Abstract: The present paper reports the flotation spectrophotometry for the formation of mercury-io-dide complex ion with CV-PVA in the presence of SnCl2to form ion associated substance. It is a high sensitive reaction whose e is 3. 26 ×106L/mol ·cm. Mercury in cigarette and nature water was determinated by this method.
