MACHEREY-NAGEL Test paper Potassium iodate starch from MN
Quick and easy determination of nitrite and free chlorine
This test paper allows the quick and easy detection of strong oxidizers such as nitrite and free chlorine. Potassium iodide starch paper is also used to control diazotization reactions. Nitrite or free chlorine oxidize potassium iodide to form elemental iodine which reacts with starch to a blue-violet complex. Potassium iodide starch paper may be used by dipping it into the sample or by applying drops of the sample onto the paper. To detect gaseous oxidizers, the paper is moistened with distilled water and then exposed to the gas in question.
MN offers three different versions of potassium iodide starch paper:
