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
<abstract language="eng">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 concentration...
