Chemical & Mineralogical Properties of Fly Ash
(Malaysian Nuclear Society, 2007)
Fly ash is the finely divided mineral residue resulting from the combustion of coal in electric generating plants. Fly ash consists of inorganic, incombustible matter present in the coal that has been fused during combustion ...
Comparative Study of Clinker’s Transformation at Different Temperature Zone During Cement Production
(Science Publications, 2007)
Chemical composition analysis using x-ray fluorescence is one of the important quality
analysis for examining of cement and widely used in cement industries for a long time as a tool to estimate phase composition. X-ray ...
Kinetics of adsorption of Cu(II) and Cd(II) from aqueous solution on rice husk and modified rice husk
(University of Vigo, 2007-02)
The present study is aimed to investigate the adsorption behavior of Cu(II) and Cd(II) ions onto rice husk and modified rice husk. The adsorption of the heavy metal ions over both the adsorbents was found to follow Langmuir ...
Treatment of methylene blue-containing wastewater using microorganisms supported on granular activated carbon under packed column operation
(Springer-Verlag, 2007-05)
We studied the feasibility of using biological granular activated carbon-packed column in treating methylene blue-containing wastewater. The granular activated carbon with immobilized microbes was packed into a column and ...
Changes in biologically-active ultraviolet radiation reaching the Earth's surface
(The Royal Society of Chemistry & Owner Societies, 2007)
The Montreal Protocol is working. Concentrations of major ozone-depleting substances in the atmosphere are now decreasing, and the decline in total column amounts seen in the 1980s and 1990s at mid-latitudes has not ...
Removal of chromium (VI) from aqueous solution using treated oil palm fibre
(Elsevier B.V, 2007-07-17)
This study proposed an oil palm by-product as a low-cost adsorbent for the removal of hexavalent chromium [Cr (VI)] from aqueous solution. Adsorption of Cr (VI) by sulphuric acid and heat-treated oil palm fibre was conducted ...
Climate augmentation of erythemal UV-B radiation dose damage in the tropics and global change
(Indian Academy of Sciences, 2007-12-10)
Skin cancer (UV carcinogenesis) causing erythemal solar ultraviolet-B (UV-B) radiation dosages received at tropical latitudes are about five times higher compared to mid-latitudes. The tropical environment also experiences ...
Comparative Characterization of Clinker’s Microstructure at Different Temperature Zone during Cement Production
(Science Publications, 2007)
Temperature is an important parameter for transformation of minerals in clinker during
cement productions. It influences the formation of alite from belite during calcinations and clinkering processes. The result of ...
