| 摘 要： | 改进的极谱法把三价铁作为底液的一种组分,当钼铀质量比达50时,仍不影响1mg/L铀的测定。对ρ(U)为1~100mg/L的在线测量的采样原理、底液贮存和汞的回收再利用进行了研究。扼要介绍了在线监测的工厂运行情况。

| Abstract: | A fast polarographic method using Fe~(3 ) as a component of the base solution has been deve-loped. Element Mo does not affect the determination of 1 mg/L U when the mass ratio of Mo/U is up to 50. The sampling principle of on-line monitoring uranium concentration (1-100 mg/L), storage of base solution and reuse of mercury are studied. The running result of on-line monitoring in a uranium mill is briefly introduced. |
