  • Absorption vs Adsorption Difference and Comparison Diffen

    ProcessUsesReferencesAdsorption and absorption are both sorption processes. Absorption occurs when atoms pass through or enter a bulky material. During absorption, the molecules are entirely dissolved or diffused in the absorbent to form a solution. Once dissolved, the molecules cannot be separated easily from the absorbent. Adsorption is generally classified into physisorption (weak van der Waals forces) and chemisorption (covalent bonding). It can also be caused by electrostatic attraction. The molecules are hLive Chat

  • The Problem of Leaching Pesticide Environmental Stewardship

    Leaching is the movement of contaminants, such as water soluble pesticides or fertilizers, carried by water downward through permeable soils. Generally speaking, most pesticides adsorb to soil particles (especially clay), become immobile, and do not leach. The fate of mobile pesticides, however, can be thought of as a race between the various degradation processes and leaching to groundwater.
