A REVIEW ON VARIOUS TECHNIQUES AND PARAMETRS SIGNIFYING PURITY OF WATER
Abstract
Abstract
Â
Water is the source and basis of all life. Safe drinking water is essential to humans and other life forms even though it provides no calories or organic nutrients. Access to safe drinking water has improved over the last decades in almost every part of the world, At room temperature, it is a tasteless and odorless liquid, nearly colorless with a hint of blue. Many substances dissolve in water and it is commonly referred to as the universal solvent. Because of this, water in nature and in use is rarely pure and some of its properties may vary slightly from those of the pure substance. Drinking water must be purified. A brief idea regarding purification methods includes Distillation, Deionization, Reverse osmosis, Activated carbon filtration; Ultraviolet oxidation, Electro dialysis etc are described. Water has some unchanged parameters which can be use to check purity. It includes PH, turbidity, salinity, hardness etc. various analytical methods are now available to determine such parameters and checking of purity.
Analytical methods include colourimetry, uv spectroscopy, titration, mass spectroscopy, titration and many more.
