The possible use of activated alumina powder (AAP) as adsorbent for Cr(III), Ni(II), and Cu(II) from synthetic solutions was investigated. The effect of various parameters on batch adsorption process such as pH, contact time, adsorbent dosage, particle size, temperature, and initial metal ions concentration were studied to optimize the conditions for maximum metal ion removal. Both higher (molar) and lower (ppm) initial metal ion concentration sets were subjected to adsorption on AAP. Adsorption process revealed that equilibrium was established in 50 min for Cr(III) at pH 4.70, 80 min for Ni(II) at pH 7.00, and 40 min for Cu(II) at pH 3.02. Percentage removal was found to be highest at 558C for Cr(III) and Ni(II) with 420 mm and 458C for Cu(II) with 250-mm particle size AAP. A dosage of 2 g for Cr(III), 8 g for Ni(II), and 10 g Cu(II) gave promising data in the metal ion removal. The adsorption process followed Langmuir as well as Freundlich models. The thermodynamics of adsorption of these metal ions on activated aluminum indicated that the adsorption was spontaneous and endothermic in nature. Present study indicates that AAP can act as a promising adsorbent for industrial wastewater treatment.

“…Due to the high complexity of the matrixes and the low level of cobalt ions in the aquatic samples, separation, and preconcentration step prior to cobalt analysis are needed 13, 14. There are many methods for preconcentration such as, coprecipitation, solvent extraction, electrochemical deposition, membrane extraction, and solid‐phase extraction 15–17. Solid‐phase extraction (SPE) has become a preferred method at enrichment of many metal ions prior to their analysis by FAAS and other techniques.…”

In this study, a new solid-phase extraction procedure has been developed for preconcentration and determination of Co ions in different water samples by flame atomic absorption spectrometry (FAAS). Cobalt was preconcentrated as N,N 0 -bis(pyridine-2-ylmethyl)benzene-1,4-diamine (Co-BPMBDA) from sample solutions using a column containing Amberlite XAD-7 and was determined. In order to achieve the best performance for the method, effects of several parameters such as pH, concentrations of ligand, sample flow rate, eluent, and matrix ions on the method efficiency were investigated. Under optimum conditions, the preconcentration factor was found to be 200 for 1000 mL waters samples. Detection limit based on the 3S b criterion was calculated as 0.24 mg/L for 100 mL of sample solution and relative standard deviation was found to be 1.8%. The method was applied to determine the trace amounts of cobalt in water samples.Keywords: Amberlite XAD-7; Cobalt; Preconcentration; FAAS; Solid-phase extraction IntroductionCobalt is an important element for industry and for biological systems. Cobalt is present in vitamin B 12 and is an essential micronutrient for all living systems [1]. Drinking water, food, and inhalation are common ways of cobalt contamination for living organisms. The deficiency of cobalt in human and animal bodies results in anemia [2], while large amounts of cobalt causes to toxic effects (mechanism to fail in asthma, kidney and liver disorders, heart growth and expansion, sinus tachycardia), usually after occupational exposure to cobalt dust (cobalturia, cobaltemia) [3, 4]. There are two main alternative sources of cobalt for aquatic environment: Natural sources and anthropogenic sources. The natural sources include volcanic emissions, the weathering of rocks by the action of water and decomposition of plant waste. The main human-related sources of cobalt to aquatic environment are sewage and industrial waste [5].Since one of the routes of incorporation of cobalt into the human body is by ingestion, its determination in drinking water, food, and environmental samples such as soil and dust becomes very important [6].Several analytical techniques including electrothermal atomic absorption spectrometry (ETAAS) [7], inductively coupled plasma optical emission spectrometry (ICP-OES) [8], inductively coupled plasma mass spectrometry (ICP-MS) [9], flame atomic absorption spectrometry (FAAS) [10], and high performance liquid chromatography (HPLC) [11,12] have been devised for the determination of cobalt in different matrixes.Due to the high complexity of the matrixes and the low level of cobalt ions in the aquatic samples, separation, and preconcentration step prior to cobalt analysis are needed [13,14]. There are many methods for preconcentration such as, coprecipitation, solvent extraction, electrochemical deposition, membrane extraction, and solid-phase extraction [15][16][17].

“…Compared with the traditional methods used to remove Ni(II) from solutions including chemical coagulation and precipitation, ion exchange and adsorption, solvent extraction, biosorption and electrocoagulation, the membrane separation techniques have become increasingly attractive for the disposal of Ni(II), due to the advantages of time-saving, lower pressure drop and shorter axial-diffusion path [4,5]. However, in comparison with the conventional exchange resin adsorption process, the membrane techniques applied to remove Ni(II) involving electrodialysis [6], liquid membrane extraction [7], polymer-enhanced filtration [8,9], nanofiltration, and reverse osmosis [10,11] have been restricted to a certain extent because of the higher costs or the more fussy pretreatments.…”

He (2015) Adsorption performance of APTMS-DTPA/PVDF chelating membrane toward Ni(II) with the presence of Ca(II), NH 4 + , lactic acid, and citric acid, Desalination and Water Treatment, 53:1, 158-170, A B S T R A C TThe 3-aminopropyltrimethoxysilane-diethylenetriaminepentaacetic acid/polyvinylidene fluoride (APTMS-DTPA/PVDF) chelating membrane was prepared to remove Ni(II) from the solutions. The adsorption performance of the membrane toward Ni(II) was investigated by the adsorption experiments and density functional theory (DFT) calculations, considering the existence of Ca(II), NH þ 4 , lactic acid, and citric acid. Ca(II) tended to form more stable complex with the APTMS-DTPA ligand of the chelating membrane than NH þ 4 . Citric acid showed a larger interference on Ni(II) uptake than lactic acid. Lagergren second-order equation and Langmuir model were competent for descriptions of the adsorption kinetics and the isotherms, respectively. The negative DG˚and DH˚indicated the spontaneous and exothermic nature of Ni(II) adsorption. The results of DFT calculations were consistent with the experimental data. The complexing sequences of the metal ions with the APTMS-DTPA ligand were in the order of NH þ 4 < Ca(II) < Ni(II). The stabilities of the Ni(II)-organic complexes followed the order of Ni(II)-lactic acid < Ni(II)-citric acid < Ni(II)-(APTMS-DTPA). Therefore, the complexation between Ni(II) and APTMS-DTPA ligand of the membrane was prominent.
