| Abstract: | The determination of oxygen in copper by hot-extraction method gives off its oxygen content mainly as CO and partially as CO_2 But most of the commercial analytical instruments for oxygen determination are designed to detect CO only. The evolution of CO_2 leads to erroneous results. For the suppression of the formation of CO_2, three programs have been studied critically, and the method of reduction inside crucible is found to be most satisfactory, simple and accurate. |
