RADIOISOTOPE EXCITED X-RAY-FLUORESCENCE ANALYSIS OF ASHES FROM COAL-FIRED POWER-PLANTS IN TURKEY

Fifteen ash samples taken from filters and bottom products of boilers or chimneys of seven coal fired power plants in Turkey have been analy sed quantitatively for some minor elements using radioisotope energy d ispersive X-ray fluorescence (EDXRF). It is found that samples contain Cu, Zn, Rb, Sr, Zr, Mo, Cs, Sb, Ba, Pb, Y, La, Ce, Nd and Sm in diffe rent amounts. An ash sample taken from the electro-filter of the Ambar li, fuel oil fired-power plant was also analysed for comparison and fo und that it contained the smallest amount of potentially toxic element s.
