WebThe newly developed square wave anodic stripping voltammetry method exhibited wide linearity (0.05 to 20 ng mL −1, r = 0.991), a low limit of detection (0.015 ng mL −1) and … WebIn this study, an effective method for accurately detecting Pb(II) concentration was developed by coupling square wave anodic stripping voltammetry (SWASV) with support …
WebWe then used unmodified graphene/PLA electrode to quantify Hg, and Pb and Cd in 0.01 M HCl and 0.1 M acetate buffer using square wave anodic stripping voltammetry. We were able to quantify Hg with a limit of detection (LOD) of 6.1 nM (1.2 ppb), but Pb and Cd did not present measurable peaks at concentrations below ~400 nM. WebAnodic stripping voltammetry (ASV) is an electrochemical technique in which information about an analyte is derived from the measurement of current as a function of applied potential. The measurement is performed in an electrochemical cell under polarizing conditions on a working electrode, which is normally a mercury or gold film-coated, glassy …
