Abstract
Environmental health of earth is the primary determinant of the health of ecosystem, but unfortunately human activities, such as industrial development have tempered the natural composition of the environment. Worldwide, a number of industrial units are responsible for the release of effluents which are toxic and these toxins do not only enter in the environment but also tend to magnify as they travel through food chain. Amongst such toxins, manganese Mn (II) is one of the major culprits. This situation is worsening even more as the industrial progress is on its way. Recently, biosorption has come up as effective tool in which biomass of various organisms have been tested. In the present study, the biosorptive potential of algae biomass of green algae (Pithophora oedogonia) has been investigated for removal of toxic heavy metal, such as manganese Mn (II) ions. Various physico-chemical factors have been optimized for biosorptive capacities of sorbates by sorbents. Optimum pH was found to be 4 and optimum temperature was 30OC for manganese Mn (II). Various adsorption models were elucidated to data, such as Langmuir, Freundlich and Temkin isotherms whereas Freundlich model was found to be fittest showing multilayer sorption. Pseudo-second order kinetic model was also found to fit for this study with regression coefficient value of 0.97. Additionally, Fourier Transform Infra-red Spectroscopic studies (FTIR) indicated various electronegative functional groups on the surface of green algae (Pithophora oedogonia) which could possibly offer the binding sites for cations under investigation.
