer-reviewed journals in 4 papers and in 2 conference contributions. The efficiency of AOM removal was studied in laboratory equilibrium and kinetic experiments using different types of granular activated carbon and cellular peptides with molecular weight < 10 kDa produced by cyanobacterium Microcystis aeruginosa. It has been previously confirmed that these peptides are removed with difficulty during the conventional water treatment based on coagulation/flocculation processes and therefore, other methods need to be applied for their restriction. The effect of solution properties on peptide adsorption was assessed by the tests at different pH values and at variable ionic strengths. The negative impact of peptides on the adsorption of organic micropollutants present in raw water was simulated using competitive adsorption experiments with herbicides alachlor and...

Problémy konvergence při integrálním modelování 3D elektrostatických polí se singularitami
Hamar, R. ; Doležel, Ivo
Numerous electrostatic fields are characterized by the presence of singularities (for example, at the corners or along the edges of electrically conductive charged bodies). Solutions to the tasks involving such elements by classic low-order differential methods often lead to inaccurate results. One of the prospective methods seems to be the integral approach starting from finding the distribution of the charge using the system of the first-kind Fredholm equations. The paper shows an application of this approach to two electrically conductive cubes in a general position in space. Discretization of their surfaces is performed in several different ways and the results are compared with respect to their convergence.
