摘要：NOVELTY - A reagent comprises releasing agent and color developing reagent, where the releasing agent comprises diammonium phosphate, potassium (0.52-0.66 g), methyl cellulose (0.03-0.06 g), de-ionized water (2-3 ml), lactic acid with acetone mixed solvent (2-3 ml) and chloramine T (0.02-0.03 g) and volume ratio of lactic acid and acetone is 1:9. The developing agent comprises sodium hydroxide (0.8-1.3 g), isonicotinic acid (1.7-2.3 g), barbituric acid (0.8-1.2 g), methyl cellulose (0.2-0.4 g) and de-ionized water (1-2 ml) and the releasing agent and the color developing agent are independently added. USE - Reagent for detecting cyanide concentration in water. ADVANTAGE - The reagent effectively detects cyanide concentration in a convenient and rapid manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing cyanide concentration detecting reagent.
