Among the three main plasma techniques, particular attention is paid to the...

Marie Skłodowska-Curie ? on the shoulders of giants, thinking outside the box*

Marie Skłodowska-Curie ? on the shoulders of giants, thinking outside the box * PETELENZ B. Please cite as: CHEMIK 2013, 67, 8, 675?682 Abstract: The paper points out some circumstances and some people that ? directly or indirectly ? influenced the scientific development of Marie Skłodowska-Curie, the only winner of the Nobel Prizes both for Physics and for Chemistry. It also focuses on some aspects of her intellectual approach which revolutionized the science in the late 19th and early 20th century. Keywords: Marie Skłodowska-Curie, polonium, radium, radioactivity, structure...

Evaluation of performance properties of surfactants applied in compounds intended for the removal of oil-based substances

Evaluation of performance properties of surfactants applied in compounds intended for the removal of oil-based substances Zuzanna ŚLOSORZ, Katarzyna RADWAN, Joanna RAKOWSKA ? Centrum Naukowo-Badawcze Ochrony Przeciwpożarowej im. J. Tuliszkowskiego, Państwowy Instytut Badawczy (CNBOP-PIB), Józefów Please cite as: CHEMIK 2013, 67, 8, 725?732 Abstract: The article presents the results of the tests of agents comprising surface active compounds (SAC) that serve to remove oil-based contaminants from the surface of solids. Nonionic and anionic surface active compounds have been selected for tests. The results obtained confirm...

Water adsorption in the zeolite bed ? study on thermal effects

Water adsorption in the zeolite bed ? study on thermal effects Jan RAKOCZY, Krzysztof KUPIEC, Monika GWADERA ? Faculty of Chemical Engineering, Tadeusz Kościuszko Cracow University of Technology, Poland Please cite as: CHEMIK 2013, 67, 8, 711?718 This paper presents the results of studies on adsorptive dehydration of fuel ethanol on zeolites. During the process, a huge amount of heat is generated which causes a significant increase of the bed temperature. The changes of the temperature of the adsorbent bed were determined in time...

Selective catalytic oxidation (SCO) of ammonia into nitrogen and water vapour over hydrotalcite originated mixed metal oxides ? a short review

Selective catalytic oxidation (SCO) of ammonia into nitrogen and water vapour over hydrotalcite originated mixed metal oxides ? a short review Magdalena JABŁOŃSKA, Lucjan CHMIELARZ, Agnieszka WĘGRZYN ? Faculty of Chemistry, Jagiellonian University in Krakow, Poland Please cite as: CHEMIK 2013, 67, 8, 701?710 Selective catalytic oxidation of ammonia into nitrogen and water vapour is currently regarded as one of the most promising technologies for abatement of ammonia emissions from waste gases. This paper gives an overview of SCO technology, including the catalyst development and...

Sorption of heavy metal complexes with MGDA on the macroporous anion exchanger Purolite A830

Sorption of heavy metal complexes with MGDA on the macroporous anion exchanger Purolite A830 Justyna JACHUŁA, Zbigniew HUBICKI ? Department of Inorganic Chemistry, Maria Curie-Skłodowska University, Lublin, Poland Please cite as: CHEMIK 2013, 67, 8, 693?700 Abstract: The aim of the paper is to present the research on sorption of heavy metals Cu(II), Zn(II), Cd(II) and Pb(II) with methylglycinediacetic acid (MGDA) on the weakly, basic, - acrylic anion exchanger Purolite A830. Sorption depends on such factors as: chase contact time, pH, concentration, temperature and...
