In this study, column experiments were conducted to investigate the effect of quartz sand particle-size and U(VI) concentration in the U(VI)-HA system. It was found that the migration rate of U(VI) in coarse sand (0.25 ~ 0.5 mm) was faster than that in fine sand (0.075 ~ 0.25 mm) and medium sand (0.5-2 mm) in individual U(VI), because of the smaller specific surface area of coarse sand. With the increase of sand size and the U(VI) concentration, the migration rate of U(VI) increases faster and the maximum outflow ratio (C/C<sub>0</sub>) adds. The migration of HA in quartz sand column was little affected by sand size. HA is a weakly acidic colloid with negative charge, and the surface of quartz sand also carries negative charge. The mutual electrostatic repulsion counteracts the influence degree of sand particle-size. HA (50 mg/L) promotes U(VI) migration in the U(VI)-HA system, while the influence of sand size and the U(VI) concentration on the U(VI) migration is weakened. The main reason are the competitive adsorption between HA and sand surface and the formation of U(VI)-HA complex.</p></div>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":"334 4","pages":"2623 - 2634"},"PeriodicalIF":1.5,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143888768","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}

In this work, we used the deconvolution method, based on the Levenberg–Marquardt algorithm, to determine the contributions constituting the irradiated alanine spectrum. Fourteen contributions were revealed. Analysis of the comportment of these contributions as a function of irradiation dose and post-irradiation storage time revealed quasi-linear evolution according to irradiation dose, and good stability of the produced free radicals during the post-irradiation storage period.
