This presentation describes the removal of lead contents from the waste stream using Water hyacinth. In this way, the elimination of water hyacinth occurs corresponding to the removal of Lead ions.

2. Nano Adsorbents
• Nanoparticle are particles between 1 and 100 nanometres
• Nano particles are used to remove pollutants and so called nano-
adsorbents
• Remove new emerging pollutants even at low concentration i.e. μg/L
• Particularly used to remove the Heavy metals
• Hence, used up in Wastewater treatments

3. Adsorption vs Absorption
• Adsorption is the adhesion of atoms, ions or molecules from a gas,
liquid or dissolved solid to a surface.

4. Water hyacinth
• Eichhornia crassipes, commonly known as common water hyacinth,
is an aquatic plant native to the Amazon basin
• Invasive species outside its native range
• Used in Bioremediation
• Uptakes Heavy metals e.g., Cyanide

5. Duck weeds
• Also known as water lenses and it is a type of weed
• These plants have a simple structure, lacking an obvious stem or leaves.
• Duckweeds tend to be associated with fertile, even eutrophic conditions.
• Duckweed is a good candidate as a biofuel
• produces five to six times as much starch and does not contribute to global
warming.

6. Aquatic weeds as Nanoadsorbents
• The Aquatic weeds were synthesized by Sol-gel method for surface
medications.
• On surface modification, it shows higher adsorption
• Characterized by FTIR, Brunauer, Emmett and Teller (BET) surface area
analyzer, SEM, and TGA
• Adsorption should be tested in different pH of solution, adsorption dosage,
metal ion concentration
