摘要
Abstract
The kinetics of reaction between HNO2 and hydroxysemicarbazide in perchloric acid solution was studied. The rate equation is found to be —dc (HNO2)/dt =kc(HNO2)c0.25 (HSC)c0.42 (H+ ), where k=(1. 05±0. 05) (mol/L)-0.67 · s-1 at 1.0 ℃. The activation energy is found to be (73. 1 ± 3. 0) kJ/mol. Effects of c (HSC), c ( H+ ), ionic strength and temperature on reduction rate of HNO2 were investigated. The results show that HNO2 can be rapidly reduced by HSC under usual conditions. The reaction rate can be accelerated by increasing the concentration of HSC, acidity, ionic strength and reaction temperature.The influence of ClO4- on reaction rate is negligible.关键词
