| 摘 要： | 在水质ＣＯＤｃｒ快速测定法中，由于取样量仅２．００ｍＬ，对含较多有机颗粒物的浑浊水样，其取样的均匀性、代表性至关重要，否则会带来很大误差。样品置于水浴超声器中作用５ｍｉｎ是一种理想的均化措施。

| Abstract: | Since the quantity to be sampled in a quick determination of COD Cr is only 2.00 mL,the uniformity and typicality of the sample is very critical in case of turbid water sample containing more organic particles,otherwise big errors will be caused.It is an ideal method for uniformization to shake the sample in a water_bath supersonic device for five minutes. |
