Vattenrening med hjälp av protein-nanomaterial: HPLC-analys av borttagning av naproxen och diklofenak från vatten (Swedish)
Abstract [sv]

I det här projektet undersöktes nya aerogelmaterial som baserats på den nyligen etablerade teknologin med protein-nanofibriller, PNF, för vattenreningsapplikationer. Tidigare forskning har rapporterat användning av PNFs tillverkade av vassle. I denna rapport testades fyra nya aerogelmaterial: bondböna (fava), ärta, potatis och soja. Materialens effektivitet i att avlägsna föroreningarna diklofenak och naproxen testades. Förändringen i föroreningskoncentration analyserades med hjälp av högupplösande vätskekromatografi, HPLC, med UV/VIS-detektor. Testen visade att alla material kunde avlägsna föroreningarna med en effektivitet på minst 60 %, men att material baserade på bondböna och soja utmärkte sig något jämfört med de andra. Denna rapport fungerar som en utgångspunkt för vidare analys av effektiviteten hos de nya aerogelmaterialen.

Abstract [en]

In this project, the water purification applications of new aerogel materials developed based on the recently established protein nanofibril, PNF, technology were investigated. Previous research has reported the use of PNFs made from whey. In this report, four new aerogel materials were tested: fava, pea, potato, and soy. The materials were evaluated for their efficiency in removing the pollutants diclofenac and naproxen. Changes in pollutant concentration were analysed using high performance liquid chromatography, HPLC, coupled with a UV/VIS-detector. The tests showed that all materials were able to remove the pollutants with an efficiency of at least 60%, with fava- and soy-based materials performing slightly better than the other materials. This report serves as a starting point for further analysis of the efficiency of the new aerogel materials.
