I am doing a project proposal where I have to analyze and compare three methods to remove harmful metals from water and choose the best one among them after comparing them with similar parameters. I would be also thankful if some could give a link or PDF to potential articles.
Please, refer to the following links :

For adsorption process the main factors that affect this process are pH, As the pH of the adsorbent material decreases, ion exchange becomes the dominant process for heavy metals retention, The pHpzc plays a key role in the adsorption process. When the pH > pHpzc, the surface of the adsorbent material becomes dominantly negatively charged and the adsorption of metal ions will be facilitated by electrostatic attraction, and finally The high surface area of any material is a positive attribute when they are being used as adsorbent. You can find more detail in attached file chapter three and four.
I hope this detail useful for your project and good luck.
Hello
One of the easy ways to precipitate heavy metals
1- Sedimentation with the associated organic materials
The best way to get rid of nutrients and heavy dissolved elements is to use biological therapy
As the use of aquatic plants, including duck herb plants, where it works to absorb the body's need and the excess can be absorbed on the surface of the body and in the case of food safety, the feed is given to farm animals and the other way around, green manure is used for forest trees.
