چکیده
|
In this study,fly ash was obtained from matla power station and the physicochemical properties investigated. the fly ash was characterized by x-ray fluorescence,x-ray diffraction,scanning electron microscopy,and inductively coupled plasma mass spectrometry. surface area,particle size,ash and carbon contents,ph,and point of zero charge were also measured. the results showed that the fly ash is alkaline and consists mainly of mullite (al 6si 2o 13) and quartz (sio 2). highly toxic metals as,sb,cd,cr,and pb as well as metals that are essential to health in trace amounts were also present. the storage and disposal of coal fly ash can thus lead to the release of leached metals into soils,surface and ground waters,find way into the ecological systems and then cause harmful effect to man and its environments. © 2012 hindawi publishing corporation.
