process, theCOD(chemical oxygen demand)value, which is set at 2 000, is only a mean value. legco.gov.hk legco.gov.hk 因此,正如剛才所說,在抽取樣本的過程中,我們之前將COD(化學需氧量)的數值定於相等於 2 000,是一個平均數。 legco.gov.hk ...
An apparatus for measuring chemical oxygen demand (COD) based on the principle of flow injection analysis (FIA) is described. The apparatus is simple and inexpensive, and constructed by components such as a double plangent pump, sampling valve, flow cell, spectrophotometer and recorder, ...
