Beschreibung

Allgemeine Beschreibung

Supelite DAX-8 is a nonfunctionalised resin with strong hydrophobic organic matter endorsed to humic and fulvic acids. It is also referred as polymethylmethacrylate resin.

Anwendung

Adsorberharz mit mittlerer Polarität für Verbindungen bis MW = 150000. Meist genutzt für die Adsorption von Fulvin- und Huminsäuren, Behandlung von Abwasser aus der Papiergewinnung und Entfernung von Alkohol, Tensiden und Farbstoffen aus Proben.

Supelite DAX-8 was used as an absorbent in:

• HPLC-SEC fractionation system
• column chromatography
• extraction procedure and extracts were analysed using Cary Eclipse fluorescence spectrophotometer

Angaben zur Herstellung

DAX-8 is a salt imbibed resin, which requires some preparation prior to use. In the protocol below, you may use methanol in place of ethanol.

• First, rinse the adsorbent resin with 2-3 bed volumes (BV) of distilled water.
• Soak overnight in 2 BV of 95% ethanol.
• After soaking, the resin is introduced into the column and rinsed with an additional 2 BV of 95% ethanol.
• Rinse with 2 BV of distilled water to displace the ethanol, followed by 1 BV of 4% (w/v) sodium hydroxide, 2 BV of distilled water, 1 BV 4% (v/v) hydrochloric acid, and finally by distilled water until the pH of the eluent becomes neutral.
