The invention relates to the technical field of environmental monitoring, in particular to an integrated extraction-spectrophotometric measurement device and measurement method, comprising a sampling unit, a measuring unit and a distillation unit connected in sequence by pipelines, the sampling unit, the measuring unit and the distillation unit Both are electrically connected to the control unit. Compared with the prior art, the present invention reduces the emulsification phenomenon in the extractant by incorporating the extraction operation of the extractant into the measuring cell, and removing the organic phase separation and drying step after extraction. , while ensuring the measurement accuracy and stability of the parameters, the structure of the extraction colorimetric device is greatly simplified, the detection efficiency of the traditional automatic extraction water quality analysis instrument is effectively improved, and the equipment maintenance difficulty and cost are reduced. On-line automatic continuous detection of volatile phenols in water and type II water has broad application prospects. |
