Wydział Górnictwa i GeoinżynieriiItem type:Article, Access status: Open Access , Chemical and biological analysis of chromium waste(Wydawnictwa AGH, 2009) Hołda, Anna; Kisielowska, Ewa; Niedoba, TomaszThe paper presents chemical and microbiological analysis (were from qualitative and quantitative point of view) of the collected samples of wastes. The procedure of chemical analysis is based on a quantitative extraction of Cr(VI) from the solid samples and its determination in the extract by the method of flow coulometry by means of apparatus EcaFlow 150GLP, applying calibration by method of model curve. The determination of chromium by flow coulometry is based on utilization of inner electrode coulometric titration. Microbiological analysis shows that the concentration of chromium(VI) above 2000 mg/l is toxic for psychro- and mesophilous bacteria, stopping the growth of their colonies, but fungi from sort Rhizopus sp. and Penicillium sp. are tolerant for high concentrations of chromium(VI).Item type:Article, Access status: Open Access , Influence of heavy metals on soil microflora(Wydawnictwa AGH, 2010) Hołda, Anna; Kisielowska, Ewa; Niedoba, TomaszThe purpose of the research presented in the paper was to conduct the heavy metals contents in area of tannery plant and to determine their influence on soil microflora. The soil samples were collected to this purpose from the area, which was surrounded by the industrial buildings from one side (tannery, galvanic plant and chemistry plant) and by river Wilga and two small ponds from three remaining ones, which supposedly collect the sewers from these plants. The collected samples were then chemically and microbiologically analyzes. The contents of metals as Cu, Cd, Pb and Zn were determined by culometric method. On the basis of conducted analyzes it was proved that soil on the researched area was polluted by heavy metals. Mainly chromium contents in every sample was high what means that the tannery wastes occurs in the area of collecting samples. The investigation proved the influence of heavy metals on soil microflora. Various sorts of microorganisms have various tolerance on high metals concentration. The most resistant were ferruginous, nitrificative and denitrificative bacteria, the less resistant were meso- and psychrophilic bacteria and fungi.Item type:Thesis, Access status: Restricted , Metody unieszkodliwiania zagrożeń chemicznych w pożarnictwie(Data obrony: 2014-02-12) Garbaciak, Jakub

Furthermore, the influence of microorganisms on sludge properties was investigated. By application of ASA method, the following metals contents were determined: magnesium, calcium, lead, cadmium, copper, nickel, mercury and zinc. Furthermore, the biogenous factors were determined, as amonium nitrogen, overall nitrogen and phosphor. The influence of microorganisms on sludge was also investigated. To this purpose the results given from daily and 3-weekly sludge were compared. The conducted chemical analysis proved that after 3 weeks of storage, concentrations of heavy metals were lowered what may be caused by biochemical activity of microorganisms, which growing amount prove this observation.Item type:Thesis, Access status: Restricted , Rekultywacja kopalń odkrywkowych na przykładzie Zakrzówka(Data obrony: 2015-01-29) Jędrzejczak, Adrian

The paper presents the problems of possible applications of microorganisms in processes leading to removal of heavy metals from various environments, including coals. The processes occurring with participation of microorganisms as biosorption, bioaccumulation, biotransformation, bioprecipitation, biocrystallization and bioleaching, which can be practically applied in removal of heavy metals from coals connected with their recovery were described in the paper. Furthermore, the examples of interesting works from this area of scientific interest, conducted in various research units in Poland were presented.Item type:Book, Access status: Restricted , Technologia wody i ścieków : ćwiczenia laboratoryjne.

Badanie procesu bioługowania przeprowadzono z zastosowaniem grzybów z gatunku Aspergillus niger, które dominują w środowisku autochtonicznym. Metabolizm tych grzybów, związany z produkcją znacznych ilości kwasów organicznych, pozwala na użycie ich w procesach biohydrometalurgii srebra. Po wyizolowaniu czystej kultury biomasy Aspergillus niger i jej pomnożeniu rozpoczęto eksperyment. Zważone próbki odpadów zostały pokryte wybraną pożywką a następnie zaszczepione biomasą mikrogrzybni, która pełniła rolę odczynnika bioługującego. Po trzydziestu dniach inkubacji produkt końcowy został zanalizowany chemicznie, pokazując efekty przeprowadzonego procesu bioługowania (12-41,5%).
