Influence of Engineered Nanoparticles on Properties of Water in Soil Organic Matter

Popis výsledku v původním jazyce

Nowadays, engineered nanoparticles are largely used, making them a potential pollutant for the environment, including soil. Much research has been conducted on the potential adverse effects of nanoparticles on soil biota. However, the impact of nanoparticles on soil properties is not still fully understood. This work is focused on the influence of two types of 20-nm-sized titanium dioxide (TiO2) nanoparticles (rutile, anatase) on selected water properties in soil organic matter dried at various relative humidity (43, 70, and 95 %). The study builds on previous research on platinum nanoparticles, which revealed that these nanoparticles influenced three-dimensional water structure and, consequently, water properties. Using differential scanning calorimetry (DSC), we discovered that the titanium dioxide nanoparticles reduced stability of water molecular bridges (i.e., water clusters) under 70% relative air humidity. Also, a general decrease of water evaporation enthalpy, which represents water retention
