Study on Binding of Ferrous Ions by Methi Stem

Abstract

The presence of heavy metals such as Cu²⁺, Pb²⁺, Cd²⁺, Hg²⁺
and Fe²⁺ in waste water has been a matter of considerable concern
in recent years because of their toxic properties. There are various
methods such as precipitation, adsorption, ion exchange, etc. available
to remove them from the effluent but all these methods are
comparatively expensive. These heavy metals can be removed by
using cheap agricultural waste products. In this communication use
of stem of Fenugreek Methi ( Trigonella foenum graecum) for binding
of Fe²⁺ ions has been investigated. The effect of pH, temperature
and contact time has been thoroughly studied.
