  • FF lab report: PRACTICAL 3: ADSORPTION FROM

    2013-5-28 · Adsorption is a process where free moving molecules of a gaseous or solutes of a solution come close and attach themselves onto the surface of the solid. The attachment or adsorption bonds can be strong or weak, depending on the nature of forces between adsorbent (solid surface) and adsorbate (gas or dissolved solutes).
