This work presents the results of determination of lead in the soils of six allotment gardens located in different parts of the city (in the centre and on the outskirts). Lead was determined spectrophotometrically in the form of pink lead(II) ditizonate.
Cadmium was determined in the soil of six allotment gardens of Lodz, situated in areas with different traffic patters (the centre of the city and its suburbs). It was determined in the form of cadmium (II) dithizonate by the extraction-spectrophotometric method.
The content of copper in the soil of two allotment gardens in Lodz and a forest area near Lodz were determined. Copper was determined by an adapted extraction spectrophotometric method in the form of a complex with sodium(I) diethyldithiocarbamate. The influence of the extraction solvent, a masking agent and interfering elements (Fe(III) and Cr(IH)) on… (More)
Our work presents the results of the determination of bioavailable and total chromium (III) and chromium (VI) in the soil of an allotment garden situated in the center of £ódŸ. Chromium was determined by the spectrophotometric method in the form of a purple-red Cr (VI) complex with 1,5-diphenylcarbazide in the acid medium, following the establishment of the… (More)
The ability of oligosaccharides to disperse iron hydroxide (III) was investigated. It was found that products of electrochemical oxidation of oligosaccharides (aldonic acid) exhibit higher dispergation activity them the corresponding oligosaccharides.
