Study on the Adsorption of Nickel (II) in Water by Modified Dried Duckweed
The paper uses dry duckweed before modification and dry duckweed modified with formaldehyde and concentrated sulfuric acid as adsorbents to adsorb and remove nickel ions in water. The results show that the removal rate increases with the increase of temperature. When the reaction time is 70 min, the...

description | The paper uses dry duckweed before modification and dry duckweed modified with formaldehyde and concentrated sulfuric acid as adsorbents to adsorb and remove nickel ions in water. The results show that the removal rate increases with the increase of temperature. When the reaction time is 70 min, the concentration of nickel is 20 mg/L, and the dosage is 0.05 g, the removal rate of nickel ion by the duckweed adsorbent is 35.01%. When the reaction time is 30 min, the concentration of nickel is 20 mg/L, and the dosage of modified duckweed is 0.1 g, the removal rate of nickel ion by the modified duckweed adsorbent is 44.85%. The adsorption effect of the modified adsorbent is obviously improved, which provides a basis for the application of duckweed in the adsorption of nickel - containing wastewater. |
