- The Deposition of Insoluble Crystals by the Radical Polymerization of Cyanide Ion in Aqueous Solution by the Ultrasonic Irradiation
説明
The chemical reaction which was occurred by ultrasonic irradiation for CN− ion in aqueous solution was examined. The concentration of the CN− ion in aqueous solution decreased from 4.0 × 10−3 mol dm−3 to 3.3 × 10−3 mol dm−3 by 300 min irradiation. While pH value of the ion aqueous solution containing CN− ion increased from 10.40 to 10.97 by the 300 min irradiation. The reaction for the change of the concentration of CN− (or OH−) for ultrasonic irradiation time was almost described with first-order kinetics. Insoluble fine particle with white color formed in the aqueous solution by the ultrasonic irradiation. It became clear that the potassium element was not included in the fine particle from experiment on flame reaction. The fine particles were dissolved at a little quantity in methanol, and it was shown that the proton did not exist in the particles from 1H-NMR measurement using the methanol solution. From FT-IR measurement for the fine particle, the absorption of 1390.4 cm−1 and 1100.2 cm−1 which originated from the stretching vibration of single bond of CN was measured, the absorption of 2075.1 cm−1 which originated from the stretching vibration of triple bond of CN was not measured. It become clear that fine particles were the tabular crystal from the scanning electron microscopy and that it is a macro molecular substance which consists of single bond of C–C and C–N.
