V originále

Nanotextiles prepared from electrospun polyurethane nanofibers with the addition of phthalocyanines (PTC) can be used in experimental filtration device for wastewater treatment. The advantage of these filtration materials are their biocidal effects, especially PTC derivates exhibit inhibitory effect on different microorganisms including pathogens. The structure of PTC is based on four pyrrole units with metal atom coordinated in the centre of the molecule. Metal-including molecules can be determined by various spectroscopic methods. In this work zinc or titan contained in the structure of nanotextiles was detected by laser-induced breakdown spectroscopy (LIBS). For both Zn and Ti detection various emission lines were tested. Double pulse LIBS technique was optimized in order to reach high signal to noise ratio for measurements in high spatial resolution. For higher sensitivity all measurements were performed in He atmosphere. We demonstrate that LIBS offers a simple and reliable method to study the distribution of metals in nanotextiles, with spatial resolution up to 100 micrometers.
