Relacje ilościowe między zawartością wybranych pierwiastków śladowych w glebie ekstrahowanych 0,03 M CH3COOH i 1 M HCL a zawartością ich form ogólnych w sałacie i szpinaku
No full textNumeorus analytical methods have been developed for determination of micronutrients, heavy metals and trace elements in soil. However, rapid and easy-to-perform methods are still needed for chemical composition analysis of soil that would be based on simultaneous extraction of multiple elements. Furthermore, it would be beneficial if element concentration in soil using these methods were correlated with its concentration in plants. The aim of the study was to determine the interdependency between soil concentration of: Al, B, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sr, Ti, V and Zn extracted using 0.03 M CH3COOH or 1 M HCl and its content in spinach leaves and lettuce heads. In reference to Al, B, Ba, Cd, Mn, Ni and Zn level in spinach as well as Al, B, Ba, Cd, Cr, Fe, Li and Ti accumulation in lettuce, higher values of correlation coefficients were calculated for soil and plant content of these elements after extraction with 0.03 M CH3COOH than 1 M HCl. In the case of: Cr, Cu, Fe, Li and Sr in spinach as well as Ni and Pb in lettuce, higher values of this parameter were found for 1 M HCl soil extraction when compared with the other tested method. No significant relation was found between Pb and Ti accumulation in spinach as well as Cu Mn, Sr or Zn content in lettuce and its level in soil irrespective of the extraction method (0.03 M CH3COOH or 1 M HCl).Opracowano wiele metod oznaczania zawartości mikroskładników, metali ciężkich oraz pierwiastków śladowych w glebie. Jednakże nadal istnieje potrzeba poszukiwania szybkich i łatwych do wykonania metod analizy składu chemicznego gleby, które byłyby oparte na wspólnej ekstrakcji wielu składników. Najlepiej, by zawartość składników oznaczona w glebach za pomocą tych metod była skorelowana z ich zawartością w roślinach. Celem badań było określenie zależności pomiędzy zawartością w glebie Al, B, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sr, Ti, V i Zn ekstrahowanych za pomocą 0,03 M CH3COOH (metoda uniwersalna) i 1 M HCl (test Rinkisa), a ich zawartością w liściach szpinaku i w główkach sałaty. W odniesieniu do zawartości: Al, B, Ba, Cd, Mn, Ni i Zn w szpinaku oraz Al, B, Ba, Cd, Cr, Fe, Li i Ti w sałacie wyniki badań wykazały wyższą wartość współczynników korelacji pomiędzy zawartością pierwiastków w glebie oznaczonych za pomocą 0,03 M CH3COOH niż w 1 M HCl a zawartością tych pierwiastków w roślinach. W porównaniu z ekstrakcją 0,03 M CH3COOH stwierdzono wyższą wartość współczynników korelacji, po oznaczeniu pierwiastków w glebie w 1 M HCl, z ich zawartością w roślinach w przypadku: Cr, Cu, Fe, Li i Sr w szpinaku oraz Ni i Pb w sałacie. Nie stwierdzono istotnego związku pomiędzy zawartością Pb i Ti w szpinaku oraz Cu Mn, Sr and Zn w sałacie, a zawartością tych pierwiastków w glebie, oznaczanych zarówno w ekstraktach 0,03 M CH3COOH jak i 1 M HCl
Wpływ nawożenia różnymi formami azotu na zawartość szesnastu pierwiastków w główkach kapusty czerwonej
No full textVarious forms of nitrogen fertilizer were applied in the cultivation of red cabbage (in the years 2003–2005), ‘Langendijker’ c.v.: control (unfertilized with nitrogen), Ca(NO3)2 , (NH4)2SO4 , NH4NO3 , CO(NH2)2 applied as solid fertilizers. This experiment aimed at determining the influence of various nitrogen forms on the content of Al, B, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sr, Ti, Zn, V in cabbage heads and the changes in the content of the available form of these elements for plants in soil after cabbage cultivation. The heads of plants fertilized with calcium nitrate and urea were characterized by the highest content of Al, Mn, Sr, Zn, Cd and Mo. Urea caused a significant increase in the content of Cu, Li and V, while ammonium nitrate resulted in an elevated level of Fe and Co accumulation in cabbage heads. Fertilization with (NH4)2SO4 led to a substantial decrease in the content of Al, Mo and V, and fertilization with NH4NO3 caused a decline in Sr concentrations in cabbage in comparison with other objects of the experiment. Each nitrogen fertilizer resulted in the decreased concentrations of Ti in cabbage heads. Applied nitrogen fertilizers significantly influenced the contents of readily soluble forms of B, Fe and Pb in soil after cabbage cultivation.Różne formy nawozów azotowych zastosowano w uprawie kapusty czerwonej (w latach 2003–2005), odmiany ‘Langendijker’: kontrola (nienawożona azotem), Ca(NO3)2, (NH4)2SO4, NH4NO3, CO(NH2)2 stosowane jako nawozy stałe. Celem badań było określenie wpływu różnych form azotu na zawartość Al, B, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sr, Ti, Zn, V w główkach kapusty oraz na zmiany zawartości fitodostępnych form tych pierwiastków w glebie po uprawie kapusty. Najwyższą zawartością Al, Mn, Sr, Zn, Cd i Mo charakteryzowały się główki roślin nawożonych, zarówno saletrą wapniową, jak i mocznikiem. Mocznik powodował także znaczny wzrost zawartości Cu, Li i V, a saletra amonowa podwyższenie poziomu akumulacji Fe i Co w główkach kapusty. Nawożenie (NH4)2SO4 powodowało istotne obniżenie zawartości Al, Mo i V, a nawożenie NH4NO3 obniżenie zawartości Sr w kapuście stosunku do pozostałych obiektów doświadczenia. Każdy z użytych nawozów azotowych powodował obniżenie zawartości Ti w główkach kapusty. Zastosowane nawozy azotowe w istotny sposób wpłynęły jedynie na zawartość łatwo rozpuszczalnych form B, Fe i Pb w glebie po uprawie kapusty

Oxygen-redox activity in non-Li-excess W-doped LiNiO2 cathode
No full textThe desire to increase the energy density of stoichiometric layered LiTMO2 (TM = 3d transition metal) cathode materials has promoted investigation into their properties at high states of charge. Although there is increasing evidence for pronounced oxygen participation in the charge compensation mechanism, questions remain whether this is true O-redox, as observed in Li-excess cathodes. Through a high-resolution O K-edge resonant inelastic X-ray spectroscopy (RIXS) study of the Mn-free Ni-rich layered oxide, LiNi0.98W0.02O2, we demonstrate that the same oxidized oxygen environment exists in both Li-excess and non-Li-excess systems. The observation of identical RIXS loss features in both classes of compounds is remarkable given the differences in their crystallographic structure and delithiation pathways. This lack of a specific structural motif reveals the importance of electron correlation in the charge compensation mechanism for these systems and indicates how a better description of charge compensation in layered oxides is required to understand anionic redox for energy storage
