Morphology
anion-exchange + resin
The phrase is compositional: anion-exchange describes the function (exchanging anions) and resin names the material, so the overall meaning is directly derivable as a resin that exchanges anions. This follows standard compound-noun formation common in technical vocabulary, so a learner who knows the constituent words would understand the MWE.
Etymology
Anion-exchange resin is made of tiny plastic beads called a resin, and the beads have positive spots that grab anions ('negative ions') and exchange them for other ions. So it literally means a material that swaps negative particles, which is why it is used to remove impurities and clean water.
