I am going to modified the pristine montmorillonite (MMT) by using cationic surfactant.
However I am confusing on the way to calculate the weight of the surfactant.
I have been searching hundred of journals but couldn't get any information on how to calculate it.
For example:
MaterialsThe commercial sodium montmorillonite (Cloisite®Na) used in the present study was supplied by Southern Clay Products, Gonzales, Texas (USA). The cation exchange capacity (CEC) of montmorillonite (MMT) is 92.6 mequiv/100 g as reported by suppliers. The basal spacing of MMT is 12.1 Å. This MMT was used as such without any further purification. Various amines used as cationic surfactant.
Organoclay preparation and characterizationThe required amount of amine (taken as twice the amount required based on CEC of MMT) based on 2.5 g of Cloisite®Na was protonated in 100 ml of 1 N HCl for 1 h at room temperature with vigorous stirring to obtain the ammonium chloride salt.
However, they do not state that how to calculate the required amount of amine based on CEC??
Anyone can help me out in this?
Thank you so much in advance.
