用蓝细菌满江红鱼腥藻为吸附材料，研究了时间、ｐＨ、阳离子、阴离子等对水相中低浓度Ｕ（Ⅵ）的吸附影响。实验结果表明，满江红鱼腥藻对浓度低于５．５ｍｇ／Ｌ铀吸附迅速，平衡时间不超过２ｍｉｎ；富集铀酰离子的最佳ｐＨ范围在５．０—８．５，铀酰离子可能以［ＵＯ２ＯＨ］＋形式与藻细胞结合；Ｌｉ＋、Ｎａ＋、Ｋ＋、ＮＨ４＋不与ＵＯ２＋２竞争；Ｃｕ２＋、Ｃｄ２＋、Ｍｎ２＋、Ｚｎ２＋使满江红鱼腥藻的吸附容量下降；Ｃｌ－、ＳＯ２－４、ＮＯ－３不影响藻细胞对铀的吸附；经过简单串级，３．５‰—４．５‰鲜藻可将模拟废水中的铀从５．５ｍｇ／Ｌ降低至０．０５ｍｇ／Ｌ。
Using cyanobacteria Azolla as the adsorptive material, the effects of time, pH, cation and anion on the adsorption of low concentration U (Ⅵ) in aqueous phase were studied. The results showed that Anabaena variabilis adsorbed uranium at a concentration lower than 5.5mg / L rapidly, and the equilibrium time was no more than 2min. The optimal pH range for enrichment of uranyl ion was 5.0-8.5, uranyl ion might The binding capacity of Cl-, SO2-4 and NO-3 to algae cells in the form of [UO2OH] + was higher than that of UO2 + 2, while that of Li2 +, Na +, K + and NH4 + The adsorption of uranium to algae cells was not affected. After a simple cascade, 3.5 ‰ -4.5 ‰ fresh algae could reduce uranium in simulated wastewater from 5.5 mg / L to 0.05 mg / L.
