Use of flow injection analysis for continuous monitoring of river water quality

Abstract

Development of industrial areas must be followed by increased monitoring of industrial wastewater systems. One method for continuous monitoring of water quality is flow injection analysis (FIA). An FIA method does not need to mix the reagents and sample manually as in methods based on conventional spectrophotometry and colorimetry; they are delivered by peristaltic pump to the manifold, and after mixing, they go into the flow cell. The parameters that can be determined by FIA are nitrite, nitrate, ammonia, phosphate, silica, arsenic, and mercury. © 2000 John Wiley & Sons, Inc. Lab Robotics and Automation 12:142–148, 2000
