Electrochemical detection of mercury using biosynthesized hydroxyapatite nanoparticles modified glassy carbon electrodes without preconcentration

Abstract

An electrochemical method for the determination of trace levels of mercury(<sc>ii</sc>) ions using <italic>Aloe vera</italic> (Av) assisted hydroxyapatite (HA) nanoparticles modified glassy carbon electrode (GCE) by square wave voltammetry is described for the first time.
