近年来利用肼,羟胺类还原剂的钼蓝法测磷已有不少报道。但把它直接应用于生产例行分析的文章尚未见报道。我厂在总结文献的基础上,做了大批量生产分析试验,并研究了砷的干扰,总结出了此分析方法。经过二年多生产例行分析证明,此方法应用于生产中普碳钢,铸铁中磷的测定,具有操作简便快速、显色稳定灵敏、结果准确及重现性均好的特点。
In recent years, the use of hydrazine, hydroxylamine reducing agent molybdenum blue method has been reported a lot of phosphorus. However, it has not been reported that it is applied directly to the production of routine analysis. Based on the summary of the literature, our factory made mass production analysis experiments and studied the interference of arsenic, and summed up the analysis method. After more than two years of production routine analysis shows that this method is used in the production of carbon steel, cast iron in the determination of phosphorus, with simple and rapid operation, stable color sensitive, accurate and reproducible results are good characteristics.
