ADSORPTION:
|
Adsorbents used today for water treatment, like activated carbon and carbon nanotubes, are impractical for large scale water treatment as a result of their relative higher cost.
The primary criteria that should be used to determine the feasibility of using an adsorbent for water treatment should be low cost-to-benefit ratio. Since most adsorbents are neither economically viable, efficient, nor practical for large scale use, a new adsorbent must be optimized to meet the devastating global water demand. |
CASEIN:

CASEIN NANOPARTICLES
Removing Heavy Metals
Casein nanoparticles were created for their simple preparation, high surface area, and surface reactivity. and were able to remove 45% of Nickel(II) as shown in the graph. In addition, the concentration of Ni used was much higher than that in natural waterways, further demonstrating casein's ability to remove heavy metals from water.
The casein nanoparticles successfully adsorbed the Ni because of casein's negative charge in water. This is due to the fact that casein has a low isoelectric point of 4.6 and is a phosphoprotein. Thus, the anionic surface of casein attracts the positively charged Ni ions to its binding sites. |
CYCLODEXTRIN:
A promising adsorbent
Cyclodextrin is a sorbent used to retain odors because of its hydrophobic cavity

CYCLODEXTRIN MODIFIED ZEOLITES

It is clear both casein and CDMZ are phenomenal adsorbents of water contaminants. Thus, it can be established that these adsorbents are eco-friendly and cost-effective means for efficiently treating polluted waters. In the near future, AQUASORB would like to implement these novel adsorbents for treating local water systems. We will keep you updated!
