Methyl red (2-(N, N-dimethyl-4-aminophenyl) azobenzene carboxylic acid) incorporated domestic wastewater treated upon (Ag-Pb) nanosynthesis

Synthetic dyes are one of the dangerous products discharged in the water. It causes coloration and contamination of water. In wastewater treatment, the nanoparticle is used for decolourisation and to remove the pollutants. This can be achieved by using the metal nanoparticle. The main objective of the work is to treat the contaminated water using the nanoparticle synthesised by the chemical method. Here we use silver and lead nanoparticle, which is synthesised by the chemical synthesis method. The synthesised nanoparticle is characterised by UV–visible spectroscopy and FTIR (Fourier transform infrared spectroscopy). The nanoparticle formation confirmed is done by using the UV–visible spectroscopy. The functional groups of the silver nanoparticle are determined using the peaks observed in the FTIR at 3273.332 cm⁻¹ and 1635.348 cm⁻¹ which correspond to C-H stretching and C–C stretching. For lead nanoparticle, the peaks at 3303.458 cm⁻¹ and 1635.465 cm⁻¹ correspond to O–H stretching and C-H stretching. Here, the sedimentation of the pollutants occurs. This treated water can be used for further purpose such as in the agriculture field.
