本法基于四价钛与二安替比林甲烷互相作用生成黄色络合物,此络合物在波长390纳米处有最大吸收峰,可用分光光度法测定。本文主要研究钛与二安管比林甲烷形成络合物的各项条件和影响因素。试验结果表明,1％二安替比林甲烷用量为20毫升,抗坏血酸用量为5毫升,显色温度为15～30℃,室温下显色20分钟,吸光度趋于稳定,并能保持数小时,在此
This method is based on the interaction of tetravalent titanium and diamtepirin methane to form a yellow complex. The complex has a maximum absorption at a wavelength of 390 nm and can be measured spectrophotometrically. In this paper, the conditions and influencing factors of the formation of complexes of titanium with dipyridamole were studied. The test results show that the amount of 1% diamipinine methane is 20 ml, the amount of ascorbic acid is 5 ml, the color temperature is 15-30 ° C, the color is developed at room temperature for 20 minutes, the absorbency tends to be stable, and can stay for several hours, here
