Abstract:

In this work we are suggesting a method to reduce the amount of metal nitrates used in industrial and agricultural applications with the help of photocatalytic effect. Also, the work discusses how the residual amount of metal nitrates in the soil can be made useful through the same effect. Though metal nitrates like ferric nitrate and nickel nitrate shows characteristic absorption in the UV region, what we observed is an enhancement in this UV absorption when we treated this metal nitrates with Titania Tenorite nanocomposite due to its photocatalytic action. This absorbance enhancement property is an indication of increase in concentration of the metal nitrates in the solution with light irradiation. The increase in M–OH bonds owing to the action of the nanocomposite in the presence of light is the reason by which metal nitrates absorption increases. In precise a tiny amount of metal nitrates is needed for any practical use as it can automatically increase its concentration in presence of the nanocomposite by photocatalytic reaction. This will reduce the disposal of unwanted amount of metal nitrates into the surrounding especially water bodies. Also, the residue amount in the soil can act as UV absorbers. Thus, the combination of the metal nitrates with the nanocomposite can be made used for environmental remediation where the metal nitrates are used in large quantities.
