$plan.v some valuable info about ZeoliteZeolites can also be used as a medium of the active substances i.e. pesticides, herbicides, fungicides or pesticides. Their addition increases plant production levels and biological activity of the soil. Also, zeolite’s excellent sorption properties can be used for the remediation of soils contaminated with heavy metals.
The porous structure of the zeolite crystals allows the selective penetration of particles of a certain size, dehydration and hydration of the crystals, the exchange of water to other molecules and the exchange of ions to different ones (while maintaining the condition of electroneutrality)
Moreover, zeolites are capable to exchange ions with external medium, which is the most significant characteristic of zeolite. “this show how it trap heavy metal from plant such as lead”
Another advantage of zeolites is their ability to hydrate and rehydrate which may have a significant impact on maintaining proper water balance in the soil and prevent drying of soils and soil-like substrates. Due to high porosity, zeolite can store large amounts of water.
Until now some studies have demonstrated advantages of zeolite for the remediation of heavy
metal-polluted soils. The use of zeolites significantly reduced the uptake of cadmium and lead by wheat. Studies concerning the effects of various additives on a change of the solubility of lead,
cadmium and zinc have shown that zeolites significantly reduced the solubility of lead and cadmium in polluted soils
