A couple of people mentioned the air admittance valve. It is on a stub on the sewer side of the the sink trap. It unscrews - usually by hand. If the flap in the valve fails to seal it will allow tank odor to escape under the sink. Replacements can be found in most hardware stores.
No amount or kind of tank chemicals will solve the problem.
