一、引言用不分离铀的间接极谱法测定铀中含量小于1%的硫酸根时,由于大量铀的存在,严重地干扰铅的测定,因而会影响硫酸根的测量准确度。测定硫酸根的方法很多,但我们认为极谱法仍然是一种较好的方法,因为即使没有完全分离出铀,也不会干扰硫酸根的测定。曾看到一些分离铀与硫酸根的文献。虽然铀(Ⅵ)与硫 I. INTRODUCTION In the indirect determination of sulfate with less than 1% of uranium by indirect polarography without separating uranium, the measurement of sulfate is seriously affected by the presence of a large amount of uranium, which will affect the measurement accuracy of sulfate. There are many ways to determine sulfate, but we believe that polarography is still a better method because it does not interfere with the determination of sulfate even if uranium is not completely separated. Have seen some separation of uranium and sulfate literature. Although uranium (Ⅵ) and sulfur
