Photo-degradation of four different organic dyes in green synthesized chromium nanoparticles by leaf extracts of ocimum basilicum-lamiaceae (Thiru neetru pathilai)

Nanotechnology is an escalating field, which has a growing impact in each and every sector. There are many ways for synthesizing nanoparticles but biosynthetic route of nanoparticle synthesis is emerging as a new and safer alternative to the conventional methods. Ocimum basilicum is an age old herb native to Southeast Asia and Central African countries. These plants are generally known to be used in different cuisines world-wide. The aroma emitted from the leaves and the twigs of the fresh and dried plants are well known to have insect repellent property. Estragole, citronellal, limonene and nerolidol are the natural volatile compounds present in the basil leaves which acts as repellents. This plant is also widely used as a scent through which it netted its title Queen (basileus) of aromatic herbs. In present study the Green synthesis of Chromium oxide nanoparticles have been synthesized by Ocimum Basilicum-Lamiaceae (Thiru Neetru Pathilai).This method is completely a green method, free from toxic and harmful solvent. The formation of chromium oxide nanoparticles confirmed by UV-Visible spectrophotometer (UV-Vis), and Fourier transform infrared spectroscope (FTIR). The FTIR measurement was carried out to identify possible functional contain the natural product, responsible for efficient stabilization of chromium oxide nanoparticle.
