A purification method for detection of a strontium isotope in a silk cultural relic. The method includes: (1) enrichment of the strontium isotope: after cleaning the silk cultural relic, adding the silk cultural relic to a digestion agent for microwave digestion, and conducting evaporation drying; and adding a dried product to a nitric acid solution for centrifugal separation, and extracting a supernatant; and (2) purification of the strontium isotope: first, mixing 4',4″(5″)-di-tert-butyldicyclohexano-18-crown-6 and a defoamer and adsorbed to a purified resin separation column, and pre-cleaning the purified resin separation column with a nitric acid solution; next, injecting the supernatant in step (1) into the purified resin separation column with a nitric acid solution as a carrier solution; and then, injecting anSr solution and an elution solution into the purified resin separation column in sequence to obtain a separated and purified strontium solution.
