摘要: Abstract The combination of methyldopa and hydrocholorothiazide are used to treat high blood pressure. present research dealt with the synthesis utilization hexagonal-shaped ZnO nanoparticles (NPs) develop a new, sensitive, exclusive electrochemical sensor for detection methyldopa. Thus, we did our examination on via cyclic voltammetry (CV) method, differential pulse (DPV) technique, chronoamperometry (CH) at molybdenum (VI) complex-ionic liquid–ZnO NP modified carbon paste electrode (MCILZNMCPE) in 0.1 M PBS (pH 7.0) solution. use DPV showed linear dependence peak current pH 7.0 solution their concentration ranging between 0.05 300.0 µM. Then, limit (LOD) has been determined be 20.0 nM Ultimately, utilized detecting presence hydrochlorothiazide by DPV.
