Application of a Lithium-ion Selective Metallacrown to Extraction-Spectrophotometric Determination of Lithium in Saline Water
Abstract The solvent-extraction behavior of $ Li^{+} $ and $ Na^{+} $ with a $ Li^{+} $ selective metallacrown, [{Ru($ η^{6} $-3,5-dimethylanisole) (2,3- pyridinediolate)}3], was investigated in the presence of organic dye anions, 3′,3″,5′,5″-tetrabromophenolphthalein ethyl ester ([TBPE]–), 2,6-dich...

520 | |a Abstract The solvent-extraction behavior of $ Li^{+} $ and $ Na^{+} $ with a $ Li^{+} $ selective metallacrown, [{Ru($ η^{6} $-3,5-dimethylanisole) (2,3- pyridinediolate)}3], was investigated in the presence of organic dye anions, 3′,3″,5′,5″-tetrabromophenolphthalein ethyl ester ([TBPE]–), 2,6-dichloroindophenolate, and picrate ([pic]–). Each alkali metal ion was extracted as a 1:1:1 ternary complex of the metal ion, metallacrown, and anion. The $ Li^{+} $/$ Na^{+} $ extraction selectivity is anion dependent and highest with [pic]–. Therefore, we devised an extraction–spectrophotometric determination method for $ Li^{+} $ in saline water based on the extraction of Li+ using the metallacrown and [pic]– for high selectivity and subsequent replacement of [pic]– in the extracted species with [TBPE]– for high sensitivity. When applying this to artificial seawater samples containing known concentrations of $ Li^{+} $, a linear relationship was observed between the absorbance at 571 nm of the organic phase and the $ Li^{+} $ concentration in the samples. By this method, the determination of $ Li^{+} $ at the sub-ppm level in natural seawater is possible. | ||

Each alkali metal ion was extracted as a 1:1:1 ternary complex of the metal ion, metallacrown, and anion. The $ Li^{+} $/$ Na^{+} $ extraction selectivity is anion dependent and highest with [pic]–. Therefore, we devised an extraction–spectrophotometric determination method for $ Li^{+} $ in saline water based on the extraction of Li+ using the metallacrown and [pic]– for high selectivity and subsequent replacement of [pic]– in the extracted species with [TBPE]– for high sensitivity. When applying this to artificial seawater samples containing known concentrations of $ Li^{+} $, a linear relationship was observed between the absorbance at 571 nm of the organic phase and the $ Li^{+} $ concentration in the samples. By this method, the determination of $ Li^{+} $ at the sub-ppm level in natural seawater is possible.

Each alkali metal ion was extracted as a 1:1:1 ternary complex of the metal ion, metallacrown, and anion. The $ Li^{+} $/$ Na^{+} $ extraction selectivity is anion dependent and highest with [pic]–. Therefore, we devised an extraction–spectrophotometric determination method for $ Li^{+} $ in saline water based on the extraction of Li+ using the metallacrown and [pic]– for high selectivity and subsequent replacement of [pic]– in the extracted species with [TBPE]– for high sensitivity. When applying this to artificial seawater samples containing known concentrations of $ Li^{+} $, a linear relationship was observed between the absorbance at 571 nm of the organic phase and the $ Li^{+} $ concentration in the samples. By this method, the determination of $ Li^{+} $ at the sub-ppm level in natural seawater is possible.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield

Application of a Lithium-ion Selective Metallacrown to Extraction-Spectrophotometric Determination of Lithium in Saline Water |
abstract |
Abstract The solvent-extraction behavior of $ Li^{+} $ and $ Na^{+} $ with a $ Li^{+} $ selective metallacrown, [{Ru($ η^{6} $-3,5-dimethylanisole) (2,3- pyridinediolate)}3], was investigated in the presence of organic dye anions, 3′,3″,5′,5″-tetrabromophenolphthalein ethyl ester ([TBPE]–), 2,6-dichloroindophenolate, and picrate ([pic]–). Each alkali metal ion was extracted as a 1:1:1 ternary complex of the metal ion, metallacrown, and anion. The $ Li^{+} $/$ Na^{+} $ extraction selectivity is anion dependent and highest with [pic]–. Therefore, we devised an extraction–spectrophotometric determination method for $ Li^{+} $ in saline water based on the extraction of Li+ using the metallacrown and [pic]– for high selectivity and subsequent replacement of [pic]– in the extracted species with [TBPE]– for high sensitivity. When applying this to artificial seawater samples containing known concentrations of $ Li^{+} $, a linear relationship was observed between the absorbance at 571 nm of the organic phase and the $ Li^{+} $ concentration in the samples. By this method, the determination of $ Li^{+} $ at the sub-ppm level in natural seawater is possible. © The Japan Society for Analytical Chemistry 2018 |
