“…The Br − concentration in the irrigation water was determined by ion chromatography (Tirumalesh, 2008), performed with a high-performance liquid chromatography (METROHM model 881 Compact IC pro), and the limit of detection was 0.1 mg of Br − ·L −1 .…”

Determination of reliable solute transport parameters is an essential aspect for the characterization of the mechanisms and processes involved in solute transport (e.g., pesticides, fertilizers, contaminants) through the unsaturated zone. A rapid inexpensive method to estimate the dispersivity parameter at the field scale is presented herein. It is based on the quantification by the X-ray fluorescence solid-state technique of total bromine in soil, along with an inverse numerical modeling approach. The results show that this methodology is a good alternative to the classic Br − determination in soil water by ion chromatography. A good agreement between the observed and simulated total soil Br is reported. The results highlight the potential applicability of both combined techniques to infer readily solute transport parameters under field conditions. FIG. 4.

“…Furthermore, the amperometric detection can be used for samples with pK values > 7. The amperometric detection method application helps in determining ions such as I − , S 2− , S 2 O 3 2− , SCN − , CN − , or heavy and transition metals [29,30]. Due to the poor selectivity and sensitivity, the refractive index detection is very rarely used in ion chromatography [31].…”

Wastewater analysis is an important area in analytical and environmental chemistry. It can be performed with both the classic wet methods and instrumental techniques. The development of new methods, and modification of the existing ones, constitute a major task for researchers. Ion chromatography plays a predominant role in ion determinations with the instrumental methods. It offers several advantages over the conventional methods, such as simultaneous determinations of alkali and alkaline earth cations and ammonia. Ammonium ions cannot be determined by spectroscopic methods. Ion chromatography has been accepted world-wide as a reference method for analyzing anions and cations in water and wastewater due to the fact that it enables the replacement of several individual wet chemistry methods for common ions with one instrumental technique. The following article describes the principles of ion chromatography, such as stationary phases, eluents, detectors, and sample preparation methods. Moreover, the applications of ion chromatography in wastewater analyses and international standards are presented.

“…Several types of chromatography have been introduced for pollutant detection; namely, high-performance liquid chromatography (HPLC) [31], ionic chromatography [32], and ultra-performance liquid chromatography (UPLC) [33]. Ion chromatography is widely used to analyse nitrate in water [2,34]. .…”

“…Chromatography detection systems include simple UV, fluorimetric, electron capture, electrochemical and mass spectroscopic [2,17,[31][32][33][34][35][36][37]. The popularity of UV detection lies in the simplicity of the approach and the ability to attenuate the detection wavelength.…”
