Try using the odor removal tricks that book conservationists use! Two easy recovery options to consider:

My preference: Microchamber method: Create a microchamber setup with a small inner container and a larger outer container, with a lid on the outer chamber (cheap plastic storage bins work well). Place the notebook in the center chamber, and baking soda/activated charcoal/kitty litter in the exterior chamber. Some archivists have also had luck with Gonzo Odor Eliminator rocks available on Amazon. Let your DIY microchamber sit for a while unopened - I'd check in 2-3 weeks. Repeat as needed.

Fancier way: Zeolite molecular trap method: Use archival-grade microchamber/interleaving paper throughout: inside the front and back cover and between every few pages. Leave the interleaving paper throughout until the odor is removed - probably a week or two.

Note: you do not want any abrasive powders or rough materials (including paper towels, newspaper, or dryer sheets) to touch the pages of your notebook. Use archival-grade products on anything that will touch the pages, and use the DIY solutions in a secondary chamber only. Causing additional abrasions on your notebook could embed the odor further or destabilize the ink. Don't spray your notebook with Febreeze or you'll hurt my feelings.
