This work aims to establish the current contents and geochemical pattern of uranium and rare earth elements in the soil of Ras Tanura, Saudi Arabia. The instrument utilized was the ICPE-9820 Shimadzu Japan, which employs inductively coupled plasma optical emission spectrometry (ICP-OES) to measure eight REEs (Eu, Hf, La, Lu, Sm, Tb, Yb, and Ce) and uranium. The values of uranium concentrations ranged from 0.07 to 5.72 mg/kg with an average of 3.30 mg/kg. The concentrations of rare earth elements (mg/kg) varied from 6.35 to 0.25 for Eu, 21.2–0.53 for La, 1.74–0.11 for Lu, 5.14–0.20 for Sm, 13.6–0.64 for Tb, 6.42–0.07 for Yb and 13.4–0.87 for Ce. The contents of REEs were in the following arrangement: La > Tb > Ce > Eu > Yb > Sm. The Eu/Sm and La/Lu ratio values ranged from 1.17 to 1.52 and 0.56 to 1.24, respectively. The measured data were compared with similar studies worldwide. This study provides valuable insights into the current status of uranium and rare earth element concentrations in the soil of Ras Tanura, Saudi Arabia.

In this study, we used the hydrothermal method to synthesize carbon-coated magnetic Fe3O4 nanoparticles and then modified by sodium hydroxide to yield magnetic carbon nanomaterials (Fe3O4@HTC-NaOH). The microstructure and chemistry of the material were characterized by TEM and FTIR. We investigated the adsorption behavior of materials for uranium (VI) under different conditions, including pH, contact time, initial uranium concentration, and temperature. The results indicated that this material adsorbs uranium quickly, achieving equilibrium in static adsorption after approximately 225 min. The adsorption behavior was strongly dependent on pH, and the maximum adsorption capacity (457.83 mg/g) was reached at pH 5.5. The initial concentration also had a role in the adsorption behavior. With the gradual increase of the initial concentration of uranium (VI), the adsorption capacity showed an increasing trend and reached saturation at 100 mg/g. Adsorption isotherm could be well fitted by the Langmuir model and the pseudo-second-order kinetic model. And the results indicated it is a heat-absorbing reaction. Owing to the introduction of Fe3O4, the material is magnetic and the solid-liquid separation can be rapidly completed by the pairing of magnets. The new material could be regenerated using HNO3, and the adsorption rate could maintain above 75% after five adsorption/regeneration cycles, which illustrated its certain practical application value.</div>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":"333 12","pages":"6213 - 6224"},"PeriodicalIF":1.5,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142778347","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}
