INVESTIGATION OF TWO SLAG SAMPLES USING K0 NEUTRON ACTIVATION ANALYSIS THROUGH DIFFERENT STANDARDIZATION METHODS

Instrumental neutron activation analysis was applied to determine the concentration values of several major and trace elements in two Egyptian slag samples. Both samples are submitted one by a Steel factory and the other by an Aluminum factory in Egypt. The high accuracy of the elemental concentration values presented in this work is due to the Internal and External Comparator k0 method used. The two slag samples together with an international reference martial Soil-7 and two thin gold foils samples (One bare and the other covered with Cadmium) were irradiated in the core of the Second Egyptian Research Reactor ET-RR-2 , at about 13*10^13n / cm^2 sec. .The elemental concentration of 46Sc, 51Cr, 65Zn, 74As, 82Br, 85Sr, 86Zr, 110mAg, 122Sb, 134Cs, 131Ba, 140La, 141Ce, 147Nd, 153Sm, 152Eu, 153Gd, 166Ho, 169Yb, 175Hf, 182Ta, 198Au and 233Pa(232Th -series) are presented. Also, a comparison between the results of two methods is given as well as the elemental concentration comparison values between the two samples under investigation.
