In order to investigate copper, arsenic, lead and zinc contamination in topsoil of the Erdenet copper mining area Mongolia, soil samples collected from surrounding were examined for trace element concentrations, geochemical fractions, phase distributions. Fifteen locations (residential area; mine industrial control tailings dam) sampled during all four seasons. Of 19 elements determined, highest concentrations Cu (1443–4866 mg kg −1 ), As (26–52 Mo (24–49 ) soils exceeded corresponding...
A new kinetic analytical method for evaluating the grinding rate constant via uniformity of particle size distribution during a process was investigated. The experiments were carried out at various slurry concentrations. stirring ball mill used. relationship between and K evaluated. value decreased with increase in ground sample, varied experimental conditions. K, which is related to raw increased low
Natural zeolite beads were prepared by encapsulating mesoporous into alginate via egg box method and its adsorption properties of Pb(II) ions investigated in aqueous solution. Crystallinity size reduction natural enhanced mechanic modification the ball milling process. FTIR SEM-EDS analyses confirmed that mechanically modified particles incorporated hydrogel. The highest amount was 87.47 mg/g after 20 h result process has occurred on surface beads. Adsorption kinetic data fitted with...
Most microcapsule preparation methods produce a population of microcapsules in bulk solution. To control the or obtain an optimal condition, mechanism should be investigated. The is estimated via structure reformation during process because diameter and wall thickness are drastically altered Considering applications, some important properties, such as mechanical properties release rate encapsulated product, depend on structure. In this study, polystyrene containing saline water droplets were...
We have developed a novel filtration technique by adding dispersants instead of flocculants which are commonly used for solid liquid separation. Slurries were prepared adjusting the pH values in order to control dispersion and flocculation degree particles. The slurries concentrated gravitational settling condensation or pressure condensation. In flocculated slurry, cake was formed on filter media therefore cannot be continued unless excreted mechanical hand-scraping device. addition...
Effect of N719-dye adsorption into TiO films prepared via incorporating small (~15 nm) and large (~300 nanoparticles at several ratios were investigated to improve the photovoltaic efficiency dye-sensitized solar cell. The is significantly improved after incorporation nanoparticles. From experimental result, composition with 70% small: 30% found as an optimum mixing ratio for best performance (5.57%) a This high attributed effect following factors. Besides increase in dye molecules...
Abstract For the microcapsules preparation process, mechanism is estimated by structure reformation during process since diameter and wall thickness drastically changed. Microstructures are recently studied machine learning techniques. The Hough transformation algorithm used other researchers for of but it difficult to determine using only a change microcapsules. Therefore, one additional way establish analysis formation microcapsule structure. In this study, was image segmentation, simple...
In this study, the structural characteristic and adsorption properties of heavy metals on Mongolian natural minerals were investigated. The samples confirmed as Heulandite group Clinoptilolite type zeolite clay sample that contains albite quartz by X-ray diffraction analysis. According to BET surface analysis, zeolites have mesoporous pore. results study showed ability is high effective for lead ion in acidic aqueous solution order metal selectivity was Pb2+>>Zn2+>Cd2+. performance...
An experimental investigation has been conducted on grinding of copper powders using different ball-milling machines. A various parameters including rotation speed and time ball sizes are used to change the particle morphology powders. The effects mill operation condition Cu in dry-type milling process three types mill: traditional (TBM), stirred (SBM), planetary (PBM). new evaluation method, which can provide relatively accurate results, is analyze compare performance millings. results...
