The use of different cells for pH measurements for the determination of equilibrium constants of metal complexes is discussed in relation to the liquid junction potential connected with them. The effects of Hf and OH, on this quantity are also considered. The literature values for the conversion fac
Two computerized potentiometric methods have been used to determine the stability constants of Na+ , K', and NH: complexes with 18-crown-6 in methanol-water solutions (70% volume fraction of methanol) at 25.0 ? O.l"C, and at constant ionic strength I = 0.1 M, adjusted with tetrabutylammonium iodide
## Abstract Different biological materials such as edible oils, refined and unrefined cane and beet sugar and tea (black and green) leaves were assayed for the heavy metals cadmium, copper, lead and zinc. The results revealed significant differences in heavy metal contents within each class of the
