Activated Bleaching Earth

Chemical adsorption is through chemical linkage with a significant selectivity. The decoloration for fats and oils is by adsorbing and removing the pigment, which is in the state of the colloidal particles dispersed in the oil or dissolved in oil.

    Product Description

    The most important properties of activated clay are adsorption and decolorizing ability. Adsorption mainly means physical and chemical adsorption. Physical adsorption is attributed to Van Der Waal's forces. This force is commonly found both on the surface of the adsorbent and among molecules of adsorbate. As a result, the physical adsorption is non-selective but easy to reach equilibrium and has a better adsorption speed. Chemical adsorption is through chemical linkage with a significant selectivity. The decoloration for fats and oils is by adsorbing and removing the pigment, which is in the state of the colloidal particles dispersed in the oil or dissolved in oil.
