Water treatment |
| abstract |
The present invention relates to a method for removing metal ions from wastewater, the method comprising providing plant-derived anionic nanofibrillar cellulose; performing a purification treatment comprising adsorption of positively charged metal ions contained in the wastewater onto the nanofibrillar cellulose; separating the used plant-derived anionic nanofibrillar cellulose from the wastewater; and recovering the treated wastewater. The invention also relates to the use of plant-derived anionic nanofibrillar cellulose for removing metal ions from waste water. |
