Plants that occur on heavy metal contaminated soils are called metallophytes. Some of them, known as hyperaccumulators, are able to accumulate heavy metal ions in their shoots and leaves. Rhizosphere of metallophytes encompasses an exceptional environment that involves numerous heavy metal resistant bacteria. Those rhizosphere microorganisms can alter heavy metal...

Carbon aerogels and xerogels were obtained by polycondensation of resorcinol and formaldehyde in the aqueous solution using potassium hydroxide and cetyltrimethylammonium bromide (CTAB) as the catalyst. Synthesised materials were activated and their effectiveness in adsorption of heavy metals ions (nickel, copper and zinc) from aqueous...

Biosensors SPRI as a diagnostic tool in the future

Biosensors SPRI as a diagnostic tool in the future SANKIEWICZ A., PUZAN B., GORODKIEWICZ E.

Please cite as: CHEMIK 2014, 68, 6, 528–535 The biosensors are the devices which are the combination of the biologically sensitive and selective component with physicochemical detector e.g. optical. Many optical biosensors are based on the phenomenon of surface plasmon resonance (SPR) techniques and their modified version – Surface Plasmon Resonance Imaging (SPRI). SPRI biosensors are an attractive tool that can be used...

The determination of hexabromocyclododecane isomers, α, β, and γ, in industrial expanded polystyrene foams and fish tissue samples by sensitive isotope dilution technique in liquid chromatography – mass spectrometry were performed. In industrial samples γ-HBCD was the most abundant while in fish samples α-HBCD dominated.

Keywords: hexabromocyclododecane, brominated flame retardants, expanded polystyrene, food...
