15 صفحه اولThe Effectiveness of Home Water Purification Systems on the Amount of Fluoride in Drinking Water
STATEMENT OF THE PROBLEM Water purification systems for domestic use have drawn significant attention over the past few years. This can be related to the improvement of public health and concern for water contamination. PURPOSE The aim of this study was to evaluate whether home water purification systems eliminate the essential materials such as fluoride besides filtrating the heavy ions and ...
متن کاملFormation of CdS Nanoparticles in Microemulsion Using Different Co-surfactant and Water to Surfactant Molar Ratio
Cadmium Sulphide (CdS) nanoparticles were prepared using microemulsion method using cadmium chloride as cadmium source and sodium sulphide as sulphur source. The obtained nanoparticles structures were characterized by X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM) whereas optical characterization was done by Ultra Violet-Visible absorption. XRD result shows that CdS nanopart...
متن کاملVariations in the amount of water ice on Ceres’ surface suggest a seasonal water cycle
The dwarf planet Ceres is known to host a considerable amount of water in its interior, and areas of water ice were detected by the Dawn spacecraft on its surface. Moreover, sporadic water and hydroxyl emissions have been observed from space telescopes. We report the detection of water ice in a mid-latitude crater and its unexpected variation with time. The Dawn spectrometer data show a change ...
متن کاملSpectrophotometric determination of trace amount of malachite green from water with novel magnetic silica nanoparticles
A nano-hybrid based on polystyrene derivatives and magnetite was introduced as a new sorbent for pretreatment and determine the trace amount of malachite green from aqueous solution by spectrophotometry after preconcentration by solid phase extraction (SPE). UV–Vis spectrophotometer was used for determination of MG concentration after desorption of the dye by hydrochloric acid solution in the s...
