Moreover, interactions The influence of variables such as adsorption temperature, polar between surfactant and solvent should also be allowed for. chain length, and nature of functional groups on the adsorption, There are some internal factors such as the length and nature from aqueous solutions, of various surfactants (TX-114, TX-100, of the polar chain of the surfactant and nature of the solid TX-165, TX-305, NP1P4E, NP4P1E, NP4S, NP10S, and NP25S) surface that must be taken into account.
