“…Thanks to ion chromatography, ions such as cyanides and sulfides can be separated and determined simultaneously [45]. Moreover, the chelating agents, such as nitriltriacetate acid (NTA) and ethylenediaminetetraacetic acid (EDTA), and polyphosphates can be analyzed in wastewater [46]. In addition to common inorganic ions, some metals and metalloids can be determined in wastewater with ion chromatography.…”

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.

“…Chromatographic methods are mainly used for separation, whereas spectroscopic methods serve for detection [100]. The ion chromatography applications in speciation analysis can be divided into three main groups: In the literature, there are many described ion chromatography applications for analysis of ions of nitrogen [101], sulfur [102], phosphorus [103], or halide ions [104], also in samples with complex matrices. Due to the ion chromatography development, it is used not only for routine analyses of anions and cations in water and wastewater but also for other analytes.…”

“…If Saha ionization occurred, the amount of emission would increase a little. However the Saha equation only held weakly ionized plasmas for in which the Deby length was large [46,47]. The independency of the scattered light with the Saha phenomenon was evidenced via observation of no significant response during independently analysis of inorganic species such as Na + , K + or H 3 PO 4 .…”

A new method has been introduced based on aerosol hygroscopic growth as a new factor for trace and ultra-trace determination of phosphorous in flame containing optical trapping-cavity ring down aerosol extinction (emission) spectrometer (OT-CRD-AES). In this study, a cavity ring down has been designed using hydrogen and air as fuel and oxidant during introduction of the aerosols containing phosphorous species using an ultrasonic generator (humidifier) from an acidic solution by a flow rate of N 2 , followed by detection of the Mie scattering using a charged coupling device (CCD) system. Parameters having strong influence during following scattering of the aerosols during their hygroscopic growth inside the humidified flame (H 2 /air), include: influence and amount of Na + as radiation buffer (as light source), flow rates of H 2 , air and N 2 , kind and concentrations of acid, evaluation of the aerosols inside flame, etc. These parameters were optimized using simplex and one at a time methods. Based on the figures of merit under optimized condition, two linear calibration curves with reverse slopes were evaluated between 10.0 -250.0 ng mL -1 and 1.0 -20.0 µg mL -1 with correlation coefficients (R 2 ) the same as 0.999 and 0.998, respectively. The calibration sensitivities were also estimated to 57.46 and 0.348 (a.u), respectively, with detection limit of 5.0 ng mL -1 . The mechanism of the radiation (Mie scattering) was also evidenced based on i) dependency of the scattered radiations to the quantity of an alkali ions such as Na+ as well as the humidity, ii) presence of acceptable correlation between the response of the cavity with turbidometry, iii) observation of blue shift from green (color related to the luminescence of HPO* in H 2 /air flame) to blue (scattered radiation) and finally iv) effect of hydration number during stability and growth of the aerosols inside the flames.No serious interference was evaluated during analysis of at least 500-fold excess of various foreign species. However, the only observed interference was evaluated during introduction of 200-fold excess of SO 4 2-. Good correlation was also evaluated between the results obtained from this technique and ion exchange chromatography during analysis of wastewater samples that clearly revealed the reliability of this method for phosphorous detection and determination at µg mL -1 and ng mL -1 levels.
