Highlights•Pencil graphite electrode (PGE) was modified with porous d-penicillamine (DPA)
functionalized nanocellulose (NC) for the first time.•Characterization of DPA/NC was done …

Redox cyclings between mono-/di-valent copper oxidation states occur in electron transfer
reactions that underlie their biological functions. We report herein a dual channel fluorescent …

A simple and sensitive electrochemical sensor based on graphene quantum dot-modified
pencil graphite electrode (GQD/PGE) was fabricated and used for highly selective and …

We describe a square wave anodic stripping voltammetric (SWASV) platform for the
determination of Cu (II). It is based on the use of amino-reduced graphene oxide (NH 2-rGO) …

It is rather important to not only obtain the better detection efficiency for metal ions, but also
investigate the change of sensitivity and detection limit in the simultaneous detection …

Many industries use copper metal ions (Cu2+ ions), and their salts are utilized as
supplemental materials in both agriculture and medicine. Identifying and monitoring these …

This paper describes the electrodeposition of Cu (II), Fe (III) and Al (III) tetrasulphonated
phthalocyanine tetrasodium salts (Cu (II) TSPc, Fe (III) TSPc and Al (III) TSPc) at gold …

A voltammetric method is proposed to detect hydrogen peroxide in teeth whitening gels. First
the conductive properties of the gels are studied and discussed in absence and presence of …

This paper describes the role of adatoms in the electrochemical behavior of gold electrodes
modified with metal ion tetrasulphonated phthalocyanines (MTSPc). After electrodeposition …

This article describes the voltammetric behaviour of RuCl2 (PPh3) 3 in a methyl
methacrylate (MMA) solution. Acquiring this type of information is only possible when the …
