Use of Column of Ferronia Elephuntum Fruit Shell Substrate for the Adsorption of Fe[Ii] and Mn[Ii] Metal Ion From Aqueous Solution

Abstract

Meagre quantity of water, which is available for human use is also getting contaminated because of industrialisation, urbanisation and population exhaust. The major contaminants responsible for water pollution are as follows inorganic pollutant and toxic metals, sediments, oxygen demanding wastage , radioactive substances , thermal pollutants , pesticides form wastage and fertilizers auto exhaust as water pollutants , organics , synthetic detergents , diesease causing agents,plant nutrient, biological pollutant and suspended matter . Salt of various heavy metals and other potentially hazardous material are being discharged in increasing amounts into the aquatic environment. Water containing significant concentration of some of the heavy metal ion are toxic to human being , animals as well as aquatic organisms. The toxicity of some heavy metal ions even at the trace level as being recognised with respect to the public health for many years . Metal such as Hg, Pb, Cd, Cu, Cr fall under this categories. Many metals have been evaluated as toxic to aquatic life over certain threshold toxicity level. Exposure to heavy metal toxicity can result from every facet of natural activity such as agriculture , mining, transport energy and industry. Continue release of metal wastage into the environment has been justified on the basis of dilution to undetectable level or to the level below the threshold toxicity level in the receiving water body. The uncontrol growth of industrialisation in the world is responsible for change in chemical and biological properties of both surface and ground water which constitute a health hazard . The heavy metal renders the water unsuitable for a drinking and are also highly toxic . Removal of these naterials is therefore essential . The studies pertaining to the use of inexpensive agro based adsorbent such as tree bark , saw dust , corncob, straw , flyash and fruit shell etc fir heavy metal removal or gaining a lot of importance . In the present study the removal of Fe[II] and Mn[II] has been investigated using Ferronia elephuntum fruit shell substrate through pack column and results are obtained and are quite encouraging. The use of pack column has been investigated at the optimised condition , to study the feasibility of the process for application in small scale industries.
