This article deals with a new method of analysing in seawater, i. e. the uranium is concentrated with an aqueous suspension of basic zinc carbonate, subsequently isolated and determined by extraction-photometric method. In concentrating uranium such factors as stirring time, amount of adsorbent used, acidity of seawater were studied and conditions suitable for analysis were found. This method is simple, accurate and good in reproducibility. It is not necessary to adjust the pH of seawater before analysis. This technique can also be applied to determination of uranium in river or lake. 相似文献
