我厂采用蒽醌法生产双氧水(H_2O_2),利用国产883型极谱仪分析测定2-乙基蒽醌,4氢-2乙基蒽醌的含量,控制工艺生生,经一年多的使用,实践证明效果较好,现将使用中遇到的几个问题简述如下.1.仪器组装后检查发现记录器不工作,该记录器系EWC型电子电位差计改制,按电子电位差计检修方法检查故障,系记录器 I plant using anthraquinone production of hydrogen peroxide (H_2O_2), the use of domestic 883-type polarographic analyzer for the determination of 2-ethylanthraquinone, 4-dihydro-2-hydroxy anthraquinone content, control of process life, after more than a year of use, Practice has proved that the effect is better, are now encountered in the use of a few problems outlined below .1 After the instrument found that the recorder does not work check, the recorder is EWC-type electronic potentiometer restructuring, according to the electronic potential difference overhaul Method to check the fault, the Department of recorder
