Determinação turbidimétrica de metilbrometo de homatropina em formulações farmacêuticas empregando um sistema de análise por injeção em fluxo

Autor: Larissa S. Canaes, Orlando Fatibello-Filho

Publikováno v: Química Nova, Vol 29, Iss 6, Pp 1237-1240 (2006)

A flow injection turbidimetric procedure exploiting merging zones is proposed for determining homatropine methylbromide (HMB) in pharmaceutical preparations. The determination is based on the precipitation reaction of homatropine methylbromide with A

Boron-Doped Diamond Electrode Coupled to Liquid Chromatography: Application to Simultaneous Determination of Benzodiazepines

Autor: Isarita Martins, Larissa S. Canaes, Keity Margareth Doretto, Susanne Rath

Publikováno v: Electroanalysis. 22:455-462

The applicability of boron-doped diamond (BDD) as a working electrode in an amperometric cell, coupled to HPLC, was demonstrated, for determining benzodiazepines in pharmaceutical preparations. The separation of the benzodiazepines was achieved using

Flow injection spectrophotometric method for chloride determination in natural waters using Hg(SCN) immobilized in epoxy resin

Autor: Claudineia R. Silva, Larissa S. Canaes, Orlando Fatibello-Filho, Heberth Juliano Vieira, Joaquim A. Nóbrega

Publikováno v: Talanta. 65:965-970

A flow injection (FI) spectrophotometric method was proposed for the determination of chloride ion in natural waters. The determination of chloride was carried out by reaction with Hg(SCN)(2) immobilized in an epoxy resin bead in a solid-phase reacto

Determinação espectrofotométrica de vitamina B2 (riboflavina) em formulações farmacêuticas empregando sistema de análises por injeção em fluxo

Autor: Carla Cristina Schmitt Cavalheiro, Clezio Aniceto, Larissa S. Canaes, Orlando Fatibello-Filho

Publikováno v: Química Nova. 23:637-640

A flow injection spectrophotometric procedure exploiting merging zones is proposed for determining vitamin B2 (riboflavin) in pharmaceutical preparations. The determination is based on the red-colored complex formation between vitamin B2 and silver(I

Determination of parabens in shampoo using high performance liquid chromatography with amperometric detection on a boron-doped diamond electrode

Autor: Isarita Martins, Letícia Maria da Silva Cruz, Franciely Cristiani Carreira, Larissa S. Canaes, Francisco Alberto de Souza Campos Junior, Susanne Rath

Publikováno v: Talanta. 85(1)

Methylparaben (MePa), ethylparaben (EtPa) and propylparaben (PrPa) have been widely used, among others, as chemical preservatives in cosmetics, drugs and foods. As these compounds are linked with allergies, dermatitis and estrogenic properties, it is
