磷禽量是石油化工产品的重要质量指标之一。以前用经典的重量法测定,手续繁杂、费时。本文采用氧化锌作捕获剂的比色测磷法,一次平行测定只需约一小时,比国内外的标准方法和其它方法都要简便、快速,磷的相对检出率可达99%以上,并且不受样品中硫、硼、氯、氮、钙、钡、锌、镁、铅等元素的干扰。因此在石油化工产品的生产与研究中都能广泛适用。
Phosphorus is one of the important quality indicators of petrochemical products. Before using the classic gravimetric method, procedures complicated, time-consuming. In this paper, zinc oxide as a capture reagent colorimetric phosphorus method, a parallel determination of just about an hour than the standard methods at home and abroad and other methods should be simple and fast, the relative detection rate of phosphorus up to 99% And from the sample of sulfur, boron, chlorine, nitrogen, calcium, barium, zinc, magnesium, lead and other elements of the interference. Therefore, petrochemical products in the production and research can be widely applied.
