仅我们所知,有关蒽醌二磺酸钠(简称ADA)脱硫液中酒石酸钾钠的测定,国内尚无一个比较好的控制分析方法。75年在南京全国合成氨原料净化会议,提出了要建立一个酒石酸钾钠含量的测定方法。我们承担的这个任务,并与衢州化工厂、太原化肥厂和安阳化肥厂等单位共同协作,进行了这方面的工作。 有关ADA脱硫液中酒石酸钾钠的测定,国内均采用钒酸盐比色法。该方法灵敏度低,对含量低于1克/升酒石酸盐的脱硫液吸光度小,测定有困难。采用增量法,就是在加钒试剂之前,向样品溶液中加入巳知量酒石酸盐,回收值很差。我们取衢州化工厂ADA脱硫液进行试验,用增量法测得结果如下:
To the best of our knowledge, the determination of potassium sodium tartrate in the desulfurization solution of anthraquinone disulfonate (abbreviated as ADA) does not have a comparatively good control analysis method in China. 75 years in Nanjing National Ammonia Raw Material Purification Conference, proposed to establish a potassium tartrate sodium content determination. We undertake this task, and with the Quzhou Chemical Plant, Taiyuan Fertilizer Plant and Anyang Fertilizer Factory and other units work together to carry out this work. ADA desulfurization solution potassium sodium tartrate determination, the domestic use of vanadate colorimetry. The method has low sensitivity, and the absorbance of the desulfurization solution containing less than 1 g / l tartrate is small, and the determination is difficult. Incremental method is adding known amount of tartrate to the sample solution before adding the vanadium reagent, and the recovery value is very poor. We take Quzhou chemical plant ADA desulfurization solution for testing, measured by incremental method the results are as follows:
