【Abstract】 A simple,rapid method for detecting CN - in water is described. Based on the principle of chlorimetric analysis and vacuum process design, complex detection method in lab. and operating procedure are fused into a detector tube. Detecting a sample needs only several min. The cost of this method is low. The detection range of the tube for CN -is 0.005—0.20 mg/L.更多还原
