Item Separation of Bi, Ca, Cd, Cr, Co, Cu, Fe, Mn, Mo, Ni, Pb, Se, Sn, Ti, V and Zn in soil samples using thenoyltri:fluoroacetone as the most selective single ligand by the appropriate use of solvent extraction under the optim~m pH conditions(University of Fort Hare, 2003-01) Mamela, Mojalefa DanielIn this investigation, three soil samples collected from non-arid land were qualitatively analysed using both the electron microscopy and AAS methods and elements such as Bi, Ca, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Se, Sn Ti, V and Zn were positively identified in each of them. However, the electron microscopy method also revealed the presence of Na, K and Mg in these samples. Due to the logistical problems our scope of analysis was restricted to the first sixteen elements only.
