“…These wide applications based on various areas produce a requirement for increased selectivity and sensitivity to detect the halogen anion. Several methods including laser-induced breakdown spectroscopy [10], ion chromatography [11] and fluorescence technology [12,13] have been used for the determination of halogen anion. The drawbacks of these methods are that they are expensive, time consuming, require large sample volumes as well as large amount of organic solvent with separation and extraction procedures, and must be undertaken by an analytical chemist in a dedicated analytical laboratory.…”

“…Twom ethods, ion chromatography (IC) and UV/Vis spectroscopy,a re commonlyutilized in practice. [61][62][63][64] IC is ac hromatography technique that separates ions and polar moleculesb ased on their interaction with ar esin, and consequently measures the concentrations of ionic species according to their affinity to the ion exchanger.T he IC setups are capable to quantify the concentrations of major anions, including Cl À ,F À ,B r À ,N O 3 À ,a nd SO 4 2À ,a nd major cationsi ncluding Li + ,N a + ,N H 4 + ,K + ,C a 2 + ,a nd Mg 2 + ,a sw ell as some organic acids. The resolution of IC can be as high as parts-per-billion (ppb) range.…”

“…12,13,15,33 Cabe destacar que, com o aumento da massa de amostra e uso de IC com detector por condutividade, é possível reduzir o LOD para até 0,3 µg g -1 . 16 Entretanto, como a concentração de cloreto em cimento é, na maioria dos casos, superior a 20 µg g -1 , 8,16 o método de preparo da amostra utilizando piroidrólise é adequado para a determinação espectrofotométrica de cloreto em cimento.…”
