“…Among the chemical variables affecting the pre-concentration process, the solution pH has a critical role in the effective interaction of the analyte of interest and the adsorbent [4,19,20]. For this purpose, 10 mL of cobalt(II) solutions (50.0 μg L -1 ) buffered in the pH range of 4.0-8.5 were passed through the packed mini-column at a flow rate of 3.3 mL min -1 .…”

“…The sample volume is one of the important factors that affects the pre-concentration factor [4,5]. To study the effect of loading time (sample volume) on the analytical signal, different volumes (from 5.0 to 50.0 mL) of cobalt solution with concentrations of 20, 50, and 100 µg L −1 were passed through the column, and quantitative determinations were made.…”

“…Up to now, different analytical methods have been reported for the quantitative determination of a metal in various matrices. Among the cited methods, flame atomic absorption spectrometry (FAAS) is a popular technique because its accuracy and precision is high and its cost is low [4,6]. However, the sensitivity of this method limits its application [1,6,7].…”

“…However, the sensitivity of this method limits its application [1,6,7]. To resolve this problem, different separation and pre-concentration techniques such as solidified floating organic drop microextraction (SFODME) [8], hollow fiber-liquid phase microextraction (HF-LPME) [9], dispersive liquid-liquid microextraction [10], and solidphase extraction [4,5,11] have been developed to enrich the analyte concentration to an appropriate concentration. Due to the high pre-concentration factor, low cost, low solvent usage, and off-line and on-line operation chance, solid-phase extraction (SPE) is an excellent pre-concentration method [4,11,12].…”

“…Thus, they can lead to serious ecological and health problems even at trace levels [1,2]. Cobalt is one of these elements, which surplus in the concentration of it, can cause asthma, gastrointestinal tract irritation, rhinitis, prohibition of enzyme activities, allergic dermatitis vasodilation, and cardiomyopathy [3][4][5]. According to the World Health Organization (WHO), the maximum acceptable cobalt concentration in drinking water is40 µg L -1 [3].…”

This work reports a simple and sensitive on-line solid-phase extraction system for the pre-concentration and determination of a trace amount of Co(II (ions by flame atomic absorption spectrometry (FAAS). This method is based on the on-line retention of cobalt ions with polyvinyl chloride modified by 3-(2-thiazolylazo)-2,6-diaminopyridine (TADAP) in a mini-column system. The retained Co(II) ions were eluted with 1.0 mol L-1 HCl, and direct aspiration to flame atomic absorption spectrometry (FAAS) for an accurate determination of it. The important experimental parameters such as the solution pH, length of column (adsorbent mass), sample flow rate, solvent eluent, type and concentration of the eluent, and co-existing ion effects were investigated in detail and optimized. Under the optimum conditions, the calibration graph was linear over the concentration range of 2-150 µg L-1 for pre-concentration of 10.0 mL of the sample solution. The interassay precession (n = 6) was in the range of 1.8-5.2% at the concentration levels of 10.0, 50.0, 100.0, and 140.0 µg L-1. The limit of detection and enrichment factor were 1.3 µg L-1 and 40, respectively. The method was applied for determination of trace levels of Co(II) ions in different real samples such as tap water, waste water, vegetable, fruit, and drug with satisfactory results.

Here, a simple/efficient analytical strategy based on dispersive solid phase extraction was developed using CoSn(OH)6 nanocubes for lead ions from environmental water samples by FAAS (flame atomic absorption spectrometry). CoSn(OH)6 was synthesized as an adsorbent using the co‐precipitation method and characterized. The characterization studies proved the cube‐shaped morphology and uniform size distribution. The optimal experimental conditions were found by optimization studies and, the limit of quantification (LOQ), limit of detection (LOD), linear dynamic range were recorded as 37.6 μg/L, 11.3 μg/L, and 40–600 μg/L, respectively. The enhancement factor of the presented method was calculated as 158.7‐folds compared to the LOD of the conventional FAAS system. Recovery experiments were performed to check the method's applicability/accuracy and the percent recovery results varied from 89.0 % to 112.9 %. According to these findings, the developed method was successfully applied for the quantitative determination of the target analyte in a seawater sample matrix.
