| 摘 要： | 应用有机吸附剂从海水中提取铀,资料上已有若干报道.Davies.R.J,等曾经报道过用甲醛、间苯二酚胂酸缩合的树脂,虽然这种树脂交换容量大(通水112天,1010微克铀/克),选择性好,提取率高,但它在水中缓慢水解,吸附能力下降,溶损也较大(2.3%初量/周),因而没有得到进一步的发展.Bayer,E.提出用聚乙二醛三氨基苯酚和经硅藻土烧结的聚丙烯氧肟酸树脂,从海水中提取铀和铜等金属,但吸附量不很高,树脂的强度也差,因此很快就中断了研究.苏联一些学者也报道了用AH、等阴离子交换树脂提取铀的研究工作.AH-2Φ树脂具有一定的吸附量(30微克铀/克),在海水中比较稳定,但交换容量很低,价格也较贵.

| Abstract: | AHP resin organic adsorbent for extraction of uranium from sea water,which was synthesized in the aqueous phase with tetraethylene pentamine(TEPA), epichlorohydrin(ECH)and C-reagent as the raw material and rubber solvent oil(120 gasoline)as the pore-producing agent is recommended here.The characteristics of the resin are:(1)It has a great exchange capacity;20-40 mesh of wet sample was able to adsorb stably over 900μg U/g-dry resin through which fresh sea water was fassed for 15 days(the average adsorption capacity of five sets of sample was 1163 μg U/g-dry resin,but 1560μg U/g-dry resin was the highest degree of adsoption among the samples);(2)It has a high exchange rate;a gram of the resin was able to absorb about 80μg of uranium every day;(3)it has a good selection and a high extraction rate and is less affected by the temperature of sea water;(4)it is reusable:there was a set of samples which had been used 12 times and the average adsorption capacity was 620μg U/g-dry resin and the loss by solution was about 5.6%;(5)It has a lower mechanical strength and a higher loss on dissolving:the loss by solution in the first period of use was about 20%. This sort of resin has never been reported before. |
