摘要
本法用BF_4^-电极作指示电极,双液接饱和甘汞电极作参比电极,用十六烷基三甲基氯化铵(CETAC)或氯代十六烷基吡啶(CPC)电位滴定用水提取的复合推进剂中的高氯酸铵。其平均回收率达99.75%,准确度和精密度优于中和法(甲醛法)。
The method presented here for the potentiometrie titration of ammonium perchlorate in composite propellants uses cetyltrimethylammonium chloride (CETAC) or cetylpyridinium chloride (CPC) as the titrant. The titration is performed with a fluoroborate ion-selective electrode as the indicator electrode and a double-junction calomel electrode as the reference electrode. This new method is suitabie for the determination of NH_4ClO_4 in a variety of propellants, with this method the mean recovery and σ attain values better than 99.74% and 0.24 respectively.
