Artis Robalds,


Ten biosorbents (pea skins (outer layer of peas), raspberry seeds, highbush blueberry pulp, blackcurrant pulp, wheat straw, seaweed Fucus vesiculosus, wheat bran, rye bran, peat and buckwheat husks) were analyzed. Characterization of biosorbents by FTIR (Nicolet iS50 spectrometer (Thermo Fisher Scientific, MA, US)), SEM (apparatus Thermo Scientific™ Helios™ 5 UX operated at 5 kV voltage and 0.1 nA current), ICP-MS (Agilent 7700 ICP-MS instrument with Mass Hunter Workstation software for ICP-MS, version B.01.03), GC-MS/MS (Shimadzu gas chromatograph GC-2010 Plus coupled with a TQ8040 mass spectrometer (Shimadzu, Kyoto, Japan)), UHPLC-MS/MS (UltiMate 3000 UHPLC system coupled to TSQ Quantiva mass spectrometer (Thermo Fisher Scientific, MA, USA) equipped with an electrospray ionization source), Py-GC/ MS/FID (Frontier Lab (Japan) MicroDouble-shot Pyrolyser Py-3030D directly coupled to a Shimadzu 2D FID/MS gas chromatography system MS-GC/GC–MS-2010 with a RTX-1701 capillary column). The nitrogen physisorption was performed using Micromeritics Tristar II equipment. In some files, the name of the biosorbent is given in Latvian or only the abbreviation is indicated, therefore please find a separate file, where names of biosorbents are given in Latvian, English, as well as the abbreviations. Title of the file - "List of biosorbents".
