To simulate submerged aging, biodegradable poly (butylene adipate-co-terephthalate) (PBAT) and nondegradable polystyrene (PS) are exposed to ultraviolet A irradiation and river water for 30 days. Aged PBAT shows significant surface oxidation, including a 16% decrease in carbonyl index, a reversal of ζ-potential from slightly positive to -50 mV, and an increase in tetracycline (TC) sorption kinetics.
