Jute & Sunnhemp has been used as adsorbate for the adsorption of metal ions. The forces operating between the molecules of an adsorbate and the adsorbent are mostly short range forces as suggested by Langmuir. These forces may be non specific like dispersion forces, orientation forces and induction forces or may be chemical bonds. Adsorption depends on the surface area of the adsorbate, pH, contact time etc. The surface charge of the adsorbate is an important criterion in adsorption. The adsorbing powers of many substances can be increased by temperature treatment. In the present study, the effect of contact time, temperature, pH, etc is reported. The paper also discusses the applicability of Freundlich and Langmuir adsorption isotherms.
