Adsorption and desorption of curium and plutonium were discussed in relation with difference of materials, time dependence and acidity of leachate. Curium, which has been previously leached out from waste glasses, showed a relatively simple adsorption and desorption behavior. In the case of plutonium, the colloidal species would take a large part in the adsorption and desorption processes. The relationship between the ratio of the colloidal to the ionic species of plutonium and the adsorption-desorption behavior was discussed. The observation of alpha autoradiographs elucidated that the ionic adsorption was desorbed more easily than the colloidal one.</p></div>","PeriodicalId":100966,"journal":{"name":"Nuclear and Chemical Waste Management","volume":"8 1","pages":"Pages 45-54"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0191-815X(88)90007-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75419525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results from chemical analysis indicated that the greatest concentration of contaminants was present in samples from an oil-stained area, and from the vicinity of a PCB disposal area. The results from the analyses of mutagenicity of these samples indicates that these samples also had the greatest specific activity, inducing 155 and 140 net revertants when the methylene chloride and methanol fractions were assayed, respectively. However, when the samples are compared on the basis of weighted activity, the sample from the vicinity of the PCB disposal area had the maximum activity (2410 revertants per gram of soil). While a second sample from the vicinity of the PCB disposal area had a weighted activity of 757 revertants per gram of soil, it contained no organic constituents which could be identified using standard analytical procedures.
