Hydrogels derived from galactoglucomannan hemicellulose with inorganic contaminant removal properties

Abstract

The adsorption of Cu(ii), Cd(ii), and Pb(ii) ions onto hydrogels derived from modified galactoglucomannan (GGM) hemicellulose was studied.

Production of butanol from lignocellulosic biomass: recent advances, challenges, and prospects

“…Hexoses and pentoses could be obtained via the chemical hydrolysis of hemicellulose, however, often accompanying with the formation of 5-hydroxymethyl furfural (HMF) and furfural due to dehydration reactions. 103,104 More importantly, furan compounds can be also subjected to rehydration reactions to form levulinic acid and formic acid under acidic conditions, providing inhibitory effect on C. acetobutylicum due to the acid crash. 67,90 In addition, acetic acid is also produced through hydrolysis of the acetyl group of hemicellulose, and 10 g L −1 of acetic acid slightly increases the ABE fermentation performance, but the higher levels significantly inhibit the fermentation performance of C. acetobutylicum .…”

Novel Fluorescent Nanocellulose Hydrogel Based on Nanocellulose and Carbon Dots for Detection and Removal of Heavy Metal Ions in Water

“…Nanocellulose (NC), has unique biological adsorption characteristics and has obvious potential for the development of new green heavy metal removal technology [ 5 , 6 ]. The adsorption method has the advantages of good reusability and simple operation, and is currently considered to be the most effective and environmentally friendly method for removing heavy metals in wastewater [ 7 , 8 ]. Due to the various functional groups and three-dimensional network structure of hydrogel, it is considered to be the most promising adsorbent for removing heavy metals in wastewater [ 9 , 10 ].…”
