Sulphates, nitrates, and chlorides in particle fractions of different size.
This paper describes a pilot study of chloride, nitrate, and sulphate content in thoracic and high-risk respirable fractions of airborne particles. Samples were collected at one measuring site in Zagreb in autumn 1998 and spring 1999. The results showed that almost total chloride, nitrate, and sulphate content was present in the respirable particle fraction. The average mass contribution of the...
متن کاملA method for generating uniform size-segregated pyrite particle fractions
BACKGROUND Standardized sample preparation techniques allow comparison of pyrite dissolution experiments under diverse conditions. Our objective was to assess dry and wet sieving preparation methodologies, and to develop a reproducible technique that yields uniformly size-distributed material within a limited size range of interest. RESULTS Here, we describe a wet sieving preparation method t...
متن کاملPARTICLE SIZE CHARACTERIZATION OF NANOPARTICLES – A PRACTICALAPPROACH
Abstract: Most properties of nanoparticles are size-dependent. In fact, the novel properties of nanoaprticles do not prevail until the size has been reduced to the nanometer scale. The particle size and size distribution of alumina nanoparticle, as a critical properties, have been determined by transmission electron microscopy (TEM), photon correlation spectroscopy (PCS), surface area analysis ...
متن کاملCharacterization of polychlorinated dibenzo-p-dioxins and dibenzofurans in different particle size fractions of marine sediments.
The distribution of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) was examined according to particle size in marine sediments, with a particular focus on fine particulates. Samples from different coastal sites were fractionated into five size groups (<2, 2-5, 5-10, 10-20, and 20-63 microm diameter) by gravitational split-flow thin fractionation. Despite the different size profil...
متن کاملInactivation of Fecal coliforms during solar and photocatalytic disinfection by zinc oxide (ZnO) nanoparticles in compound parabolic concentrators (CPCs)
Water samples of 0, 50, and 100 nephelometric turbidity units (NTU) spiked with fecal coliforms (107 CFU/ml) were exposed to natural sunshine in 1l quartz glass tubes fitted with rectors’ compound parabolic concentrators CPCS at two forms CPC1 (whit nanoparticle zinc oxide) and CPC2(without nanoparticle zinc oxide). The samples were characterized using the X-ray...
