ABSTRACT:-
Dental fluorosis is one of the predominant health problems among peoples consume fluoride contaminated well water in rural areas of Tirupattur district, Tamil Nadu. Hence, present study was aimed to synthesis the copper nanoparticles (CuNPs) by using flower extract of Pongamia glabra and evaluation of its fluoride removal efficacy in ground water collected from regions near Tirupattur, because CuNPs attained much attention by their diverse applications. CuNPs were synthesised by molar ratio method and structure and morphology of the CuNPs were characterized by various spectral studies such as UV, FT-IR, SEM and DLS. Agar well diffusion method was followed to analyse the antimicrobial effect of CuNPs. IS 3025 (Part 60) 2008 method was followed to measure the fluoride quantity in collected ground waters. The UV-Vis measurement showed the peak at 340-360 nm, whereas FTIR characteristic peaks of metal-oxygen (Cu–O) were confirmed in the range 506 cm-1 and Cu–O–H bonds led to bending absorptions in the region 875 cm-1. The reduction (3450 cm-1 to 3424 cm-1) in the absorption band reveals the formation of CuNPs. The synthesized CuNPs possess the spherical shapes and high content of copper as confirmed by SEM. The synthesised copper nanoparticles have relatively good antimicrobial property by inhibiting the wide spectrum of microbes such as several pathogenic Gram positive and Gram-negative bacteria as well as the growth of some fungi. After treatment with CuNPs in the concentration of 1 mg/100ml, the high fluoride content in the ground water reduced significantly by the reduction of 85-95 % levels. The results revealed that CuNPs can be used as a potent source to reduce the fluoride content in drinking ground water; thereby we may suppress the effects of dental fluorosis in the affected regions.
