| Abstract: | M(Ⅱ) OP 5 Br PADAP coloured system and a wavelength pair of 560.0/587.0 nm are used for determining cobalt and nickel.The conditions for the extractive separation of interfering ions are investigated.Double wavelength K coefficient method is applied to determining cobalt and nickel in synthetic samples and heavy oil samples.The recovery rate for the synthetic samples is 94 6% 105 4% and the results for the heavy oil samples agree with that of the standard addition method. |
