Journal ArticleDOI
Desilication of ZSM-5 and ZSM-12 zeolites : impact on textural, acidic and catalytic properties
TL;DR: In this paper, two zeolites of different topology were subjected to desilication in the NaOH solutions of increasing concentrations, and it was shown that desilization led to the formation of mesopores.
Journal ArticleDOI
Effect of selenium on macro- and microelement distribution and physiological parameters of rape and wheat seedlings exposed to cadmium stress
Maria Zembala,Maria Zembala,Maria Filek,Maria Filek,Stanisław Walas,Halina Mrowiec,Andrzej Kornaś,Zbigniew Miszalski,Zbigniew Miszalski,Helinä Hartikainen +9 more
TL;DR: The Cd stress and the protective role of Se were most evident in rape, and the Finnish wheat genotype was less tolerant to Cd than the Polish one, indicating an activity of detoxifying SH groups and SOD isoenzymes.
Journal ArticleDOI
Current approaches to calibration of LA-ICP-MS analysis
TL;DR: In this article, a review of recent calibration approaches and related standards preparation techniques for the analysis of various solid materials by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is presented.
Journal ArticleDOI
Preparation of a new Cd(II)-imprinted polymer and its application to determination of cadmium(II) via flow-injection-flame atomic absorption spectrometry.
Marta Gawin,Jadwiga Konefał,Bartosz Trzewik,Stanisław Walas,Anna Tobiasz,Halina Mrowiec,Ewa Witek +6 more
TL;DR: The new Cd(II)-imprinted polymer exhibited improved selectivity towards cadmium( II) against other heavy metal ions, especially Cu(II) and Pb(II), as well as light metal ions.
Journal ArticleDOI
Membrane permeability and micro- and macroelement accumulation in spring wheat cultivars during the short-term effect of salinity- and PEG-induced water stress
Maria Filek,Stanisław Walas,Halina Mrowiec,Elżbieta Rudolphy-Skórska,Apolonia Sieprawska,Jolanta Biesaga-Kościelniak +5 more
TL;DR: In this article, the authors compared the responses of ten spring wheat cultivars to water stress and found that the plants were more significantly influenced by water stress stimulated by PEG than by NaCl treatment, as compared to the plants cultivated in the control media.
