Physico-Chemical and Optical Examination of Water Stored in Copper Vessels

Abstract

Storage of water in copper vessels is traditionally followed in past and many reports have been published about the antibacterial growth in copper vessel. It is essential to determine the water purity for drinking purposes in daily life through low cost approach. In the present work an attempt has been made to investigate the effect of storage of different drinking water in copper vessel for two week. The corresponding values of pH and TDS meter for different waters were recorded and analyzed. The optical properties such as UV-Vis and Raman studies along with physio-chemical parameters like pH and TDS were analyzed for 3weeks against different water sources kept in copper vessel. The Raman spectra provide information for different water sources. Similarly the UV-Vis spectroscopy provide the peak variation for different waters, however the effect of days and copper concentration analysis are in investigation. The Results obtained in this study reveals that water stored in copper vessel reduces the TDS level of bore water Tirunelveli and maintains its pH at 8.0 after 2 weeks. The bore water in Krishnan kovil (virudhunagar district) shows no variation in TDS after 1 week, but in 2nd week there is sudden decrease in TDS from 1050 to 944ppm and pH level decreases to 8.3 showing alkaline nature. Throughout the experiment we have noticed that the colour of copper vessel changes in case of bore water. For variation in studies we have also studied the pH and TDS of Drinking water at Kalasalingam Academy of Research and Education. There is no change in colour of copper vessel and TDS and pH remains same up to one week, but in second week TDS increases to 100ppm while the pH remain constant at 7.4. These studies will help future researcher for designing of copper vessels and will help them to analyze the Physio-chemical studies of water. Moreover the chemical mechanism and reaction between copper vessel and leaching out of copper into water data base will be generated in future based on UV and Raman studies.
