The standard methods that apply to analytical chemistry still applies with radiochemical analytes. When the behavior of a radionuclide has to be taken into consideration

The standard methods that apply to analytical chemistry still applies with radiochemical analytes. When the behavior of a radionuclide has to be taken into consideration such details are taken care of: The common methods available for separation are: (i) Complexation (ii) solvent (iii) Tracer adsorption.
Adsorption becomes very vital because the samples are recovered from radioactive matrix. Adsorption utilizes special equations called Langmuir adsorption isotherms which follows the equation.
x=xmbCe1+bCe, eqn 1.
Where x,=xm, the amount of solute adsorbed x per unit mass of adsorbent m.
Ce= Equilibrium constant of solute
xm= Amount of solute adsorbed per unit mass adsorbate required for mono layer of layer capacity.
b ,= a constant related to heat capacity of adsorption of material =Q[bexp(-HRT)]
When the eqn 1 is rearranged, it becomes:
Cex=1bxm+Cexm, eqn 2.
Which can further be rearranged as:
1x=1xm+1Ce(1bxm), eqn 3
Using equation 3, a linear plot of 1x against 1Ce is formed. The slope for this linear plot is 1bxm and y intercept as 1xm
The adsorption of one radioactive substance absorption behavior was evaluated and its data was as show below in table below.
