Appraisal of Mixed Amorphous Manganese Oxide/Titanium Oxide Sorbents for the Removal of Strontium-90 from Solutions, with Special Reference to Savannah River Site and Chernobyl Rad...
Published 2006-12-01“…Sorption isotherms were used to establish the efficiency of the templating process, while the proton-exchange capacity of AMTO was determined to show that the solids were really protonated. Use of the 90 Sr isotope showed that there was little dependence of the distribution coefficients for AMTO on pH, and at pH < 7, i.e., in neutral and acidic media, AMTO had a much greater affinity for strontium than commercial sorbents. …”

Research Progress on Carbon in River Waters
Published 2020-01-01“…Due to the different climatic conditions and flowing regions,carbon content,source and flux in rivers are obviously different.The identification methods of river carbon sources mainly include C/N ratio,carbon isotope,fluorescence spectrometry and biomarker,which have their own advantages and disadvantages.Therefore,the comprehensive application of multiple methods can improve the accuracy of source apportionment analysis results.River carbon flux is estimated by the product of river concentration and runoff,which is improved based on local river characteristics by later researcher.In the process of transport from land to sea,river carbon will also be released into the atmosphere in the form of CO<sub>2</sub>.Therefore,understanding the distribution of river p<sub>CO<sub>2</sub></sub> is of great significance for the study of biogeochemical cycle of river carbon.…”
