Chemical sensors in water protection control

摘要

The application of several selective chemical sensors and biosensors for monitoring water quality and thus facilitating water pollution control is described. Any regulation in the field of pollution control and environmental chemistry has to be accompanied by an analysis of the toxic substances. Many hazardous substances require continuous surveillance to determine the current toxicological status and the necessary remedial actions. Chemical sensors designed to detect threshold levels of chemical compounds can perform this function. The sensors require a built-in calibration to produce results which are not biased by interfering compounds. Production of these reliable sensors in great quantities will lower unit costs and make their use more cost- effective.
