研究了用福建南平武夷山废红茶粉末从水溶液中吸附 UO2＋2，考察溶液pH、离子强度等对铀的静态吸附的影响，采用固定床探讨初始铀质量浓度、溶液流速、废红茶用量对铀的动态吸附的影响。根据动力学模型、吸附等温模型拟合曲线以及吸附前后废红茶的FT-IR图谱推断吸附机制。
研究瞭用福建南平武夷山廢紅茶粉末從水溶液中吸附 UO2＋2，攷察溶液pH、離子彊度等對鈾的靜態吸附的影響，採用固定床探討初始鈾質量濃度、溶液流速、廢紅茶用量對鈾的動態吸附的影響。根據動力學模型、吸附等溫模型擬閤麯線以及吸附前後廢紅茶的FT-IR圖譜推斷吸附機製。

Powdery adsorbent was prepared using the scrap of black tea produced in Wuyi Mountain Fujian China .Then ,the adsorption properties of uranyl ion on this adsorbent were studied ,the influence of pH ,ionic strength and other factors on adsorption were discussed .The adsorption mechanism was inferred by fitting experimental results with dynamic model and adsorption isotherm model ,and the FT-IR characterization of the adsorbent before and after adsorption was analyzed . Finally ,the effect of concentration of uranyl ion ,flow rate of solution and dosage of adsorbent on dynamic adsorption was tested by fixed bed .
