摘要
研究用离子色谱法测定工业循环冷却水中总磷量的方法。采用0.074mol/L K_2S_2O_8-0.500mol/L NaOH作为混合氧化剂,确定了最佳实验条件。方法的标准偏差为2.12％。用离子色谱法测定样品的分析结果与光度法进行比对,结果相吻合。方法简便、实用,灵敏度、准确度高。
A method to measure total phosphorus in industrial circulating cooling water by ion chromatography has been developed. 0.074 mol/L K2S2O8 -0.500 mol/L NaOH was used as oxidizer. The optimized measuring condition was determined. The relative standard deviation of this method is 2. 12%. The results between ion chromatoraphy and spectrometry were compared and the results matched very well. The ion chromatography is simple, practical, sensitive and accurate.
