I'll be glueing a piece of acrylic tube OD 25mm in to a PVC fitting bore
size about 25.5mm.
It will all be held fairly ridgidly - neither part is a 'moving part'.
Should I key the surfaces lightly with emery paper prior to bonding or is
there any other method I should use?
Would suggest a wipe with isopropyl alcohol followed by mild abrasion as you
mention. Wipe again with the alcohol to removed abraded material.
I would suggest a two part room temperature cure medium viscosity epoxy
adhesive. Apply a circumferential bead to the end of the tube and assemble
with a twist to spread the adhesive into a uniform film.

Suitability for you would depend on light transmission of the parts
and how many you are doing. Check www.dymax.com if you would like to
pursue this option.
Light curing adhesives are commonly used to bond polycarbonate hubs to
various tubing types in the medical device industry.
The simplest and most common (IV tube sets) method I'm aware of for
bonding acrylic to PVC is solvent bonding with cyclohexanone.
