依據蘇聯藥典氫氧化鈉溶液滴定方法测定磺胺噻唑含量,速度较用亞硝酸钠法为快;樣品数量少時,快慢尚不甚顯,但如遇樣品多時,可先將樣品分别溶解,再逐一滴定,則本方法遠較迅速,並且用本方法可以避免用水,而丙酮則容易得到。用過的丙酮,尚可收回應用,更較節省,故此法值得介紹。 Determination Sulfathiazole sodium hydroxide solution according to the USSR Pharmacopeia titration method using sodium nitrite faster than faster method; number of samples is small, the speed is not very significant, but in case of long sample, the sample may be first separately dissolved, then one by titration, the method of the present far more quickly and to avoid the process water, and acetone, can be easily obtained. Spent acetone, can still recover the application, more saving, so this method is worth introducing.
