Abstract

Physico-Chemical Analysis of Water of Jaipur City and its Defluoridation by Using Brick Powder and Marble Slurry Powder: a Green Approach to Utilize Industrial Wastes

Author(s): Naresh Kumar, Nidhi Bansal and Sanjay K Sharma

‘Green Chemistry’ provides various tools and techniques including the ion-exchange, adsorption, reverse osmosis, precipitation and many more as some usual means of defluoridation. In present study, fluoride ion concentrations in water were determined spectrophotometrically at 570 nm by employing SPANDS method. Then Brick powder (BP) and marble slurry powder (MSP) were used as adsorbents in defluoridation of water. Use of these wastes as adsorbents serves two purposes at the same time, one is low cost and eco-friendly defluoridation and other one is waste management. Brick powder (BP) and marble slurry powder (MSP) are wastes found in brick kiln and marble industrial area situated nearby Jaipur City of Rajasthan state. The dose of adsorbents, contact time and concentration of fluoride ions will be discussed with their interdependence. For this study, water sample taken from different locations of Jaipur city were studied. It was found that the defluoridation capacity of brick powder is good than the marble slurry powder.
