This invention discloses a method for preparing potassium perborate from sodium perborate mother liquor using modified potassium-form resin, belonging to the field of resource comprehensive utilization technology. The method includes: pretreating a 732 type strong acid cation exchange resin to convert it to the potassium form, then modifying it with a 15-crown ether-5 ethanol solution to obtain a crown ether-modified potassium-form resin; passing the sodium perborate mother liquor through an exchange column packed with this resin, and performing ion exchange at 20-30℃, utilizing the specific selectivity of the crown ether for sodium ions to efficiently replace Na ions in the mother liquor with K ions in the resin, obtaining a pure potassium perborate solution; cooling the solution at -5~5℃ for crystallization, separation, and drying to obtain a high-purity potassium perborate product. This invention directly utilizes waste mother liquor as raw material, with a mild process, and produces a product with high active oxygen content (>16%), uniform particles, and good stability. It solves the problems of high cost, heavy pollution, and poor product quality associated with traditional processes, achieving green and high-value utilization of waste resources.
