| 摘 要： | 2008年5月21～26日在辽宁省盘锦市辽河油田境内的双台子河和绕阳河,沿河流采集了水体样本28个,并且利用取自辽河油田的稠油和稀油标样,以及污水处理厂自然污水,进行水槽配比试验,获取不同油浓度水体样本9个;在此基础上,利用红外分光光度计测定水样中的石油类污染浓度和其在3.04～.1μm(波数2 400～3 300 cm-1)波长范围内的透过率;采用朗伯-比尔(Lamber-Beer)定律,计算吸光度,分析有石油类污染水体在中红外波段3.0～4.1 μm(波数为2 400～3 300 cm-1)的吸收特征.研究结果表明:(1)水体石油类污染在中红外的吸收特征主要体现在3.3～3.7μm(2 700～3 000 cm-1)范围内,在3.0～3.3μm(2 400～2 700 cm-1)和3.7～4.1μm(3 000～3 300 cm-1)表现不明显;(2)在3.3～3.7μm(2 700～3 000 cm-1)范围内有两个吸收峰,较强的吸收峰约位于3.412 μm(2 925 cm-1)处,次强的吸收峰约位于3 502 nm(2 850 cm-1)处;(3)在3.3～3.7 μm(2 700～3 000 cm-1)范围内,随着波长变化,石油类物质吸收光谱曲线呈现规则的变化趋势,随着浓度的增加,吸收峰强度增强.本研究结果对于拓展中红外波段在探测水体油膜以及水环境和土壤石油类污染方面的应用可提供一定的参考. |

| Abstract: | The field work was made along the rivers located in Panjin city,Liaoning province of China from May 21 to 26th,2008.In situ a total of 37 water samples were collected in two ways.One was to collect 28 samples from two rivers,another was to collect 9 samples from the experiment,in which the standard oils and sewage obtained from sewage-pool were blended with the water of the rivers.Based on the samples,the petroleum pollution concentration and transparency were measured with the infrared spectrophotometer.Ac... |
