The concern for making our environment pollution-free is rising with each subsequent day. Among all the other measures using metal nanoparticles is also becoming a promising solution for environmental remediation. Know what metal nanoparticles are and how they aid in air, water, and soil contamination here.

What Are Metal Nanoparticles?

Metal Nanoparticles are those tiny particles of precious materials like gold, silver, and platinum. Several researches have been conducted on the effectivity of the nanoparticles of these precious metals in various sectors including medical, sensor technology, polymer preparation as well as chemical and photochemical reduction.

These nanoparticles due to their high rate of reactivity, sizes below 100 nanometers, and unique advantageous properties can work efficiently to reduce the pollutants and contaminants from polluted water, soil, and air. This makes them a perfect catalyst counterpart while making several pollution control applications.  

How Does Metal Nanoparticles Help in Environmental Remediation?

Metal Nanoparticles are delivering excellent results in managing air, water as well as soil pollution. Here is how it is bringing the change;

·       Water Purification

Using nanoparticles of these metals, especially the zero-valent iron can reduce the toxicity of various organic compounds and make them harmless for consumption or regular use. The metals with beneficial mineral content can directly interact with pollutants like arsenic, mercury, lead, etc., and mild their harmful effects.

·       Air Pollution Control

Metal nanoparticles are equally effective in reducing harmful elements from the air. They can especially interact with carbon monoxide and the oxides of nitrogen to neutralize their harmful effects. Therefore, Metal Nanoparticles are now in use in the filtration system for cleansing air while increasing the efficiency of modern-day air purifiers.   

·       Soil Remediation

The small nanoparticles of these useful metals can easily penetrate deep inside the soil, increasing its mineralization value. Instead of using chemical-based fertilizers, farmers can get the benefits of natural mineral enhancers using these metal nanoparticles. The best part is, that they can break down the toxic chemical substances spoiling the soil and make them neutralized, thus restoring the soil quality.
