The H-point standard addition method (HPSAM) is a modification of the standard addition
method that transforms the incorrigible error resulting from the presence of a direct …

Two new, simple, relatively fast and robust methods for the simultaneous kinetic
determination of binary mixtures of ascorbic acid (Asc) and cysteine (Cys) were developed …

This review on multi-component kinetic-based determinations covers most publications in
this field during the period 2000–2007. The methodologies applied during recent years have …

A fast and accurate procedure has been researched and developed for the simultaneous
determination of maltol and ethyl maltol, based on their reaction with iron (III) in the presence …

Simultaneous determination of uranium and thorium using arsenazo III as a chromogenic
reagent at pH 1.70 by H‐point standard addition method (HPSAM) and partial least squares …

The interaction between metal complex Cu2+–ARS (Alizarin Red S) and l-cysteine was
investigated via fluorescence and absorption spectroscopies. In pH 5.2 Britton–Robinson …

A new, rapid and highly sensitive and rapid method was proposed for the simultaneous
determination trace levels of vitamin C and folic acid in the human urine samples. The …

This paper proposes an alternative analytical spectrophotometric method for the total
polyphenol quantification in the aqueous extract of plants. When these extracts are added to …

Simple reverse flow injection analysis (rFIA) manifold with spectrophotometric detection was
developed for an indirect determination of ascorbic acid. Parameters such as stability …

A procedure for simultaneous kinetic analysis of a binary mixture of ascorbic acid (Asc) and
