“…2 The coprecipitation technique is based on the accumulation of metal ions on water-insoluble precipitates of various organic or inorganic characters. 17 In general, in the coprecipitation method two types of reagents are used; i) inorganic coprecipitants such as hydroxides and sulphides [18][19][20][21][22][23] ii) organic coprecipitants such as some chelates or chelating ligands. 1,9 However, in both cases, the carrier element, which is added to the medium in excessive amounts for precipitate formation, may have interference effects during the analysis step.…”

In the present investigation, the application of an organic coprecipitant, 2- [5,6-dichloro-2-(2-bromobenzyl)-1H-benzimidazole-1-yl]acetohydrazide (DIBBA), for separation and preconcentration of Cu(II) ions in fruit and water samples through a new carrier element free coprecipitation (CEFC) method was researched for the first time. Flame atomic absorption spectrometer (FAAS) was utilized for the analyses of Cu(II) ions. The main effective experimental factors such as solution pH, DIBBA quantity, waiting time, centrifuge speed and duration and volume of sample on the recovery efficiency of Cu(II) ions were explored in detail. Under the optimized conditions the preconcentration factor (PF), relative standard deviation (RSD), and limits of detection (LOD) was achieved as 50, 3.4 %, and 0.44 ?g L-1, respectively. No interference effects were detected by virtue of the presence of various foreign ions. Satisfactory recoveries (in the range of 94.4 to 103.0 %) in the environmental sample matrix were acquired. After being validated the recommended selective, low cost, simple and rapid CEFC method by spike/recovery tests, it was featly implemented for the low levels detection of Cu(II) ions in sour cherry, mulberry, apple, and peach as fruit samples and stream and sea water samples without any significant matrix effects.

“…Enrichment and separation techniques are required to analyze Co(II) and Ni(II) at trace levels due to low metal concentrations and matrix interferences in actual samples. Several enrichment procedures have been developed for the determination of Co(II) and Ni(II), involving various analytical techniques such as coprecipitation [13][14][15][16][17][18][19], liquid-liquid microextraction [20][21][22][23][24][25], cloud point extraction [26][27][28][29][30][31], membrane filtration [32,33], and solid-phase extraction [34][35][36][37][38][39][40][41].…”

Prior to FAAS determination, a green, simple, and validated ultrasound-assisted ionic liquidbased dispersive liquid-liquid microextraction technique (UA-IL-DLLME) was developed for preconcentration and separation of cobalt (Co(II)) and nickel (Ni(II)) ions in various environmental and biological samples. The suggested method uses an ionic liquid (IL) (1-hexyl-3-methylimidazolium tris(pentafluoroethyl)trifluorophosphate [HMIM][FAP]) as an extraction solvent for Co(II) and Ni(II) ions following complexation with 3-(2-hydroxy-5methyl-1-ylazo)-1,2,4-triazole (HMAT) at pH 8. The effects of several analytical factors on microextraction performance were examined. Under ideal conditions, the calibration curves were linear in the ranges of 1-400 and 1-300 μg L −1 , with limits of detection of 0.30 and 0.28 μg L −1 for Co(II) and Ni(II), respectively. The preconcentration factor was 100. The analyte recovery rates ranged from 96to 102 percent. Furthermore, for Co(II) and Ni(II), the relative standard deviation (RSD%) for intra-day (1.20 and 1.50%) and inter-day (1.60 and 1.80%) as precision, respectively. The proposed preconcentration approach was tested using certified reference materials (SRM 1570A spinach leaves and TMDA-52.3 fortified water). The suggested UA-IL-DLLME method was successfully used to preconcentrate and determine the concentration of Co(II) and Ni(II) ions in a variety of real environmental (water, juice, and food) and biological (hair) samples, producing satisfactory results.

It has advantages such as simplicity, low consumption of reagents, and high preconcentration factor, which are essential in the determination of trace elements (Moreira et al 2020). In addition, multiple analytes can be separated and pre-concentrated in a single matrix step using different organic or inorganic precipitants Tuzen and Soylak 2009; Chen et al 2016).…”

Multivariate optimization is remarkable in establishing preconcentration methods as it analyzes the involved factors' interactions(Silva et al 2020;Moreira et al 2020).

A Box-Behnken design approach was used to plan the experiments for As and Cd determination in fish samples. It combines microwave-induced plasma optical emission spectrometry (MIP OES) with silver nitrate and potassium chromate coprecipitation. Multiple Response methodology (MR) has been adopted to express the output parameters (responses) that are decided by the input process parameters. MR also quantifies the relationship between the variable input parameters and the corresponding output parameters. Factors that directly affect the coprecipitation procedure, such as silver and chromate concentrations and solvent volume, were optimized. The optimized conditions were 5.46 x10− 4 mol L− 1 [CrO42−] and 1.16 x10− 3 [Ag+], without needed of solvent addition. The procedure provided preconcentration factors of 25 and 11 for As and Cd, respectively, and LOD adequate to the international legislation. The trueness was assessed with the analysis of certified reference materials (CRMs) and compared with inductively coupled plasma mass spectrometry (ICP-MS). Relative standard deviations < 9% and 3.5% and recoveries > 91% and 88% were obtained for As and Cd, respectively. The method was applied to local market fish samples and showed suitability for As and Cd determination by MIP OES.
