A novel, rapid, and facile electrochemiluminescence sensor which based on carboxylated acetylene black / Ru(bpy)(3)(2+) / nafion modified glass carbon electrode (CAB/Ru(bpy)(3)(2+) /NAF/GCE) was developed for detecting isoniazid (INH). The CAB/Ru(bpy)(3)(2+) /NAF/GCE expresses an efficient electrochemiluminescence response for INH, because of the brilliant luminous efficiency of Ru(bpy)(3)(2+) and admirable electronic transmission of acetylene black. The electrochemiluminescence intensity was quenched significantly with addition of INH. Under the optimal conditions, the sensor for the detection of isoniazid exhibits a wide linear range of 1.0 x 10(-6) similar to 1.0 x 10(-3) mol.L-1 with the detection limit of 5.0 x 10(-7) mol.L-1 The sensor is expected to be a simple and convenient method for the determination of INH in pharmaceutical samples
