A Critical Review on the Determination of Aluminum Metal

Abstract

필자는 1970년 이전의 약 20년간에 보고 되었던 알미늄 금속의 분석법에 관한 논문들을 다시 검토해 보았다. 1970년대 이전에 발표된 문헌들로 미루어 보아 그 당시에는 미량 성분의 알미늄 금속 분석에 판한 연구가 그다지 활발하지 못했다 하겠다. 그러나 필자가 조사한 기간에는 미량 성분의 분석에 관한 연구가 괄목할 만큼 두드러지게 나타났으며 용량 분석방법이 특히 많이 쓰였음을 엿볼 수 있었다. 기타 중량법과 흡광 분광 광도법, 분광 헝광 분석법, 발광 분광 광도법, 방사화 분석법 등등의 기기분석 방법이 공업적으로 점차 많이 쓰였음을 알 수 있었다.

분석 방법은 금속의 정제적인 이용도가 개밭됨에 따라 실지로 현저하게 발전되었음을 보고된 문헌을 통하여 알 수 있다. 요즈음에는 핵화학에 관한 기술이 고 순도 물짙이나 합금들에 들어 있는 극미량의 알미늄을 정확하게 정량하는 극히 좋은 수단이 되고 있는것 같다.

지난 20년간에 좋은 방사 화화적인 분석법과 분리 방법이 급증하였지만 우리 나라 공업계에서는 아직도 이에 관한 새로운 기술의 결핍으로 공정의 제품 관리에 사용되고 있지 않다.

The analytical methods of aluminum metal are reviewed for about 2 decades up to 1970.

Prior to the past two decades few accurate quantitative methods were recorded for the determination of micro amount of aluminum.

Volutmetric methods were widely used particularly for this aluminum metal. Colorimetric, spectrofluorometric, X-ray fluorescence, spectrographic, and gravimetric methods are also applied in industrial purposes. Generally it is a fact that coincident with a improvement in the economic status of a metal, there is a corresponding impetus in the development of methods for its analytical determination. Along with the great improvement in the economics of the aluminum metals and its alloys are found a really significant advance in the recorded analytical methods for aluminum in various matrices. Recently the nuclear chemical techniques may be considered very powerful tools for an accurate determination of submicrogram amount of aluminum in high purity materials or in alloys. The past two decades have seen a rapid increase in the number of effective analytical methods of separation and determination.

Despite of the accumulation of the data, it seems to be very hard to manage for their routine work in an industry because of their lackness of new knowledge of nuclear and radiochemistry in the developing country like Korea.
