西北有色金属研究院王彦君工程师研究了在0.7mol/L HAc-0.7mol/L NaAc-0.002％铜试剂-2.5％EDTA-草酸铵底液中,铀在-0.35～-0.48V产生的吸附催化波,铀含量在0.1—1.0μg/5ml范围内与峰电流成正比。锆及锆合金中大部分共存元素及5mg锆不干扰测定。但Ti、Cu、Mo、Fe、Sn等严重干扰。在3—4mol/L HNO_3介质中,用TBP-甲苯萃取铀可与锆及大部分共存元素分离,然后用水反萃铀,用催化
Northwest Institute of Nonferrous Metal Research Wang Yanjun engineers studied in the 0.7mol / L HAc-0.7mol / L NaAc-0.002% copper reagent -2.5% EDTA-ammonium oxalate in the bottom liquid, uranium adsorption catalyst in the -0.35 ~ -0.48V catalytic wave , Uranium content in the range of 0.1-1.0μg / 5ml is proportional to the peak current. Most of the zirconium and zirconium alloy co-existing elements and 5mg zirconium do not interfere with the determination. However, Ti, Cu, Mo, Fe, Sn and other serious interference. In 3-4 mol / L HNO 3 media, extraction of uranium from TBP-toluene can be separated from zirconium and most of the co-existing elements, followed by stripping of uranium with water,
