"Phthalocyanine derivates (PTC), macrocyclic compounds with basic structure consisting of four pyrrole units with metal atom (Cu, Ag, Zn) coordinated in the centre of the molecule, could be utilized in various environmental technologies due to inhibitory effect on different microorganisms including pathogens. The advantageous possibility is application of PTCs added to the filtration system for wastewater treatment. The defined amount of PTC (maximum 1%) is mixed with polyurethane and electrospinning process is used for preparation of polymer nanofibres. Electrospun polyurethane nanofibers incorporating with PTC on the spunbond layer form nanotextile which is used in experimental filtration device. This arrangement provides elimination or complete removal of present microorganisms. The aim of this work was observation of various metals and their concentration level before and after the filtration tests. The permeability of the filtration nanotextile membrane was also studied by using model metals solutions. Different samples of nanotextiles prepared for the experiment were analysed and after decomposition or extraction the metal occurs in PTC was determined. For the determination of metals high-resolution continuum source atomic absorption spectrometry was used." .
