Description:
The uptake behaviour of porous silica modified with N-propylsalicylaldimine (IE11) and Cd (II), Cr (III), Cu (II), Mn (II) and Pb (II) metal ions were studied. The Log kd values were found to be within the range 2.19 - 5.16 depending on pH and time of stirring. IE11 was used in the separation and preconcentration of Cd (II), Cr (III, VI), Cu (II), Mn (II, VII) and Pb (II) from some natural water samples. The data were compared with those obtained by the solvent extraction method (APDC/MIBK). The proposed methodology permits verification of improvements in the water quality of the Nile River, probably attributed to moderately high floods of the last few years. The method was found to be accurate and precise and not subject to random error.
