Physico-Chemical Analysis of Wastewater Samples Collected From the Chemistry Laboratory at Kohima Science College, Jotsoma and Model Christian College Kohima ESP Journal of Engineering & Technology Advancements  3(3): 8-14.

Abstract:

Wastewater especially from the chemistry laboratory contains several toxic chemicals that are harmful to the environment although the quantity of wastewater produced by the laboratory is relatively small. This study is aimed at analyzing the physicochemical parameters of wastewater collected from the chemical laboratories in Kohima Science College Jotsoma, and Model Christian College, Kohima using standard analytical procedures. The samples collected were analyzed for various physicochemical parameters like pH, Electrical Conductivity (EC), Salinity, Total Dissolved Solids (TDS), Oxidation-Reduction Potential (ORP), Iron, Sulfate, Phosphate, Nitrate, Dissolved Oxygen (DO), Potassium, Sodium, Total Hardness (TH), Alkalinity, Chloride, and Calcium, and the results were compared with the standard prescribed by the BIS and WHO for drinking water. The result obtained from the physicochemical analysis of water samples shows that some parameters are found within the permissible limit of BIS and WHO standards, while a few parameters were found beyond the permissible limit of BIS and WHO standards posing a threat to the natural environment it has been released in without treating it.
