“…This phenomenon can be due to the transfer and removal of protons on the available functional groups on the outer part of the adsorbent under various pH conditions, as well as the anionic and cationic nature of the target dye ( Kanani-jazi & Akbari, 2021 ). The zeta potential (pH pzc ) of the OLPAC was found to be 2.5, these denote that the surface charge of the adsorbent stays positive below the pH pzc and negative at pH above this value ( Akawa et al., 2021a ; Biata et al., 2018 ). So, because the OLPAC surfaces are positively charged at low pH, strong electrostatic interactions occurred between the adsorbent and the anionic MO, resulting in maximum removal efficiency.…”

“…Additionally, a value control of sandy loamy mud was employed to ensure the technique's effectiveness. Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-OES) is a well-known analytical technique that has a wide linear dynamic range, the limit of detection, high precision, and accuracy (Biata et al 2018). It can be used to quickly and easily determine the major, minor, and trace elements in river water and also widely used to determine heavy metal contents in water.…”

Water quality for the surface water along the Kunhar River in the Mansehra district, Pakistan, was assessed for 10 water sample stations. A variety of parameters indicating water quality including physicochemical parameters, nutrients, heavy metals, and antibiotic residues were measured for both the rainy and dry seasons, the two main tropical seasons in Mansehra using the standard methods. The Kunhar River, one of the local drinking water sources, was studied to assess the heavy metal content, health risk assessment, and its suitability for human consumption. Eleven heavy metals (such as As, Cd, Co, Cr, Cu, Fe, Hg, Na, Se, Pb, and Zn) in water were investigated from the Kunhar River basin. Heavy metals evaluated exceeded standards and warranted risk assessment. Concentrations of metals in water have a decreasing trend in water indicating that the accumulation of metals can affect the water chemistry of aquatic systems due to any physical or chemical process in the system. Greater consideration should be given to the variety of metals in relationship to multivariate analyses suggesting that the industrial and residential activities were more important contributors to the pollution of the Kunhar River than the agricultural activities in the Mansehra district and the risks faced by aquatic life due to the presence of such metals.

“…Among the aforementioned techniques, ICP-OES is one of the most widely used detection method 11 . This is because ICP-OES is robust and can be applied for the qualitative and qualitative analysis of multielement in complex matrices 12 , 13 . Therefore, owing to the low concentration of trace metals in various samples and the complexity of the sample matrices, there is a need for separation/preconcentration methods before ICP-OES determination.…”

“…Design and choice of adsorbents in solid-phase based sample preparation techniques plays a most important factor to get a good recovery and high selectivity 13 . Among other adsorbents reported in the literature, nanomaterials have found great attention in recent years due to their high surface area and large adsorption area 22 .…”

A magnetic Fe3O4@MgAl-layered double hydroxide (MLDH) nanocomposite was successfully synthesized and applied as an effective adsorbent for preconcentration of trace As(III), Cd(II), Cr(III), Co(II), Ni(II), and Pb(II) ions from complex matrices. The quantification of the analytes was achieved using the inductively coupled plasma optical emission spectrometry (ICP-OES) technique. The nanocomposite was then characterized using BET, FTIR, SEM, and EDS. Due to its high adsorption surface area, compared to traditional metal oxide-based adsorbents, MLDH nanocomposite exhibited high extraction efficiency. Several experimental parameters controlling the preconcentration of the trace metals were optimized using response surface methodology based on central composite design. Under optimum conditions, the linearity ranged from 0.1 to 500 µg L−1 and the correlation of coefficients (R2) were higher than 0.999. The limits of detection (LODs) and quantification (LOQs) were 0.11–0.22 µg L−1 and 0.35–0.73 µg L−1, respectively. The intra-day (n = 10) and inter-day precisions (n = 5 working days) expressed in the form of percent relative standard deviations (%RSDs) were below 5%. The proposed method was successfully applied for the analysis of the As(III), Cd(II), Cr(III), Co(II), Ni(II), and Pb(II) ions in different environmental water samples.
