Example text

In general, the lower the affinity of the adsorbent for the solute, the higher will be the adsorption capacity. Adsorbents such as activated carbons and polymeric adsorbents, have high adsorption capacities in water because a low adsorption potential energy is needed on the part of an adsorbate to displace water from the surface of these adsorbents. The affinity of the solute for the surface must also be larger than the affinity of the solute for the solvent in order for adsorption to be highly favoured.

The adsorbate molecules arrange 36 ECONOMIC REMOVAL OF METALS FROM AQUEOUS SOLUTIONS themselves on the surface with unlike charges nearest to each other, resulting in an electrostatic attraction which can be much stronger than the van der Walls attraction. If the adsorbate molecules do not have a permanent dipole, they can acquire an induced dipole when placed in an electrostatic field near an ionic solid surface. Unlike van der Waals forces, the electrostatic forces can be repulsive as well as attractive.

NSW-133) Research centrifuge REMI (R 24) (Continued) MATERIAL AND METHODS 41 (Continued) Instrument Model No. 1 Adsorption Experiments After development of the two nano-adsorbents, effects of various important parameters on the removal of selected metallic species by nano-adsorbents were studied. For the removal of selected metallic species, batch adsorption experiments were conducted. All the chemicals used in the present studies were of AR grade and were procured from Merck, Mumbai, India. The chemicals used in this study were ammonia solution, nickel sulphate, dimethylglyoxime, bromine water, hydrochloric acid, 95% ethyl alcohol, potassium dichromate, 1,5-diphenylcarbazide, sulphuric acid, phosphoric acid, nitric acid, sodium hydroxide, and sodium perchlorate.
