| 中文摘要 |
| 研究了乙醚萃取,10%NaOH溶液和10%HCl溶液反萃取,4-氨基安替吡啉(4-AAP)双波长光度法同时测定污水中酚类和芳胺含量的分析方法,提高了测定灵敏度,有效地消除多种干扰物质的干扰,可测定0.003-6.0mg·L-1的酚类和0.0008-0.5mg·L-1的芳胺。加标回收率,苯酚101%-108%,苯胺96%-107%.酚类测定与国标的相对误差≤6.5%.芳胺类测定结果与相应国标法的相对误差在±5%左右。 |
| 英文摘要 |
| This paper deals with a method of simultaneous determination of phenols and aromatic amines which extracted by ether,then reextracted by 10% NaOH and 10% HCl respectively.The sensitivity is improved highly,and many kinds of interferences is removed efficiently.Phenols of 0.03-6.0.mg/L and aromatic amines of 0.008-0.5mg/L can be determined. |
