Preparation
of reagent indicator papers with silver triangular nanoplates for the purposes
of chemical analysis
Abstract
An impregnation method of preparation of reagent indicator papers with
silver triangular nanoplates (TNP) was developed. Conditions of the modified
papers preparation (type of paper, way of TNP putting, conditions of drying)
allowing for acceptably uniform distribution of TNP were chosen. Spectral
characteristics of prepared materials were studied. Presence of an intense TNP
surface plasmon resonance band in diffuse reflectance spectra of the modified
papers which is linearly related to the content of TNP in the samples as well
as lability of its position and shape in presence of some substances gives rise
to prospects of using prepared materials as test-tools in the chemical
analysis.
Key words: reagent indicator paper, silver triangular nanoplates,
surface plasmon resonance, test-tool, diffuse reflectance spectroscopy.
