Changes of parameters of mixed monolayers
on the basis of photosensitive crown ether in the presence of silver ions
Abstract
The use of the achievements of
colloid-chemical methods in combination with other fields of chemical sciences
leads to the creation of new nanoscale systems for chemosensorics. Mixed
monolayers consisting of a new chemosensory amphiphilic dithia-18-crown-6,
which contains a dye of a series of 4-alkylpyridine with polyvinyl stearate at
the water-air interface were obtained and studied. The influence of various
concentrations of silver ions on such mixed monolayers has been studied. A
promising method for the detection of silver ions in water using these
nanoscale systems based on chemosensory amphiphilic dithia-18-crown-6 is
proposed.
Key words:
dithia-18-crown-6, polyvinyl stearate, silver ions, monolayers.
