Constructing a Chlorine Sensor For Use In Developing Nations

Chlorination is the most common approach to disinfecting water, however, it requires a precise concentration level to work effectively. Determining how much chlorine to add is often difficult for these communities due to limitations in current single-use chlorine concentration testing methods. This research project involves the development and testing of a chlorine sensor that can continuously monitor chlorine levels using silver and platinum electrodes. The researcher was able to decrease the size of the sensor and create a calibration curve for reference when adding chlorine. The results of the calibration curve show that the constant chlorine sensor is able to detect smaller changes in chlorine concentration with high precision and accuracy.
