Electrochemical determination of phenothrin in fruit juices at graphene oxide-polypyrrole modified glassy carbon electrode
Tefera, Molla; Tessema, Merid; Admassie, Shimelis; Iwuoha, Emmanuel I.; Waryo, Tesfaye T.; Baker, Priscilla G.L. (Elsevier, 2018)An electrochemical sensor was developed based on graphen oxide-polypyrrole modified glassy carbon electrode (GO/PPy/GCE) for sensitive determination of phenothrin in fruit samples. GO/PPy/GCE was characterized by scanning ... -
Sensitive electrochemical determination of ethambutol in pharmaceutical formulation and human urine at nickel nanoparticles/electrochemically reduced graphene oxide modified electrode
Mekassa, Birhanu; Baker, Priscilla G.L.; Chandravanshi, Bhagwan Singh; Tessema, Merid (Chemical Society of Ethiopia, 2019)This paper describes the application of nickel nanoparticles decorated electrochemically reduced graphene oxide modified glassy carbon electrode (NiNPs/ERGO/GCE) for the determination of ethambutol (ETB), an anti-Mycobacterium ...
