산성용액중에서 중금속이온의 침전제로 널리 사용되는 Nitrosophenyhydroxylamine(Cupferron)의 비가역전극반응의 전류전압곡선과 산성 및 알카리성에서의 환원반응기구 및 반응속도 그리고 pH변화에 따른 관여전자수, 활성화 energy를 Delahay방법을 이용하여 구하였다.

The ammonium salt of Nitrosophenylhydroxylamine "called cupferron", is a well-known analytical reagent, which precipitates a great number of metal ions in acid medium. The electrode reduction velocities of cupferron at droping mercury electrode in various supporting electrolytes were measured by Delahay method. The free energy of activation and transfer coefficient for a given electrode reaction are computed from the corresponding current-voltage curve. The number of electrons involved in the rate determining step of the reduction of cupferron is calculated for solutions of various pH.
