摘要

This paper investigates the characterization of the tested active substrates (ASs) consisting of poly(vinyl chloride) and Aliquat 336. In all tested ASs, one of two skeleton types (fiberglass or cotton fabric) was used. In one of them, the addition of plasticizer was also tested. Scanning optical microscopy, atomic force microscopy, and contact angle goniometry were used to define the surface structure of ASs. The surface wettability of the obtained materials confirmed their hydrophilic character, which enables their use in the removal of potentially toxic element ions from aqueous solutions. The Fourier Transform Infrared Spectroscopy-Attenuated Total Reflectance method was used to identify the chemical structure of the investigated materials. Moreover, the glass transition temperature of pure ASs was determined using differential scanning calorimetry. Obtained ASs were used in three cycles of adsorption–desorption of potentially toxic elements ions from polymetallic solution, and to check the possibility of their reusability in many processes. For this purpose, their mass losses were measured during the thermogravimetric analysis. After those experiments, the mechanical properties were also performed (static tensile test).
