Voltammetric Determination of Pb(II) by a Ca-MOF-Modified Carbon Paste Electrode Integrated in a 3D-Printed Device

Abstract:
In this work, a voltammetric method based on a metal organic framework
(Ca-MOF)-modified carbon paste electrode for lead determination was
developed. The MOF-based electrode was packed in a new type of
3D-printed syringe-type integrated device, which was entirely fabricated
by a dual extruder 3D printer. After optimization of the operational
parameters, a limit of detection of 0.26 mu g L-1Pb(II) was achieved,
which is lower than that of existing MOF-based lead sensors. The device
was used for Pb(II) determination in fish feed and bottled water samples
with high accuracy and reliability. The proposed sensor is suitable for
on-site analyses and provides a low-cost integrated transducer for the
ultrasensitive routine detection of lead in practical applications.
