The development of novel MOFs for radiation detection and luminescence-based dosimetry is the latest topic of interest. In this contribution, we have synthesized and characterized a Uranyl MOF, which shows an optically stimulated luminescence (OSL) phenomenon induced by ionizing radiation. OSL dosimetric studies were carried out on Uranyl MOF, which revealed that MOF has a linear dose–response up to 100 Gy with a 1.1 Gy minimum detection dose. It also shows good reusability, around 30% fading in one day, very low fading beyond one day to 30 days, and decent radiation stability (stable up to 10 kGy). Preliminary dosimetry results are promising and show that Uranyl MOF can be utilized in the field of low-dose radiation processing applications in the future.</p>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142252934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanofiltration technology and ion exchange technology were combined to treat uranium-containing wastewater and it can achieve the discharge standard. For the treatment system, uranium was firstly enriched in nanofiltration concentrate, and the concentrate entered the ion exchange system for selective adsorption of uranium. Because uranium exists in the form of complex cations or anions at different pH conditions, the use of cation–anion exchange resin tandem treatment technology can effectively and selectively adsorb almost all uranium. Both laboratory and engineering application results showed that the uranium concentration in the nanofiltration solution can be reduced to less than 50 μg/L after treating by the nanofiltration system for the wastewater containing 5–100 mg/L uranium.
