Ige. Ibeanu et al., NONDESTRUCTIVE XRF ANALYSIS OF NIGERIAN AND KENYAN CLAYS, Journal of radioanalytical and nuclear chemistry, 221(1-2), 1997, pp. 207-209
Nigerian and Kenyan clays were analysed using energy dispersive X-ray
fluorescence (EDXRF) technique and thirteen elements (Ca, Ti, Mn Fe, N
i, Cu, Zn, Br, Rb, Sr, Zr, Nb and Pb) were detected. The health implic
