Determination of Elemental Composition of River Water and Slime by PIXE Method

The application of PIXE method was developed for determination of concentration of different elements in river water and bottom slime. The internal standard technique was applied for quantitative evaluation of contents of different elements. In case of river water yttrium standard was used in form of yttrium nitrate solution. The measurements for bottom slime was performed with external beam using standards with predetermined concentration of different elements. The concentration of following elements: S, Cl, K , Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Se, Br, Rb, Sr, Zr, Hg, Pb was determined with the described procedure. The estimated concentration of elements ranged from about 0.05 to about 200 ppm for water samples and from about 1.5 to about 30000 ppm in bottom slime samples.
