초록

${\alpha}-HIBA$를 용리제로한 양이온 교환 수지통을 사용하여 철, 코발트, 니켈, 이트륨 및 희토류 원소와 같은 여러가지 금속의 공존이온으로 부터 티탄, 니오브 및 지르코늄을 함께 분리하는 방법을 발전시켰다. 본 연구의 결과 르코늄의 꼬리끌기현상은 용리전에 행한 수산화침전에 기인하고 있음을 알았다. 예를 들면 지르코늄을 수산화나트륨으로 침전시킬때 다른 저자들의 보고와는 달리 지르코늄은 심한 꼬리끌기현상을 나타냄을 알았다. 본 연구에서는 이러한 꼬리끌기현상을 없애고 또한 이 이온들을 함께 분리하기 위한 목적으로 이온교환법을 적용하였다. 본 방법을 사용한 결과 조사된 지르코늄으로부터 생성된 $^{90m}Y$$^{90}Y$을 방사화학적 순도로 분리할 수 있었다.

A method was developed for the separation of titanium, niobium and zirconium together in a group from the coexisting ions of various metals such as iron, cobalt, nickel, yttrium and rare earths by means of the cation exchange column using ${\alpha}$-hydroxyisobutyric acid as the eluent. In the course of the present investigation, it was found that the tailing phenomena of zirconium were attributable to the hydroxide precipitation which was made prior to the elution. For example, if zirconium was precipitated by sodium hydroxide, the tailing of zirconium became very serious in contrast to the results reported by others. This paper describes how these tailing phenomena of zirconium were prevented and how a practical procedure for the separation of these ions was, achieved using ion-exchange method. Using the present method the nuclides of $^{90m}Y$ and $^{90}Y$ were separated with radiochemical purity from the irradiated zirconium.
