Clay colloids
WebIons that are held very lightly with the colloid may be traped between layers of clay micelle. They do not pass to the soil solution very easily. They are called non exchangeable cations. When any cation is added to the soil such as Ca++, K+ or NH 4 through fertilizers and soil amendments they are exchanged with those ions held on the colloid. WebBentonite, a layered clay mineral mainly composed of montmorillonite, is one of the promising sorbents to remove dye pollutants from wastewaters because of appropriate textural properties , ... This problem ultimately makes the regeneration of these colloidal particles quite difficult. Additionally, clay minerals have a poor affinity to low ...
