“…In the case of Co, an adsorption with apatites of 8.8-20 mg/g has been reported, a value lower than that obtained with natural nDCPD obtained in the present study, which is 41.8 mg/g. Finally, in the case of Cu ions, a range of adsorption has been documented in this type of materials of 26.6-343.64 mg/g, a value comparable to that obtained in the present work with nDCPD [7,15,[32][33][34][35].…”

“…The contamination of water bodies due to the presence of heavy metals is a serious problem, because every day this vital resource is scarce and because of the high toxicity of these compounds for the health of living beings. The metals present in water are a risk factor for the development of diseases such as cancer and dermatitis; in addition, they may be accumulated in the human body because they cannot be metabolized [1][2][3][4][5][6][7]. Solid-liquid removal processes such as chemical precipitation, filtration, and adsorption, among others, have been widely used for the removal of metals such as nickel (Ni), iron (Fe), copper (Cu), zinc (Zn), cobalt (Co), and chromium (Cr) of liquid effluents [8][9][10][11]; however, some of these methods have disadvantages such as high operating cost and low efficiency; however, methods such as coagulation and precipitation are already used in various industrial processes for the removal of metals from industrial effluents [12].…”

Recently the interest in the remediation of liquid effluents from industries such as paint manufacturing, leather tanning, etc. has increased, because the quality of the water used in these processes is highly compromised and is generally discarded without any process of purification, causing an inadequate use of water and contributing to the hydric stress of the planet. Therefore, it is necessary to find alternatives for the remediation of water used in industrial processes; one of the methods that has been widely accepted given its high efficiency, low cost, and versatility compared to others is the bioadsorption using materials derived from various processes used for the elimination of metals such as Cr, Co, Cu, Ni, etc. from liquid effluents. Among the materials used for this purpose are rice husk, orange, and wheat as well as apatite (hydroxyapatite and brushite), derived from animal bones, which have shown good capacity (>90%) to adsorb metals from aqueous solutions. Through the characterization by DRX, FTIR, and SEM, of the brushite and studies in equilibrium and kinetics of adsorption, it has been demonstrated that this material has a good capacity to remove metals present in water.

“…Extreme toxicity of heavy metals and their adverse effects on the environment has engendered enormous necessity to develop selective, low cost, cheap and fast methods to detect them . Among these heavy metals we find chromium, on one hand, trivalent chromium is an essential element for human health, and its insufficiency increases the risk factors associated with diabetes and cardiovascular diseases .…”

Comparison between Modified and Unmodified Carbon Paste Electrodes for Hexavalent Chromium Determination

et al. 2018

This work consists of developing a simple electroanalytical method which allows the speciation of Cr(VI). Gold modified Carbon Paste Electrodes (CPEs) and unmodified CPEs have been tested for the determination of Cr(VI) in presence of an excess of Cr(III) by using differential pulse voltammetry (DPV), without any accumulation or pre‐concentration time. Several parameters affecting the analytical performances of the designed electrodes were investigated, including: electrodeposition technique of AuNPs onto the CPE, amount of AuNPs dropped on the electrode surface, supporting electrolyte, presence of Cr(III), presence of chloride ions and concentration of diphenylcarbazide (DPC). Under the optimal conditions, the use of unmodified CPE in an acidic medium containing DPC exhibited a high selectivity and a good detection limit of 19 μg ⋅ L−1, which is much lower than the admissible concentration fixed by the World Health Organization (50 μg ⋅ L−1). A linear range from 50 to 260 μg ⋅ L−1 was obtained with a relative standard deviation of 7.75 %. Furthermore, as opposed to the AuNPs‐modified CPE, the current response of Cr(VI) obtained at the unmodified CPE was not affected by the presence of chloride ions and trivalent chromium. Finally, the proposed method was successfully applied for the determination of Cr(VI) in real tap water samples with satisfactory results.

“…Therefore, a rapid and precise analytical method for the determination of nickel is essentially required for the production control of spoolable reinforced plastic line pipe. Numerous analytical methods were employed for the determination of nickel in different types of matrices including atomic absorption spectrometry [2,3], atomic emission spectrophotometry [4], molecular fluorescence spectroscopy [5], electroanalytical method [6] and spectrophotometry [7,8]. Spectrophotometric methods occupy special position due to their simplicity, less expensive instrumentation and high sensitivity.…”

Abstract. Spoolable reinforced plastic line pipe will be widely used in the exploitation of acid gas and oil wells. End-fitting is a mechanical device that forms the transition from the spoolable reinforced plastic line pipe to the connector. It was well known that nickel was an important element in the end-fitting. In this paper, a novel spectrophotometric method was described for determination of nickel in the end-fitting of spoolable reinforced plastic line pipe. The method was based on the color reaction between nickel and dimethylglyoxime, which was favored in an alkaline medium, producing a red compound in the presence of ammonium persulfate as an oxidant. Under the optimum reaction conditions the absorption value was proportional to the concentration of nickel in the range of 0.080~0.50% (R2 = 0.9999), and the relative standard deviation was less than 3.0% (n=5). The proposed method was applied successfully to determine nickel in end-fitting of spoolable reinforced plastic line pipe.
