“…Furthermore, the flow rate for the second dimension is independent of the first which makes this method relatively flexible. The application of the heart-cutting method was used for example for the analysis of perchlorate in drinking water or HF determination [20][21][22][23][24]. The second method differs insofar that not some specific fractions but the complete eluent is transferred onto the second column.…”

“…Some studies suggest that perchlorate has pulmonary toxic effects as well [4]. Few methods used for the detection of perchlorate are surface enhanced Raman spectroscopy (SERS) [5,6], ion chromatography [7], and impedance spectroscopy [8]. But these methods require expensive instruments, high operating cost, and trained personnel for the analysis.…”

A novel method was designed for the synthesis of polyphenol capped amorphous iron oxide nanoparticles (ION) using an agro waste (peanut skin). The synthesized nanoparticles were characterized by absorption spectroscopy, TEM, SEM, IR, Raman and XRD. An increased rate of formation of the nanoparticles is observed upon low dose gamma irradiation. ION shows specific spectral features with perchlorate anion even in presence of other anions selected for the anion sensing study. The nanoparticles formed in presence of irradiation was found even more sensitive to lower concentration of perchlorate owing to its finely dispersed nature and increased surface area.

“…Therefore, ultra-sensitive analytical techniques are required for quantitative measurement of environmental perchlorate. The technique of twodimensional ion chromatography (2D-IC) with conductivity detection is able to detect perchlorate down to 12 ng L −1 [25][26][27] without pre-concentration. The technique of tandem mass spectrometry with electrospray ionization (ESI-MS/MS) was used to measure perchlorate down to 0.1 μg L −1 in reagent water [28].…”

An ion chromatography-electrospray ionization-tandem mass spectrometry (IC-ESI-MS/MS) method has been developed for rapid and accurate measurement of perchlorate in polar snow and ice core samples in which perchlorate concentrations are expected to be as low as 0.1 ng L(-1). Separation of perchlorate from major inorganic species in snow is achieved with an ion chromatography system interfaced to an AB SCIEX triple quadrupole mass spectrometer operating in multiple reaction monitoring mode. Under optimized conditions, the limit of detection and lower limit of quantification without pre-concentration have been determined to be 0.1 and 0.3 ng L(-1), respectively, with a linear dynamic range of 0.3-10.0 ng L(-1) in routine measurement. These represent improvements over previously reported methods using similar analytical techniques. The improved method allows fast, accurate, and reproducible perchlorate quantification down to the sub-ng L(-1) level and will facilitate perchlorate measurement in the study of natural perchlorate production with polar ice cores in which perchlorate concentrations are anticipated to vary in the low and sub-ng L(-1) range. Initial measurements of perchlorate in ice core samples from central Greenland show that typical perchlorate concentrations in snow dated prior to the Industrial Revolution are about 0.8 ng L(-1), while perchlorate concentrations are significantly higher in recent (post-1980) snow, suggesting that anthropogenic sources are a significant contributor to perchlorate in the current environment.
