阐述用电导法测煤矸石中碳含量的条件,燃烧温度为1000℃,氧气流量为150～200ml/min,电导液为0.01mol/LNaOH溶液。每次测定前应以高纯CaCO_3测定仪器工作系数K。方法简便、准确。
The conditions for measuring carbon content in coal gangue by electric conductivity method are described. The combustion temperature is 1000 ℃, the oxygen flow rate is 150 ~ 200ml / min and the conductivity liquid is 0.01mol / L NaOH solution. Before each determination should be high purity CaCO_3 instrument operating factor K. The method is simple and accurate.
