here the role of some of nanoparticle in environment cleanup is given.nanoparticles are possesing the power of cleaning the water and air also it can act assensor too

1. Nanotechnology in
Environment
Megha Parihar
CUH

2. Air pollution control using nanoparticles
● Catalyst
● Nano-structured membranes

3. Carbon Nano Tubes (CNTs) for Air pollution
● Absorption of gases

4. Use of CNT for removal of CO2 and CO
Polyethyleneimine (PEI)
Ethylene diamine (EDA)
3 - aminopropyltriethoxysilane (APTS)

5. Use of CNTs for NOX and SO2
● CNTs are highly selective, stable
● Capable of adsorbing gas particles
● Gas ionization process

6. Nanobioremediation
● High surface area
● Adsorption of heavy metals

7. Why nanoparticles as bioremediation
● Environmental cleanup
● Unique properties for remediation of pollutants
● Nanosize to diffuse into contamination zone and degrade pollutants
● They can form complex

8. Nanoscale zero-valent iron (nZVI)
● Properties of catalysis
● Mitigate various pollutants
The nZVI undergo following reaction in groundwater corrosion
Fe2+ further transformed to Fe3+ ion by following oxidative transformations

9. Nanoscale zero-valent iron (nZVI)

10. Single-enzyme nanoparticles in bioremediation

11. Green or biogenic nanoparticles
