“…In order to better determine the Donnan equilibrium in IEC, this can be simplified, such as regarding the mobile and stationary phases as ideal and ignoring the swelling pressure's influence (11) By utilizing eq 11, the equilibrium concentrations of all of the components in the stationary phase can be calculated. When the Donnan potential Δφ is determined, the determination of this variable is possible through the satisfaction of the electroneutrality condition (12) With the C i in the mobile phase, the equilibrium concentrations C p,i * of aforementioned ions in the resin phase and the resulting Δφ can be both determined by utilizing eqs 10 and 12. Moreover, it can be applied to all ionic species (N i ).…”

A new DTSD-S model (combining the ion-exclusion chromatography-Donnan model and two-step dissociation of sulfuric acid) was developed herein to predict C P,SOd 4 2− and C P,HSOd 4 − in the resin pores during the adsorption and desorption processes. A comparison of C P,SOd 4 2− and C P,HSOd 4 − during the desorption process showed that the tailing phenomenon was affected by the acid concentration. When C H + was lower than 0.9 mol/L, the predominant species in the resin pores was SO 4 2− instead of HSO 4 − , which verified that the sulfuric acid tailing was caused by SO 4 2−. The results of energy-dispersive spectroscopy and X-ray photoelectron spectroscopy of the resins after adsorption showed the existence of extra S element, which further verified that the existence of SO 4 2− was the main factor that caused the acid tailing. Finally, we concluded that the acid tailing was inevitable and suggested that one could recover a high H 2 SO 4 concentration by using a high feed acid concentration.

“…Examples of applications of IC in beer analysis are described in the literature, such as biogenic amines determination in alcoholic beverages by IC with suppressed conductivity detection and integrated pulsed amperometric detection (De Borba and Rohrer, 2007), or the analysis of anions in beer using suppressed ion chromatography (Bruce, 2002). Kozaki and his co-workers applied ion-exclusion chromatography and suppressed IC for simultaneous determination of organic and inorganic ions, and ethanol in beers (Kozaki et al, 2019). The application of capillary electrophoresis for simultaneous determination of organic and inorganic ions in beers lead to the separation of 37 ions (3 inorganic anions, 8 inorganic cations, 10 biogenic amines, and 16 amino acids) in beer samples (Guo et al, 2019).…”

Reliable determination of various components of beers is still a challenge due to their complex matrices. Inorganic ions are very important components of beer; their content depends mainly on the quality of water and additional substances used in the brewing process. The major inorganic anions (F-, Cl-, NO2-, NO3-, PO43-, SO42-) and cations (Na+, K+, Mg2+ and Ca2+) were determined using isocratic ion chromatography with conductivity detection. Method optimization involved six ion-exchange columns; different eluent concentration and flow rates were tested. Optimized methodologies allowed for quick, selective and reliable analysis of these ions in 30 beers available on the Polish market. They were characterized by pH values from 3.19 to 4.64, and conductivity from 1632 to 2662 µS/cm. The content of inorganic anions ranged from 0.2 - 1.1 mg/L for F-; 8 - 235 mg/L for Cl-; NO2- < LOD; 7 - 22 mg/L for NO3-; 44 - 188 mg/L for PO43-, and 10 - 95 mg/L for SO42-. In case of cations, it was 10 - 93 mg/L for Na+; 87 - 329 mg/L for K+; 54 - 329 mg/L for Mg2+, and 10-89 mg/L Ca2+. PCA Principal Component Analysis helped in establishing similarities between the analyzed samples.

“…Therefore, IEC/CEC is often applied to determine the presence and/or concentration of common anions and cations in the environmental water, such as acidic rainwater, river water, and dam lake water samples [11][12][13]. When an analytical sample contains phosphate ion, a visible detector based on the molybdenum-yellow or molybdenum-blue reaction is used as post-column derivatization to detect the phosphate ion individually, following the IEC/CEC separation with a conductivity detector [14,15]. However, such a system requires an additional detector (e.g., a visible detector operating at 370 or 510 nm of wavelength), one or two pumps for delivering the reagents, and a reaction coil for enhancing the colorimetric efficiency.…”

In this study, ion-exclusion/cation-exchange chromatography (IEC/CEC) using dual-ion-exchange groups (carboxy and sulfo groups) for the simultaneous determination of anions (SO42−, Cl−, NO3−, and HPO42−) and cations (Na+, NH4+, K+, Mg2+, and Ca2+) was developed. By using the combination of dual-ion-exchange groups, simultaneous separation of inorganic ions with HPO42− was achieved that was impossible by the conventional IEC/CEC based on the single-ion-exchange group (carboxy group). This method was applied to the monitoring of inorganic ionic nutrients in fertilizer solution samples in hydroponic culture. As a result, a higher peak resolution of inorganic anions and cations with phosphate ion using IEC/CEC with dual-ion-exchange groups was achieved in the absence of matrix effects. In addition, the developed method helps to understand the behavior of ionic nutrients in fertilizer solution during hydroponic cultivation and is potentially useful for the individual fertilization of ionic nutrients.
