Kaith plant leaves (Feronia limonia) were investigated as a low cost and effective adsorbent for the removal of fluoride ion from aqueous solution. The effects of initial fluoride concentration, initial pH and contact time and adsorbent dose on the adsorption of fluoride on Kaith plant leaves were investigated. The amount of fluoride adsorbed was found to vary with initial solution pH, Kaith plant leaves dose, fluoride concentration and phases contact time. The Langmuir and Freundlich adsorption models were evaluated using the experimental data and the experimental results showed that the Langmuir model fits better than the Freundlich model. The adsorption rate data were analyzed according to the pseudo-first order kinetic and pseudo-second order kinetic models. It was found that kinetic followed a pseudo-second order model.

The photocatalytic degradation of Evans blue (EB) has been studied under visible light in the presence of nanocrystalline nickel doped cobalt (II) oxide as a photocatalyst. Nickel-cobalt (II) oxide was synthesized by using Sol-gel technique. The photocatalyst was characterized by Field Emission Scanning Electron Microscopy (FESEM), Energy-dispersive X-ray spectroscopy (EDX), X-ray Diffraction (XRD), Fourier-transform infrared (FTIR) and High-resolution transmission electron microscopy (HRTEM). Effect of various working parameters like pH, concentration, amount of nickel doped and undoped cobalt (II) oxide, dose of dopants, light intensity etc. on the rate of degradation of Evans blue was also investigated. On the basis of observations, a suitable mechanism for the photocatalytic degradation of Evans blue dye has been proposed.

Green synthesis of silver nanoparticles is one of the promising branches of nanotechnology for applications in different biomedical fields. In the present investigation, methanol extract of Tinospora cordifolia root were used as reducing agent. Then the silver nanoparticles are characterized using UV-Vis, SEM, XRD, TEM and FTIR spectroscopic techniques. The functional biomolecules responsible for the reduction of the silver ions and the capping of the silver nanoparticles by the plant extract Tinospora cordifolia were identified by the Fourier transform infrared spectroscopy (FTIR) analysis. The TEM analysis shows that the silver nanoparticles with an average size of 100 nm. X-ray diffraction analysis showed that the particles were crystalline in nature.

Pithampur Industrial area also known as “Detroit of India”. There are tremendous types of industries in Pithampur Industrial area. Due to industrialization, the quality of water may always sensitive, because some industries do not have proper treatment system and they discharge untreated water in outer their premises. In this study number of samples and parameters were analyzed. This study is helpful for many stakeholders to make proper planning.
