摘要
介绍了运用快速消解法测定含高氯废水中COD的研究,通过HgSO4络合法,对含高氯水样辅以稀释法,从而消除氯离子的干扰。针对Cl-/COD≤20的水样,具有较好的准确度和精密度。
COD fast determination method to obtain COD of wastewater with high concentration of chloride was introduced. The methods of HgSO4 accession and dilution were used to avoid disturbance of chloride ion. The results show that It has high accuracy and preciseness for the wastewater of Cl -/COD ≤ 20.
