Does anyone know about cadmium fixation in calcareous soils?

As we know, there is no stable bound state for pp(proton-proton) and nn(neutron-neutron). okay, Why?

the negative scattering length for diproton or dineutron shows that the two proton or two neutron do not form a stable bound state. in addition because nucleons have spin 1/2, the wave function...

Did You try with zeolites (klinoptylolit)?

Banafshe Afrasiabi

thank you but zeolites is not a suitable and perfect material for fixation in calcareous soil, Do you know another one?

You can have a look on Victor Cucarella and Gunno Renman "Phosphorus Sorption Capacity of Filter Materials Used for On-site Wastewater Treatment Determined in Batch Experiments–A Comparative Study" doi:10.2134/jeq2008.0192. It is abou P sorbents, but maybe some materials can be used for Cd sorption.

I know that charred carbon can be used as sorbent too.

In calcareous soils heavy metals are strong bind. So some calcareous rocks (opoka) can be used as sorbent (of P).

Thank you so much for helping me, I will study more about your suggestion :)

Mohammed Hashem Stietiya

You might want to try iron oxides such as ferrihydrite or goethite. In one of my publications we did try but the high calcium carbonate content seemed to overhwhelm the system. If your soils are not highly calcareous, I do advise that.

Thank you for answer, but it is a calcareous one and i . Do you have any idea about biochar?

Cadmium is a heavy metal, the solubility of which is low in a calcareous soil whose pH does not exceed 8.5 but is alkaline in reaction. As such Cd fixation is negligible in calcareous soils.

Dr. Martin i want to know what materials we can use to fix Cd in calcareous soil.

Mr. Mousavi Do you have any paper about it? ( for calcareous?)

Thank you Mr. Reddy for your help. you said that fixation in calcareous soils is negligible but what is your suggestion for reduce Cd in that kind of soil?
