Abstract: One of the worldwide environmental issues is water contamination by toxic heavy metals such as lead (Pb), zinc (Zn), copper (Cu), arsenic (As), cadmium (Cd), chromium (Cr), nickel (Ni) and mercury (Hg). These heavy metals are most commonly found in industrial wastes, and it has potential impacts on the ecosystem and human health. In order to remove these heavy metals from synthetic water, an economically effective adsorbent is required. Data required for the study is extracted from a senior P.G. student with topic “Removal of Cadmium From Pharmaceutical Industry by Using Adsorption Techniqueâ€. This study gives insight on one of the heavy metal removal technique i.e. Adsorption, using various adsorption isotherms such as Langmuir, Freundlich, Temkin, Thomas, Banghams adsorption isotherm equations which were derived from the basic empirical equations, and used for calculation and analysis of the data extracted from a dissertation report. This study highlights the best fit isotherm for the given set of data for one of the heavy metal Cadmium wherein the Bangham’s Isotherm with 0.9487 value of coefficient of correlation, followed by Freundlich Isotherm with 0.9237 and Temkin Isotherm at 0.853.
