leaching and adsorption

  • Absorption vs Adsorption Difference and Comparison

    Adsorption is the process in which atoms, ions or molecules from a substance (it could be gas, liquid or dissolved solid) adhere to a surface of the adsorbent. Adsorption is a surfacebased process where a film of adsorbate is created on the surface while absorption involves the entire volume of the absorbing substance.
