ChemicalOxygen (Demand COD), is a certain condition, the use of a certain strong oxidant treatment of water samples, the consumption of the oxidized dose. It is an indicator of how much water is reduced. The greater the chemical oxygen demand is, the more serious the water is polluted by organic matter. Determination of chemical oxygen demand (COD), with the determination of reducing substances in water samples and the different methods, the determination of the value of the
Tengzhou City Xiangying Analysis Technology Co., Ltd. the XiangyingGC7990plus gas chromatography analysis of the content of organic matter in organic wastewater. The content of organic matter in waste water was determined by external standard method, and the content of COD was determined according to the content of organic matter.
COD即(ChemicalOxygen Demand),是一定的条件下,采用一定的强氧化剂处理水样时,所消耗的氧化剂量。它是表示水中还原性物质多少的一个指标。化学需氧量越大,说明水体受有机物的污染越严重。化学需氧量(COD)的测定,随着测定水样中还原性物质以及测定方法的不同,其测定值也有不
