“…A carrier element in large quantities must be used in conventional coprecipitation methods in order to form a precipitate which collects the metal ions on its own from aqueous solution. Therefore, the occurrence of interference is inevitable during the measurement of metal ions because of large quantities of a carrier element in the medium .…”

A new separation and pre‐concentration method was presented in this study for two trace heavy metal ions, lead (Pb2+) and cadmium (Cd2+) from aqueous solutions, based on a carrier element free co‐precipitation (CEFC) method using a triazole derivate, 3‐(4‐tert‐butylphenyl)−5‐phenyl‐4‐(2‐hydroxy‐5‐methoxybenzylamino)−4H‐1,2,4‐triazole as an organic co‐precipitating agent. The method was optimized with some analytical parameters which affect the quantitative recoveries of study metals. According to the results, optimum pH of solution, quantity of co‐precipitating agent, centrifugation and incubation time, and sample volume were determined as 6.0, 1.5 mg, 10 min, and 10 min, and 100 mL, respectively. In addition, no significant matrix interferences were observed over the recovery of the metal ions. For analytical figure of merit, RSD values of the method were found as 5.7 and 4.8 for Pb2+ and Cd2+, respectively. LOD values were also calculated as 2.0 µg L−1 for Pb2+ and 0.2 µg L−1 for Cd2+. The accuracy of method was checked with spiked/recovery tests and analysis of a standard reference material. The developed method was finally applied to the real liquid/solid samples under the optimum conditions. © 2016 American Institute of Chemical Engineers Environ Prog, 35: 1709–1715, 2016

“…The comparison of the proposed study with other recent coprecipitation methods [1,[45][46][47][48][49][50][51][52][53][54] for trace metals is summarized in Table 6. The optimum parameters obtained were comparable with those presented by other methods described in the literature.…”

“…In recent years, a new coprecipitation method without the need for a carrier element has been established, and thus this method has been called "carrier element free coprecipitation" (CEFC) [1]. The CEFC method has significant importance for separating and preconcentrating heavy metals because it does not have contamination or background adsorption risks for metal ions from a carrier element [1,[45][46][47][48][49][50][51][52][53][54].…”

“…The LOD was 1.32 ng L À1 (3s) and the precision (n ¼ 11) at 1.0 mg L À1 0.83% (RSD). Another method 191 for the preconcentration of Au from anodic slime, gold ore, soil and waters samples was based on coprecipitation with a 1,2,4-triazole derivative and had a FAAS LOD of 0.36 pg L À1 Au and a RSD of 5.1%.…”

This is the 29th annual review of the application of atomic spectrometry to the chemical analysis of environmental samples. This Update refers to papers published approximately between September 2012 and July 2013 and continues the series ofAtomic Spectrometry Updates (ASUs) Developments in geochemical analysis included the production and (re)certification of new geological RMs for bulk, isotopic and microspatial analysis. Optimisation of LA-ICP-MS techniques for the interrogation of geochemical samples continues to be reported and a number of useful instrumental review articles (AMS, ICP-MS and SIMS) have been published.Feedback on this review is most welcome and the review coordinator can be contacted using the email address provided. Sampling techniquesThe development of personal workplace air samplers, used to monitor workers' exposure to airborne particles, continues to be a fertile area of research. cartridge assembly which could then be loaded directly into an XRF system for analysis. Initial wind tunnel tests using test aerosols of known particle size indicated that this sampler could collect representative particle size distributions.Generation of test particle atmospheres in a laboratory environment is difficult and it is most informative to see publications describing the development and validation of aerosol test chambers. A system 21 for source characterisation and controlled human exposure to NPs generated during gas-metal arc welding had an airtight 22 m 3 climate-controlled stainless steel chamber at its core. A variety of online measurements, e.g. using TEOM or SMPS, and offline measurements, e.g. using electron microscopy and PIXE techniques, could be made via sampling ports/samplers. Test particles were generated in a separate chamber and subsequently piped into the main chamber. Stable concentrations of atmospheric particles could be maintained for up to 6 h and concentrations could be varied from <5 µg m by EDXRF spectrometry (Cr, Cu, Fe, Ni, Pb and Zn), there were no significant differences in values between the two measurement approaches (paired t-test, p > 0.2, 95 % CI). In summary, the authors concluded that this method was suitable for the high throughput analysis of lightly loaded air filter samples. 11The bioaccessible metal fraction in urban aerosol particles may be a more informative metric than the total metal composition in assessng the potential health effects of exposure to inhaled particles. . Using this optimised method, the airborne levels of Ag in Buenos Aires was determined to be 2-4.5 ng m , respectively. Emission spectroscopyInvestigation into the use of LIBS for the analysis of aerosol samples is a focus of a number of research groups. Elemental emission intensities were normalised to carbon (measured at 247.856 nm) which could be used as an internal standard because the carbon emission from the underlying nylon filter was much larger and relatively more stable than the signal from the deposited carbonaceous particles. This approach was useful for minimising shot-to-...
