This review presents applications of response surface methodology (RSM) when mixture
experiments are involved for the optimization in the field of analytical methods development …

Chemometric activities in Brazil are described according to three phases: before the
existence of microcomputers in the 1970s, through the initial stages of microcomputer use in …

The new cyclic renewable mercury film silver based electrode (Hg (Ag) FE), applied for the
determination of molybdenum (VI) traces using differential pulse adsorptive cathodic …

A simple, effective, and low‐cost protocol for copper determination in biodiesel, with no
sample decomposition, is reported. Samples were diluted in an ethanol‐water solution (with …

A reliable and very sensitive procedure for the determination of ultra trace of molybdenum is
proposed. Molybdenum was determined by cathodic stripping differential pulse voltammetry …

Bismuth‐film electrodes on glassy‐carbon substrates have been successfully applied for
adsorptive‐stripping voltammetric measurements of trace molybdenum in the presence of …

A new procedure is presented for the simultaneous determination of ultra trace amounts of
vanadium and molybdenum based on adsorptive cathodic stripping voltammetry (AdCSV) …

A method for the voltammetric determination of trace molybdenum using a multi-walled
carbon nanotubes modified carbon paste electrode (MWCNT/CPE) was described. The new …

A sensitive and selective procedure is presented for the voltammetric determination of
copper (II) ion. The procedure involves an adsorptive accumulation of Cu2+‐PPKO on a …

This work illustrates the modeling procedure for a solvent mixture using the simplex-centroid
approach. The selected experiment was the optimization of the peak current observed in the …
