Effects of two size fractions of platinum nanoparticles on properties of soil organic matter

Popis výsledku v původním jazyce

Nowadays, nanoparticles can be seen as a new type of pollutant which may have a negative effect on the environment compartments, including soil. Currently, there is only a limited number of studies investigating the effect of nanoparticles on soil properties. On the contrary, numerous articles reported the impacts on soil biota. Therefore, the aim of this study is to investigate how the 3 and 200 nm platinum nanoparticles affect selected properties of water and soil organic matter dried at various relative humidity (43, 75, and 95 %). These particles were selected due to their presence in the exhausting gases, where they are released from automotive catalysts. In this work, we determined the stability of water molecular bridges (proportional to structure rigidity), water holding capacity, evaporation enthalpy of water (the strength of water binding), the stability of aliphatic crystals (microbiological persistent fraction) in soil were studied using differential scanning calorimetry. It was discovered
