【摘要】 总有机碳能够完全反映水中有机污染程度,已被许多国家所采用,我国也将它列入"污水综合排放标准"中.文章采用岛津TOC-VCPH分析仪,运用燃烧氧化-非色散红外吸收法测定了福州市辖区的地表水和不同行业工业废水中的总有机碳(TOC).结果表明,该方法检出限为0.06 mg/L,对于TOC浓度在0-100 mg/L范围内水样的测定,相对标准偏差控制在3%以内;具有操作简单、成本较低、灵敏度高,能满足环境水样中TOC项目的监测要求.更多还原

【Abstract】 Total organic carbon can reflect water pollution degree completely,and adopted by many countries and integrated wastewater discharge standard of our country.This paper use burning oxidation-non-dispersive infrared absorption method to detect the total organic carbon(TOC) of Fuzhou City surface water sewage effluent and different kinds of industrial wastewater by Shimadzu TOC-VCPH analyzer.The results showed that the detection limit is 0.06mg/L,and for the analyzing of water samples which TOC concentration in the range of 0-100mg/L,the relative standard deviation can be controlled less than 3%.This method is simple,rapid,low cost,sensitivity can meet the monitoring requirements in TOC detection of environment wastewater.更多还原
