The results showed that the uranium removal ratio reached 98.34% at 228 h, and the stability of the immobilization product was also enhanced with prolonged reaction time. The remediation of uranium-contaminated wastewater involved two stages. In the early stage, soluble U(VI) was removed swiftly and mainly absorbed onto cell surfaces through electrostatic interactions and complexation. In the second stage, U(VI)-phosphate minerals appeared in various forms, including metaankoleite [K(UO2)(PO4)·3H2O], chernikovite [H2(UO2)2(PO4)2·8H2O], and metanatroautunite [Na(UO2)(PO4)·3H2O]. The crystallinity of U(VI)-phosphate minerals improved with increasing reaction time. Meanwhile, U(IV) was also detected as UO2 in the crystalline state. Uranium precipitates were found inside cells at this stage, and these precipitates were dominated by metaankoleite. In the whole system, unclassified_f_Enterobacteriaceae played a major role, and Lysinibacillus, Dysgonomonas, Methylobacterium–Methylorubrum, Devosia, Petrimonas, Citrobacter, Microbacterium, and Paenibacillus also participated in the remediation process.

The measured nuclear well logging parameters, which are natural gamma ray (GR), the density (σ), and neutron porosity (Ф%) allow the computation of the corresponding of clay content (CC%), heat production (HP), and radioactive content (Y) parameters for different lithological basalts of four drilled boreholes of (Jaba, Jabeit, Kodana, and Al-Asbah), located along N-S profile. Different population ranges of GR, CC, HP, σ, Y and Ф have been isolated in the study region by applying advanced statistical multi-fractal concentration-number (C-N) approach. The vertical and lateral variations of the measured and computed logging parameters have been well determined by analyzing a 2D profile of 32 km long passing by the four studied boreholes. The main finding of this paper is the integration of the different distinguished basaltic ranges of those nuclear well logging parameters for the identification of four lithological basalts in the study region; hard massive basalt, massive basalt, pyroclastic basalt, and alteration product basalt and clay. The nuclear well logging methods applied in this paper demonstrate their efficacy, and can be therefore easily practiced to characterize similar basaltic environments worldwide.</div>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":"334 8","pages":"5335 - 5348"},"PeriodicalIF":1.6,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145090582","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}
