| 中文摘要 |
| 在PH为5.5的HCl-(CH2)6N4介质中,铁氰化钾和过二硫酸铵存在下,用4-氨基安替吡啉(4-AAP)两波段光度法可同时测定污水中0.1-30mg/L的酚类和0.008-3.0mg/L的芳胺。水样不需要预镏和萃取操作,石油类及0.3mg/t以下的硫化物不于扰测定,Cu2+、Fe3+的干扰可用EDTA掩蔽消除。酚类和芳胺的水样加标回收率酚类为98%-105%,芳胺为95%-105研究了10种酚和13种芳胺的测定灵敏度。 |
| 英文摘要 |
| A modified spectrophotometric method of determination for phenols and aromatic amines of sewage was discribed.It was found that the Peak ranges of phenols were 300540um and that of aromatic ammes were 530-480 um using 4-aminoantipyrine(4-AAP)with potassium hexacyanoferrate and ammonium Peroxydisulfate in the medium of PH 5.5 HCl-(CH2)6N4.Phenols of 0.1-30 mg/Land aromtic adenes of 0.008-3.0 mg/L were determined simuisneously by spectrophotometry without Ppedisfillation and extraction. Lower than that 0.3 mg/L of sulphide and co-oil in sewage have no interference with determination of phenols and aromatic ammes. The interference of Cu2+ and Fe3+ could be removed by EDTA masking.The recovery for phenols and aromatic adenes were 98%-105% and 95%-105%, respectively.Thesensitivies samples of 10 phenols and 13 aromatic adenes were studied. |
