| Abstract: | This method is band on the principle that chlorine (Cl2)can be quantitatively determined. An abober is used to absorb Cl2 thatis reactive product of k2Cr2O7 and Cl-. Then iodimetry is used to determine the residual chlorine. Thus the interference of cl- is eliminated. This method is of higher accuracy and precision. |

| Keywords: | COD residual chlorine absorber |
