摘要
从氧气流量、进样步骤、催化剂、仪器气密性及空白试验等方面对影响煤中氢元素测定的因素进行详细分析,以降低电量法测氢的过程干扰及提高煤中氢测定的准确性。
From aspects such as oxygen flow, sample entering procedure, catalytic agent, gas tightness and blank experiment, the influencing factors of hydrogen determination in coal was analyzed in detail, so the process interfering of coulometry method for hydrogen determination could be decreased, and the accuracy could be improved at the same time.
