Determinação espectrofotométrica em fluxo de cloro em água usando célula de longo caminho óptico e multicomutação Spectrophotometric flow determination of chlorine in water using a long pathlength optic cell and multicommutation
Autor: Fernanda Helena Salami, Viviane Gomes Bonifácio, Orlando Fatibello-Filho, Luiz Humberto Marcolino-Jr
Publikováno v: Química Nova, Vol 32, Iss 1, Pp 112-115 (2009)
A multicommuted method for determination of chlorine in water samples using a 100-cm cell was developed. In this method, orto-Tolidine reacts with chlorine and the product was monitored at 438 nm. The analytical curve for chlorine was linear in conce

Spectrophotometric Multicommutated Flow System for the Determination of Hypochlorite in Bleaching Products
Autor: Geiser Gabriel Oliveira, Fernanda Helena Salami, Orlando Fatibello-Filho, Viviane Gomes Bonifácio
Publikováno v: Analytical Letters. 41:3187-3197
A multicommutation flow system for the spectrophotometric determination of hypochlorite in bleaching products is proposed. In this system, N,N-diethyl-p-phenylenediamine (DPD) reacts with hypochlorite, and the product was monitored at 515 nm. The ana
