India, Being a Developing Nation, Has Undergonerapid Industrialization In the Last Few Decades. With the Enormous Growth Andexpansion of Technology, a Serious Problem of Environmental Pollution Hascropped Up, Which Has Now Become a Major Threat For Vegetation and Animal Life.In Various Forms, Cruel Hands of Pollution Are Throttling the Living Humanism.Water, Is Being Contaminated More and More By the Toxic Metals and Pesticidesand Is Responsible For Water Pollution. Thus Pollution Is an Unavoidableconsequence of Industrialization and the Ultimate Cause of the Poorer Globalenvironmental Quality. Although some of the Metals Are Essential Nutrients Forplants and Animal Metabolism (Glucose Metabolism, Amino Acid Metabolism), Yetaccumulated at High Levels, These Can Cause Serious Disorders and Diseases(Nausea, Skin Ulceration, Lung Cancer Etc.) and They Ultimately Become Lethal.Thus Metals Like Nickel, Iron, Manganese and Mercury Pose Potential Danger So,It Is Necessary to Develop a Rapid and Accurate Analytical Method For Theirdetermination. Quantitative Analysis Often Involves the Spectrophotometricresolution of Mixtures of Two Components With Partly or Completely Overlappingspectra – the Greater the Extent of Overlapping the More Difficult Theresolution Is Rendered. the Multicomponent Linear Additive Model Is Frequentlyused In Resolving Mixtures. Its Application Requires Assuming the Measuredresponse to Be Made Up of the Sole Contributions of the Known Components of Thesample. ...
