Synthesys
and investiganion of properties of silica gel sorbent modified superbranched
poly(methyldichlorsilylpropyl)carbosilane with molecular prints of
2,4-dichlorophenoxyacetic acid
Abstract
The new sorbent for selective sorption
2,4-dichlorophenoxyacetic acid (2,4-D) from water solutions was synthesized.
This material is silica gel modified superbranched
poly(methyldichlorsilylpropyl)carbosilane with molecular prints 2,4-D (SG-MP).
The specific surface area of this sorbent was estimated. The sorption of 2,4-D
was studied in the static mode. On the basis of analysis of adsorption
isotherms it is shown, that SG–MP possesses ability to molecular recognition
2,4-D. On an example of structurally related compounds the selectivity of the
synthesized sorbent was estimated.
