成功合成了一种新型单宁酸型有机复合吸附剂（PA316TAS），该吸附剂由水解磺化单宁酸（TAS）和多孔型强碱性阴离子交换树脂（PA316）组成，可同时去除海水中多种放射性核素，并研究了其对Mn、Co、Sr、等对PA316TAS吸附剂在不同温度（温度= 278-333 K）和pH值（终pH = 1.6-5.9）范围内的几种海水中进行了研究。结果表明，PA316TAS吸附剂可以选择性地同时去除污染海水中的这些金属离子。
Novel tannic acid-type organic composite adsorbent (PA316TAS), combined with hydrolyzed and sulfonated tannic acid (TAS) and porous-type strongly basic anion exchange resin (PA316) for simultaneous removal of various types of radionuclides in seawater was synthesized successfully and the adsorption behavior of twelve kinds of radionuclides such as Mn, Co, Sr, etc. on the PA316TAS adsorbents has been studied in several types of seawater in the wide temperature (Temp. = 278–333 K) and pH ranges (final pH = 1.6–5.9). We have concluded that the PA316TAS adsorbent can selectively and simultaneously remove these metal ions from contaminated seawater.
