| Abstract: | In this paper CODCr with concentration as low as 1 - 70 mg/L was test by photometry of Diphenylcarhazide with LOD and RSD as 0. 81 mg/L and 6. 2 % respectively. This technology is available to test CODCr with low concentration such as that in effluent of sewage treatment plants, pure water, drinking water and running water. |
