Determination
of polyhexamethyleneguanidine hydrochloride using gold nanoparticles and
polyurethane foam
Abstract
The adsorption of gold nanoparticles stabilized by sodium citrate on
polyurethane foam (PUF) in the absence and presence of
polyhexamethyleneguanidine hydrochloride (PHMG), depending on time of the phase
contact, pH and concentration of nanoparticles was investigated. The
opportunity of PHMG determination using gold nanoparticles, PUF and the diffuse
reflectance spectroscopy was shown (Cmin = 0.008 µg mL-1). PHMG determination
in the model mixtures based on mineral and tap water and water from the pool was
carried out.
Key words: polyhexamethyleneguanidine hydrochloride, sorption, polyurethane
foam, gold nanoparticles, diffuse reflectance spectroscopy
