铀除了用于军事目的外,它还是一种人工可控制的巨大核能源。因此,人们对轴在分离与制备等方面的研究一直很重视。例如,用化学法研究铀同位素的分离方法时,要求快速准确地测出铀溶液中的游离H_2SO_4浓度。但是由于铀的水解作用,不能用酸碱滴定法准确地测定出酸的浓度,加之溶液的酸度范围又不适合酸度计测定,那么寻求准确快速的测定方法就显得非常必要。
In addition to military purposes, uranium is a formidable nuclear power that is artificially controlled. Therefore, people have always attached great importance to the research on the separation and preparation of the shaft. For example, the use of chemical methods for the uranium isotope separation method requires rapid and accurate determination of the free H 2 SO 4 concentration in the uranium solution. However, due to the hydrolysis of uranium, acid-base titration can not accurately determine the acid concentration, coupled with the acidity range of the solution is not suitable for acidity meter, then the determination of accurate and rapid determination of the method is very necessary.
