However, in two soils the presence of forest litter counteracted the effects of waterlogging and diminished the quantities of released Sb. Soil waterlogging resulted, in most cases, in the increased release of Sb compared to oxic conditions, and this effect was enhanced by the addition of forest litter. In some soils, the application of forest litter prompted the release of Sb from soil solid phase, while in the others it acted contradictorily. ![]() The changes of Sb solubility caused by application of FL and prolonged waterlogging were, in various soils, highly divergent and in fact unpredictable based on the main soil properties. Water concentrations of Sb in some experimental treatments greatly exceeded the threshold values for good quality underground water and drinking water, and reached a maximum of 2.8 mg/L. Soils were incubated for 90 days either in oxic or waterlogged conditions, with and without the addition of 50 g/kg of beech forest litter (FL). Soils containing 12.8–163 mg/kg Sb were taken from the top layers of dumps in former mining sites in the Sudetes, South-West Poland.

Place, publisher, year, edition, pages2012. Besides that, useful correlations between 31P CSA parameters and structural data on this complex were also established. In this novel molecular structure, the central antimony atom S,S’-anisobidentately coordinates three structurally non-equivalent DTP groups and, therefore, the geometry of the chromophore can be approximated by a distorted octahedron. Using single-crystal X-ray diffraction technique, the molecular structure of a solvated form of crystalline O,O’-di-cyclo-hexyldithiophosphate antimony(III) complex has been resolved. 31P CP/MAS NMR and chemical shift anisotropy data indicate that the S–P–S bite angle of the chemisorbed DTP groups on the surface is larger than in the corresponding precipitated complexes and the coordination of the ligands differ. At high concentration of DTP, a surface precipitate of Sb(DTP)3 is formed. The results show that a low concentration of collector at the surface leads to a chemisorbed monolayer of DTP on the mineral surface. Corresponding individual complexes have also been synthesized and used for comparison with the surface adsorbed DTP species. 488-495 Article in journal (Refereed) Published Abstract įour different dialkyldithiophosphate (DTP) ions, (RO)2PSS– (R = C3H7, iso-C3H7, iso-C4H9, cyclo-C6H11) have been adsorbed on the surface of synthetically prepared stibnite, Sb2S3, and studied by means of 31P CP/MAS NMR. 2012 (English) In: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol.
