Development Of Polysaccharide Derived Carbon Aerogels For The Remediation Of Pharmaceuticals Contaminated Water

The preparation of eco-friendly carbon aerogels via ambient pressure drying using natural polysaccharides, mainly carrageenan, pectin, sago, guar gum, konjac gum, xanthan gum, psyllium husk and sodium alginate have been conducted. The adsorption performance for the remediation of pharmaceutical comp...
