Immobilisation of Humic Substances Using Plasma Modifications

Original language description

This paper is focused on the way humic substances are immobilized on polypropylene (PP) nonwoven fabrics. In order to fixate humic substances, the PP nonwoven fabric was modified in a volume of nonthermal atmospheric pressure dielectric barrier discharge(DBD) under defined conditions. Unmodified PP fabric was used as a reference sample. Both modified and unmodified samples were dipped in aqueous solution of potassium humate, dried and consequently acidified in 7 % acetic acid. Then the samples were washed in water and dried. Aqueous solution of cadmium salts was filtrated through the treated fabric, the content of cadmium in the solution was monitored using ICP-OES analysis. Efficiency of the PP plasma modification was proved by the XPS analysis and adhesion of humic substances to fibers using SEM analysis.
