“…Therefore, it is necessary to develop the analytical method of alkaline earth metal ions. Several analytical methods such as atomic absorption spectrometry , fluorescence spectrometry , inductively coupled plasma , enzyme analysis , biosensor , and ion chromatography (IC) have been developed for the determination of alkaline earth metal ions. At present, the separation and detection of alkaline earth metal ions using IC with conductivity detection have gradually become well established, but the separation and detection method for IC with UV detection has been relatively reported few times .…”

A convenient and versatile method was developed for the separation and detection of alkaline earth metal ions by ion chromatography with indirect UV detection. The chromatographic separation of Mg , Ca , and Sr was performed on a carboxylic acid base cation exchange column using imidazolium ionic liquid/acid as the mobile phase, in which the imidazolium ionic liquid acted as an UV-absorption reagent. The effects of imidazolium ionic liquids, detection wavelength, acids in the mobile phase, and column temperature on the retention of Mg , Ca , and Sr were investigated. The main factors influencing the separation and detection were the background UV absorption reagent and the concentration of hydrogen ion in ion chromatography with indirect UV detection. The successful separation and detection of Mg , Ca , and Sr within 14 min were achieved using the selected chromatographic conditions, and the detection limits (S/N = 3) were 0.06, 0.12, and 0.23 mg/L, respectively. A new separation and detection method of alkaline earth metal ions by ion chromatography with indirect UV detection was developed, and the application range of ionic liquids was expanded.

“…Commonly weak organic acids such as citric acid, oxalic acid, PDCA, reduce the positive charge of metal cations and increase the separation speed and efficiency. These acids form, preferentially anionic or cationic complexes, which can be separated into cationic and anionic columns [15,[19][20][21].…”

“…Ion chromatography (IC) is fast, convenient, having good selectivity, strong anti-interference ability, allowing multicomponent simultaneous separation and is widely used. At present, the separation and detection of alkali metal ions using IC with conductivity detection has gradually become well established [3][4][5][6][7][8][9]. As a general application in laboratory, UV detector has been widely paired with liquid chromatograph, but the separation and detection method for IC with UV detection is relatively few reported [10].…”

Indirect ultraviolet detection was conducted in ultraviolet-absorption-agent-added mobile phase to complete the detection of the absence of ultraviolet absorption functional group in analytes. Compared with precolumn derivatization or postcolumn derivatization, this method can be widely used, has the advantages of simple operation and good linear relationship. Chromatographic separation of Li(+) , Na(+) , K(+) , and NH4 (+) was performed on a carboxylic acid base cation exchange column using imidazolium ionic liquid/acid/organic solvent as the mobile phase, in which imidazolium ionic liquids acted as ultraviolet absorption reagent and eluting agent. The retention behaviors of four kinds of cations are discussed, and the mechanism of separation and detection are described. The main factors influencing the separation and detection were the background ultraviolet absorption reagent and the concentration of hydrogen ion in the ion chromatography-indirect ultraviolet detection. The successful separation and detection of Li(+) , Na(+) , K(+) , and NH4 (+) within 13 min was achieved using the selected chromatographic conditions, and the detection limits (S/N = 3) were 0.02, 0.11, 0.30, and 0.06 mg/L, respectively. A new separation and analysis method of alkali metal ions and ammonium by ion chromatography with indirect ultraviolet detection method was developed, and the application range of ionic liquid was expanded.
