“…Usually, the choice of the sample preparation method depends on the physical state of the sample and the sample matrices, as well as availability of the apparatus configurations [37]. The typical sample preparation methods for ion chromatography analyses are: filtration, dilution, pH adjustment, derivatization, liquid-liquid extraction, solid-phase extraction, distillation, and membrane separations [38].…”

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.

“…However, the addition of a base for neutralization prevents the determination of the added cation and leads to an increase in the salt load, which can also interfere with chromatographic separations. One solution is the use of ion exchangers (in microcolumn or membrane-based configurations), which in their acidic or basic forms can neutralize alkaline or basic solutions, respectively, without reagent addition and without dilution [45].…”

Ion chromatography (IC) is one of the most used analytical methods for the determination of inorganic cations and anions, as well as organic ions. It is considered a method of separation with simple steps, low cost and with good efficiency in chromatographic separation. In addition, it has good validation metrics such as sensitivity, selectivity, precision, robustness, low detection limit and quantification. IC easily replaces conventional wet chemistry methods, which tend to have more analysis steps. The easy extraction of samples, in most cases, does not require organic solvents, facilitating the disposal of waste. Since its creation, IC has accumulated advantages and good acceptance in the food, pharmaceutical, environmental monitoring industries, in addition to increasing implementation in academic research laboratories.

“…Determination -often mistakenly identified with analysis -ends the procedure in which one of the most important stages is sample preparation. The proper way of sampling, storing and preparing the sample for analysis is an important part of the final success, which is a reliable result of analysis (Frenzel and Michalski 2016). Due to the state of sample aggregation, sample preparation in ion chromatography can be divided into methods dedicated for:…”

Due to the increased environmental awareness, green chemistry becomes an important element of environmental protection. Unfortunately, it generate specifi c environmental costs, which are related to the use of toxic chemical reagents and waste generation. The most frequently determined analytes include inorganic and organic anions and cations. The methods used so far for their analysis in water, sewage and various other types of samples are increasingly being replaced by ion chromatography methods. This paper presents the most important advantages and limitations of ion chromatography in the context of "green analytical chemistry." The progress of ion chromatography in gradient and isocratic elution, capillary and multidimensional ion chromatography, as well as miniaturization and methods of sample preparation for analysis, which allow to classify this technique as green analytical chemistry, are described.
