| 中文摘要 |
| 本文研究了鲁米诺-H2O2(KOH,H3BO3)发光体系和苯酚对该体系发光的淬灭作用。发现苯酚浓度处于2.0×10-6—2.0×10-4mol·L-1时,与淬灭后的相对发光强度有线性关系,本法最低检出限为0.2mg·L-1。用于工业废水中苯酚的测定,测定结果满意。 |
| 英文摘要 |
| Trace phenol was determined by measuring phenol-quenched light emission from luminol oxidation by hydrogen peroxide.The detection limit was 200 ppb. A linear response was observed with the concentration of phenol ranging from 2.0×10-6 mol/L to 2.0×10-4 mol/L. The method was successfully applied to the analysis of several waste water samples. |
