Simultaneous Determination of Zinc, Cadmium, Lead and Copper in Water by Potentiometric Stripping Analysis
Analysis of zinc (In) cadmium (Cd), lead (Pb) and copper (Cu) in drinking and irrigation waters by potentiometric stripping analysis (PSA) is described. The pH and EC of waters were also determined. The results for zinc and copper were compared with those obtained by atomic absorption spectrophotometry (AAS) which indicated a significantly (P<0.01) strong correlation (r = 0.994 and 0.984 for In...
متن کاملPhytoextraction of cadmium, copper, zinc and mercury by selected plants
During the years 2006 and 2007 the phytoextraction ability of maize (Zea mays), willow-tree (Salix smithiana) and poplar (Populus nigra × P. maximowiczii) to accumulate cadmium, copper, mercury and zinc was investigated. Small scale field experiment was carried out on soil contaminated with chemicals from the waste incineration plant in Hradec Kralové (Czech republic). Screening of this allotme...
متن کاملA Convenient Method for Potentiometric Titration of Chloride Ions
A convenient reference cell and method of potentiometric determination of chloride ions with silver nitrate is described. The method is accurate to about +/- 0.02 ml. 10(-4)M silver nitrate.
متن کاملPrecise chelatometric titrations of zinc, cadmium, and lead with molecular spectroscopy.
Spectral data during a chelatometric titration were utilized for determining an equivalence point of the titration. Three-dimensional titration data were analyzed by fitting to a theoretical equation that was derived from equilibrium equations among a metal ion, an indicator and EDTA. The equation with optimized parameters successfully explained the three-dimensional titration data. This method...
متن کاملSimultaneous determination of lead, cadmium, copper and zinc in Infant formula by anodic stripping voltammetry
Determination of trace elements in food is of great importance, as some of them have nutritional significance, whilst others are toxic. Long-term exposure to low levels of toxic metals could be important, especially in relation to children. Differential Pulse Anodic Stripping Voltammetry (DPASV) is applied to simultaneous determination of lead, cadmium, copper and zinc in dry ash infant formula...
