Effects of pH in the range of 5 to 8 and uranium concentration in the range of 0.02 mg/l to 25 mg/l on the removal of uranium with a strong base anion exchange resin (SBA) and a chelating aminophosphonate resin were studied. The results of the batch and column mode experiments clearly showed that the aminophosphonate resin was an efficient exchanger for the removal of uranium at pH values close to 5 and the SBA resin at higher pH values. In the column experiments, where altogether 2000 bed volumes of drinking water simulant were processed with these exchangers, the uptake of uranium was as high as 99.8% by the aminophosphonate resin at pH 5 and 99.7% by the SBA resin at pH 8.

A new type of anion exchange resin was prepared from cassava stalk (CS) after reaction with epichlorohydrin and dimethylamine in the presence of pyridine and N,N-dimethylformamide. In order to obtain the optimal conditions for the preparation of cassava stalk anion exchanger (CS-AE), the single influential factor experiments were carried out, with nitrate removal efficiency as indicator. Factors like dosage of CS and catalyst, experimental temperatures were examined. The results indicated that the optimal synthesis reaction parameters of dosages were CS: pyridine: dimethylamine = 2 g: 30 ml: 35 ml. The optimal experimental temperature was 100 °C; the catalytic temperature was a key factor in the preparation of CS-AE.
