The phrase "a larger affinity for" is correct and usable in written English.
It can be used when discussing a stronger preference or attraction towards something compared to another.
Example: "The study revealed that participants had a larger affinity for organic foods over processed ones."
Alternatives: "a greater preference for" or "a stronger inclination towards".
The modified surface showed a large affinity for selective accumulation of Zr(IV) from acidic solution.
He et al. (2008) prepared an activated nylon-based membrane modified by chitosan and examined its adsorption behavior for Cu2+ ions, the result revealed that its adsorption capacity for Cu2+ ions could arrive at 10.794 mg/g; demonstrating a large affinity for metal Cu2+ ions.
In spite of a large affinity for the hERG-channel, it was observed to cause only moderate QT prolongation.
Thus, NOTT-202a has a large affinity for CO2 and has the potential for its trapping from gas mixtures, as other gases do not show this type of behavior.
It is found that hydrogen interacts more strongly with hydride non-forming elements, B, (e.g. Ni, Mn, Fe) than hydride forming elements, A, (e.g. La, Zr, Ti, Mg) in every hydrogen storage compound, despite that there is a larger affinity of A element for hydrogen than B element in the binary metal-hydrogen system.
It is found that hydrogen interacts more strongly with hydride non-forming elements, B, (e.g., Ni, Mn, Fe) than hydride forming elements, A, (e.g., La, Zr, Ti, Mg) in every hydrogen storage alloy, despite that there is a larger affinity of A element for hydrogen than B element in the binary metal-hydrogen system.
But it has a much larger affinity for 5-HT3 receptors, which have been associated with alcohol consumption.
The efficient photocatalytic degradation of 2-propanol diluted in water on Ti-Beta(F) zeolite and TiO2/HMS(F) mesoporous silica can be attributed to the larger affinity for the adsorption of propanol molecules on the titanium oxide species depending on the hydrophobic surface properties of these photocatalysts.
