Study of Particle Size in Natural and Technological Water Suspensions Using Photon Cross Correlation Spectroscopy with Nanophox

摘要

Photon cross-correlation spectroscopy (PCCS) has become a novel light-scattering technique allowing for precise measurement of particle sizing and size distribution of suspensions colloids. The size and distribution of particles of suspensions including natural and technological water samples are studied by Photon Cross-Correlation Spectroscopy. The mean diameter, the size distribution range, the specific surface area of the particles in natural spring named Janchivlan are found to be 963±8 nm, 708 nm-1.4 μm and 6.27±0.01 m~(2)/cm~(3), respectively. On the other hand, these values corresponding to the particles in snow samples from the industrial zone of Ulaanbaatar city are determined to be 1.4 μm±70 nm, 947 nm-2.4 μm and 4.16±0.1 m~(2)/cm~(3). It can be assumed that high values in the mean diameter of natural spring and snow samples are related to composition of minerals and PM2.5 and PM10 particles.
