氯丁生胶中游离硫和四乙基秋兰姆二硫化物(TETD)的分别极谱测定已有报导。但是,当硫和TETD共存时,将相互干扰,致使两者难于同时测定。因而它们的同时极谱测定法之研究,乃是一个值得探索的课题。 我们考察了在不同底液中流和TETD的极谱行为、测定条件和影响因素,所确定的同时极谱测定法,快速、简便,方法的平均偏差和平均误差均小于±5％,能满足一
The separate polarographic determination of free sulfur and tetraethylthiuram disulfide (TETD) in neoplasms has been reported. However, when sulfur and TETD coexist, they interfere with each other, making it difficult to measure both simultaneously. Therefore, their simultaneous polarographic determination of the study, but it is a topic worth exploring. We investigated the polarographic behavior, determination conditions and influencing factors of flow and TETD in different basal fluid. The simultaneous and polar simultaneous determination method was rapid and simple. The mean and average errors of the method were less than ± 5%
