无银催化微波消解快速测定炼油污水的化学需氧量

Rapid Determination of COD of Refinery Waste Water by Microwave-Sealed Digestion Apparatus Using Silver-Free Catalyst

建立了以CuSO4-MgSO4为催化剂、800W微波功率进行一定时间的微波消解测定炼油污水的化学需氧量的新方法。该方法检测速度快、消耗少、成本低,特别适合批次多、数量大的炼油污水的检测,对其它废水化学需氧量的检测也具有应用价值。

A new technique for measuring COD of refinery waste water with microwave sealed digestion apparatus was developed using copper sulfate as catalyst.The method was rapid,with low consumption and low cost.This method is especially suitable for determining large batches and quantities of refinery waste water.It also has important application value in measuring COD of living waste water and other industrial effluents.
