The possibility of chlorine detection in water by using of amperometric sensor with dialysis membrane was investigated. The sensor consists of platinum cathode and silver anode, which were immersed in electrolyte whose pH was controlled. The calibration diagrams were constructed for different electrolytes and polarization potentials. The detection limit of 0.1 mg/dm3 was obtained, middle value of sensor sensitivity was approximatelly 14 nA/mgdm'3 and response time was less than 1 s for designed amperometric sensor in laboratory conditions
