Treating waste water using natural substances: Sol gel immobilization of humic and fulvic acids using microfibrillated cellulose

Microfibrillated nanocellulose has large pore sizes (100 to 1000 nm) and provides a large surface area of contact with surroundings. When manufactured by acid hydrolysis of substrate i.e. wastes from wine and sugar industry by acetobacter xylinum, it is lignin free and has a more intricate structure. (nanocellulose obtained as water suspension).

Humic acids and fulvic acids - Sol gel immobilization

Humic acids and fulvic acids have been known to remove heavy metals, toxins, viruses and other inorganic matter and convert them to organic matter. These acids can be obtained from dried cowdung by mild alkaline treatment and filtration.
