摘要

A rapid radiochemical separation method was developed for the assessment of uranium in urine using indigenously synthesised amidoximated crosslinked polyacrylonitrile (ACPAN) adsorbent. The synthesised adsorbent exhibited a high uranium adsorption capacity for urine samples conditioned at pH 2. The reusability of the ACPAN adsorbent was demonstrated by its stable adsorption capacity for ultra-trace levels of uranium over multiple cycles. The standardized method complied ANSI 13.30 radio bioassay performance criteria, validating the suitability of this novel technique for precise determination of uranium in urine. The method developed is rapid, sensitive, and can be applied for emergency bioassay of uranium in urine.
