“…A two-line flow injection system with potentiometric detection was suggested by Lima et al (1996b) for the determination of chloride (Cl) in vegetables. The aqueous extracts were injected in a water carrier stream and next merged with a stream of potassium nitrate (KNO 3 ), methanol, HNO 3 , and sodium chloride (NaCl), with the purpose of adjusting thé ionic strength, reducing interferences from humic substances on the electrode membrane, and stabilizing the baseline.…”

“…No caso da detecção por Uv/vis, os trabalhos descritos na literatura submetem as amostras a um tratamento prévio ou incorporam no sistema FIA unidades de diálise para eliminar vários tipos de interferentes (Leon e Centrich, 1991;Herrero et al, 1992;Morais et al, 1997). Dentro dos sistemas com detecção potenciométrica, uns efectuam a medição directa do cloreto, usando eléctrodos de configuração tubular, sem solução de referência interna, sensíveis ao anião cloreto (Ferreira et al, 1994a;Lima et al, 1996;Pérez-Olmos et al, 1997), enquanto outros utilizam as titulações FIA, usando um eléctrodo sensível ao catião prata, como indicador.…”

“…El FIA por detección potenciométrica se ha aplicado al análisis de cloruros en muchos tipos de aguas según la norma UNE EN ISO 15682: 2002 [102][103][104][105][106][107][108]. También se han usado para la detección del ion cloruro en vegetales [109], en alimentos [110], además de numerosas aplicaciones en el campo de la química clínica y bioanalítica [111].…”
