I need references to an experiment to do it in our lab in this way, used the same method, there is a reference that did the same research, but on water not soil.

Steps to carry out the experiments:
Soil preparation (references for quantities and other proportions and on what basis).
contamination preparation using (references for quantities and other proportions and on what basis).

For the first time, cesium
For the second time, Sr strontium
For the third time, U uranium
Mixing the soil and the material together with increasing and decreasing of the amount in each experiment to compare the difference with specific grams:

PPM calculation of mixture.
KD calculation for mixture.
ICP calculation of the mixture.

Adding Bentonite as a processor and comparing the result of the solution after adding it in different proportions of percentage.

Adding Sodium Silicate as a processor and compare the result of the solution after adding it in different proportions of percentage.

Calculate the absorption of the soil in all steps.
