I need to find out the normalized selectivity which is a function of an additive's mass fraction in the polymer. How can i plot it?
Not specified, fully question. What do you understand by the term "normalized selectivity". Do you mean it, that its value changed from 0 to 1 ?. What do you mean by selectivity. I'm guessing that the polymer to be used in the process of adsorption, as a membrane or in a chemical process. You have to specify! Particularly in the case of chemical reactions, the definition is different from the others. Charts space for two additives is the norm. Worse three, but you can perform cross-sections.
Sir
Thank you so much for putting an effort to reply my question, i am oblige.
I have synthesized a polymeric membrane and then got its selectivity values for CO2/CH4 and CO2/N2, for a range of pressure values, now my concern is how can i derive normalized selectivity value from this??
Sir please let me know what can be done regarding my concern.

It seems that I can not help you. I do not know how to define normalized selectivity based on the selectivity of the membrane I guess as
aij=(cPi/ cPj)/ (cIi/ cIj), where c – mass fraction, molar fraction or partial pressure, P – permeate, I – inlet.
for different trans-membrane pressure drops.
Sir
Thank you so much for again putting an effort to clear my doubt, i am oblige.
