METHOD FOR DETERMINING DINITROSOPENTAMETHYLENE TETRAMINE IN AIR Russian patent published in 1996 - IPC

FIELD: monitoring of environment near industrial enterprises of chemical and rubber industries. SUBSTANCE: air to be tested is fed to filter, material from the filler is then desorbed with water at 30-35 C, 5N cesium chloride solution is then added to the solution and gaseous nitrogen is allowed to pass, and the solution is then polarographed at potential of 1.3 V. Sensitivity of determination is 2 mcg/m of the solution. The measurement limit in air is 0.3 mg/cubic m in 40 l sample. EFFECT: more efficient determination method. 1 dwg
