摘要：

An advanced monitoring system for controlling the treatment process of wastewater containing chromium(VI) was developed using a flow method as a chemical sensing probe. In this, system, the acquisition of monitoring information and the control of the treatment process is computer-controllable. By application of the system to control the end-point of redox-treatment, an accuracy and precision better than +/- 0.9% (n = 5) and a relative standard deviation smaller than 0.5% (n = 5) were found; furthermore, safe discharge of wastewater can be ensured without the addition of any coprecipitation reagents.
