Abstract

A real‐time, field‐portable derivative UV‐absorption spectrometer (DUVAS) has been designed, built, and tested as a wastewater monitor. Although emphasis is placed on its use at coal conversion facilities, the monitor has applicability in a variety of industries. The instrument is microcomputer‐controlled, providing a variety of operating modes. Laboratory and field measurements have been conducted using the prototype instrument. Among the Environmental Protection Agency's priority pollutants of environmental concern contained in the water streams produced and/or utilized at various coal conversion and other industrial plants are phenols, cresols, and xylenols. This instrument is useful as a real‐time, field‐portable monitor for phenolics at ppm concentrations.

Key words:

• spectroscopy
• wastewater
