Equations that calibrate XRF to ICP-OES were determined, as a biosorbent strawberry, blackcurrant and raspberry seeds after supercritical CO2 extraction were used. ICP-OES showed a better precision and lower detection limits than XRF. The latter technique is cheaper, requires minimal sample preparation and gives faster results. Linear regression of the data gave almost 1:1 correlations without additional correction (for Cu r2 = 0.9998, Mn r2 = 0.807, Zn r2 = 0.979). Calibration and quantification of intensities of XRF was obtained using ICP-OES measurements after samples digestion with HNO3 in a microwave system. High positive correlations were estimated for Cu, Mn, Zn. It was demonstrated that XRF technique can be used together with other well established techniques (ICP-OES) to produce quantitative data from biosorption studies. Elaboration of cheap and quick analytical methodology is an important aspect in development of new processes and products based on biosorption process.<\/jats:p>","DOI":"10.3390\/molecules23082076","type":"journal-article","created":{"date-parts":[[2018,8,20]],"date-time":"2018-08-20T11:23:06Z","timestamp":1534764186000},"page":"2076","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Using XRF and ICP-OES in Biosorption Studies"],"prefix":"10.3390","volume":"23","author":[{"given":"Katarzyna","family":"Chojnacka","sequence":"first","affiliation":[{"name":"Department of Advanced Material Technologies, Faculty of Chemistry, Wroc\u0142aw University of Science and Technology, Smoluchowskiego 25, 50-372 Wroc\u0142aw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mateusz","family":"Samoraj","sequence":"additional","affiliation":[{"name":"Department of Advanced Material Technologies, Faculty of Chemistry, Wroc\u0142aw University of Science and Technology, Smoluchowskiego 25, 50-372 Wroc\u0142aw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u0141ukasz","family":"Tuhy","sequence":"additional","affiliation":[{"name":"Department of Advanced Material Technologies, Faculty of Chemistry, Wroc\u0142aw University of Science and Technology, Smoluchowskiego 25, 50-372 Wroc\u0142aw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8084-9642","authenticated-orcid":false,"given":"Izabela","family":"Michalak","sequence":"additional","affiliation":[{"name":"Department of Advanced Material Technologies, Faculty of Chemistry, Wroc\u0142aw University of Science and Technology, Smoluchowskiego 25, 50-372 Wroc\u0142aw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0353-4644","authenticated-orcid":false,"given":"Ma\u0142gorzata","family":"Mironiuk","sequence":"additional","affiliation":[{"name":"Department of Advanced Material Technologies, Faculty of Chemistry, Wroc\u0142aw University of Science and Technology, Smoluchowskiego 25, 50-372 Wroc\u0142aw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcin","family":"Mikulewicz","sequence":"additional","affiliation":[{"name":"Department of Dentofacial Orthopeadics and Orthodontics, Division of Facial Abnormalities, Medical University of Wroc\u0142aw, ul.
