This study is focused on the feasibility that utilized the sealed spectrophotometer to measure the CODCr of bleaching effluent. The results of t-test demonstrates that it can be used for the measurement of CODCr the same as the method described in standard method,and the Pearson coefficient is 0.999 5.
Key words: spectrophotometer; bleaching effluent; sealed tube method; COD
