研究含锑药物治疗某些感染性疾病(例如血吸虫病)时,需要测定生物材料中微小锑量。早年 Maren 用硫酸与硝酸混合液消化生物样品,再用蓝光碱性蕊香红(Rhodamine B,以下简称蕊香红乙)显色,制订了一种微量锑的比色测定法。由于该法具有缺点,历年来许多学者另创新法将其改进。但是所有的新方法主要是在显色方面的改进,对于时间宂长而难于掌握的消化过程,基本土仍与旧法相同。我们利 When studying antimony-containing drugs for the treatment of certain infectious diseases (such as schistosomiasis), it is necessary to determine the amount of trace antimony in biological materials. In the early years, Maren digested biological samples with a mixture of sulfuric acid and nitric acid and developed a colorimetric assay of trace antimony with a color developed by Rhodamine B (hereinafter referred to as Ruixiang B). Due to the shortcomings of the law, many scholars over the years another innovation law to improve it. However, all the new methods are mainly improvements in color rendering. For the long and difficult digest process, the basic soil is still the same as the old one. We benefit
