Removal of Acid-soluble Lignin from Biomass Extracts Using Amberlite Xad-4 Resin
This paper describes a method for the removal of acid-soluble lignin from acid-hydrolyzed hemicelluloses extracted from a mixture of northern US hardwood chips, by using Amberlite XAD-4 resin, which was shown to remove 100% of furan derivatives and 90% of acid-soluble lignin. Subsequent fermentation of the resin-treated hydrolyzates gave ethanol yields as high as 97% of theoretical and showed a...
متن کاملFabrication of Unique Magnetic Bionanocomposite for Highly Efficient Removal of Hexavalent Chromium from Water
Biotreatment of hexavalent chromium has attracted widespread interest due to its cost effective and environmental friendliness. However, the difficult separation of biomass from aqueous solution and the slow hexavalent chromium bioreduction rate are bottlenecks for biotechnology application. In this approach, a core-shell structured functional polymer coated magnetic nanocomposite was prepared ...
متن کاملApplication of modified bentonite using sulfuric acid for the removal of hexavalent chromium from aqueous solutions
Background: Environmental contamination by chromium (Cr) has become an important issue due to its adverse effects on human health and environment. This study was done to evaluate the application of modified bentonite using sulfuric acid as an adsorbent in the removal of hexavalent Cr from aqueous solution. Methods: Adsorbent features were determined using x-ray diffraction (XRD), fourier transf...

Removal of Pb(II) from aqueous solutions by using dioctyl sodium sulphosuccinate-EDTA modified Amberlite XAD-7HP resin
The removal of Pb(II) from aqueous solutions by using modified Amberlite XAD-7HP resin has been studied. The resins have been prepared by complete mixing of Amberlite XAD-7HP resin with anionic surfactant-dioctyl sodium sulphosuccinate (DOSSS) and EDTA-disodium salt (Chelating agent) in an aqueous solution. SEM studies revealed the morphological observations of the unloaded adsorbent and thereb...
