순환전압전류법과 벗김전압 전류법을 사용한 폭발물(hexahydro-1,3,5-trinitro-1,3,5-triazine, RDX)의 흔적량 분석을 위하여 double-stranded ds calf thymus (DNA)와 카본 나노튜브 혼합 전극을 사용하였으며. 최적 분석 조건을 시험한 결과 0.2 V vs. Ag/AgCl 전위에서 봉우리 전류를 발견하였다, 이 전위를 사용하여 선형분석 농도 범위: 50-75 ug/의 순환전압전류법과, 5-80 ng/L의 벗김 전압 전류법에 도달하였으며, 10 ug/L의 농도에서15번 반복 측정한 상대 표준편차는 0.086% 이었다. 또한 300초의 벗김 분석 조건에서 0.65 ng/L (
Cyclic voltammetry (CV) and square wave stripping voltammetry (SW) analysis of hexahydro-1,3,5- trinitro-1,3,5-triazine (RDX) using the double-stranded ds calf thymus (DNA) mixed in carbon nanotube paste electrode (PE) were provided. The optimum analytical conditions were determined and the peak potential was 0.2 V vs. Ag/AgCl. The linear working ranges of CV (50-75 ug/L) and SW (5-80 ng/L) were obtained. The precisions of RSD in the 10 ug/L was 0.086% (n=15) and the detection limit was 0.65 ng/L (2.92×10−12 M) (S/N=3) with 300 s adsorption time at the optimum condition. The method was used to determine the presence of explosive chemicals in contaminated soil samples.
