| 摘 要： | 研究了苯乙烯生产有机废水总有机碳(TOC)与化学需氧量(COD)的相关性。用日本岛津公司TOC-VCPH总有机碳分析仪测定了苯乙烯生产有机废水的TOC,同时用标准重铬酸钾法测定COD,建立了COD与TOC之间回归方程,表明了它们之间有很好的相关性。并对其进行精密度和准确度分析,为该水体中有机物的TOC监测代替COD监测提供了实践依据。

| Abstract: | The relativity of total organic carbon （TOC） and the chemical oxygen demand （COD） of organic wastewater from styrene production has been researched.TOC of organic wastewater styrene production has been tested by Shimadzu Corporation＇s TOC-VCPH.At the same time,COD has been tested by the standard potassium dichromate method.Regression equation between COD and TOC has been established.All show that there is good correlation between COD and TOC.Precision and accuracy analysis of the regression equation has been carried out.This is provided a practical basis for the replacement of COD monitoring by TOC monitoring of organic waste. |
