Abstract:
A BCR-sequential extraction procedure for the determination of extractable heavy metals was applied to sediments of various rivers and lakes. There are many rivers basins in Turkey. Sakarya River Basin is one of the most important basins, which consists of three parts: Upper, Middle and Lower Sakarya River Basins. In this study, the Lower Sakarya River was selected as the study area for sediments. The samples were collected monthly from 10 pre-determined stations through the river for 10 months time and analysed for the distribution of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn elements. The determination of extractable heavy metals in sediments was carried out by using Flame Atomic Absorption Spectrometer. The validation of the results was performed by the analysis of a BCR 701 standard reference material.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
