This paper describes the development a novel 8,9-dihydroxy-7-methyl-12H-benzothiazolo[2,3-b]quinazolin-12-one -ZnO/CNTs modified carbon paste electrode (DMBQ/ ZnO/CNTs/CPE)for the electrocatalytic determination of hydroxylamine (HX) in the presence of phenol (PL) and sulfite (ST) in water and waste water samples. We describe synthesis and characterization of ZnO/CNTs nanocomposite with different methods such as Scanning electron microscopy (SEM); Energy-dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). Result shows for the mixture containing HX, PL and ST, the peaks potential well separated from each other. Their square wave voltammetrics (SWV) peaks current increased linearly with their concentration at the ranges of 0.09–350, 0.5–500 and 0.7–400 ?M, respectively with the detection limits of 0.04, 0.1 and 0.3 ?M, respectively. The modified electrode was successfully used for the determination of the analytes in real samples with satisfactory result
