| 摘要: |
| 本文介绍用电生 BrO~-离子对亚铵制浆废液的含氮量作库仑滴定。结果表明该方法是可行的,它具有较好的线性关系,并且干扰少、快速、灵敏度高和准确性好等优点。本实验用农大84—1型Vc 测定仪作终点指示器,比用检流计指示终点清晰、准确。同远红外消煮炉联用,作样品消煮,样品需用量少,一次可以同时消煮几十个样品,并且便于自动化。本方法也能用于其他农业样品含氮量的测定。 |

| DETERMINATION OF THE NITROGEN CONTAINED IN WASTE PUIP OF AMMONIUM SUIFITE PROCESS BY COUIOMBIC TITRAION |

| Abstract: |
| The nitrogen contained in the waste pulp of ammonium sulfite pro- cess has been determined with electro-generated Eroion by coulombic titration.The process demonstrated good linear relation,rapidity, sensitivity and accuracy,and it is little interfered by other contents con- tained in the solution. The method may also be used to determine the nitrogen contained in other agriculture products. |
