Modern methods of analysis and instruments measuring sorption properties of magnetic sorbents

Abstract

Introduction. Research in a field of new sorption materials obtaining have been presented in this article. These sorbents have magnetic properties and they can be used for water purification from ions of heavy metals (HM), petroleum and petroleum products (PP). Compositional sorption material (CSM) has been made with the use of ferritized galvanic sludge (FGS) as a magnetic component and paraffin as a binder substance. Materials and methods. The following objects of the research were chosen in this work: industrial waste - galvanic sludge (GS), FGS, paraffin. Modern methods of the research have been used at work implementation: photometry, IR-spectrophotometry, scanning electron microscopy. Obtaining accurate and reliable results of the experiment were provided by the use of standard methods, established in federal environmental regulatory document (PND F), verifiable measuring instruments and standard samples. Results. FGS after a thermal processing has sorption properties in relation to ions of heavy metals Fe2+, Fe3+ and Cu2+. The material CSM can adsorb petroleum and PP. Discussion and conclusions. The sorption materials on the basis of industrial waste - GS were obtained and studied. These sorbents have magnetic properties which will be useful at water treatment; a saturated material can be extracted from a purified environment by magnetic separation.
