Water pollution by heavy metals and nitrite ions is a public health concern around the world
because they can degrade the quality of drinking water and cause serious diseases. Lead …

Abstract Lead ion (Pb 2+) is a common environmental contaminant, which causes serious
bioaccumulation and toxicity in human body. In this work, we developed a novel Pb 2+ …

A pencil graphite electrode (PGE) was modified by the electropolymerization of pyrrole-1-
carboxylic acid (Py-CO 2) to form a sensing film of poly (pyrrole-1-carboxylic acid)(PPy-CO …

A sensitive Pb (II) sensor was fabricated based on Co 3 O 4/reduced graphene
oxide/chitosan (Co 3 O 4/rGO/chitosan) nanocomposite modified glassy carbon electrode …

The low permissible concentration of lead ions (Pb2+) in potable water (15 ppb) makes it
even more challenging to develop highly efficient water purification technologies. Adsorption …

The worm-like nitrogen-doped-carbon framework (WNCF) with abundant edge-plane-like
defective sites (EDSs) was synthesized by using natural wax gourd (Benincasa hispida) as …

As a unique strategy, a sensitive urea biosensor media involving dip coated ZnO and Fe 3 O
4 nanocomposite, at the optimized instrumental deposition conditions, on the F-doped SnO …

The synthesis of a series of thiosemicarbazone ligands bearing azido groups, which were
further immobilized on the surface of phenylethynyl-functionalized glassy carbon (GC) …

In this work, the multifunctional hemin/G-quadruplex nanowires formed by rolling circle
amplification (RCA) was used to develop a direct electron transferred electrochemical …

In this article, we present a simple and efficient method to synthesize a magnetic NiFe2O4
nanocatalyst under hydrothermal conditions. Fourier transform infrared spectroscopy (FT …
