Development of New Technique for the Continuous Monitoring Of Chlorine in Drinking Water

Abstract

It is necessary to measure the chlorine level in the water before its use for the drinking purpose.An automated method for routine measurement of chlorine level in water has been developed using photovoltaic detector coupled with a monochromatic pink colored light emitting diode as a source of light. The detected signal has further conditioned and processed by the operational amplifier and ARM processor respectively. The software has been developed for the functions-adjustment of 100% transmittance for reference, measurement of transmitted light intensity and its conversion into absorbance, look-up table of optical densitiesof standard solutions, and finally estimation of unknown concentration. Conventional colorimetric method were simplified for this technique. The technique has the advantage of continuous monitoring and low detection limit. Theanalyzer based on thepresent technique has been successfully used for the monitoring of chlorine level. The analyzeris handheld and suitable for the field work.
