“…This pollution is mainly associated with many anthropogenic activities (e.g., urbanization, development in agriculture and industry). Therefore, there is an urgent need to address the safety problems caused by this pollution (Elbana et al 2019). Furthermore, soil pollution is considered a one of the most significant current discussions in legal and moral philosophy.…”

S TRESSED environments have long been a question of great interest in a wide range of fields. So, many considerable literatures have grown up around this theme. In Egypt, there are several common problems related to the stressed environments. These stresses include decline of soil fertility, soil salinity and alkalinity, soil water logging, salt-affected soils, soil pollution, climate change, overpopulation growth, urban sprawl, land degradation, deterioration of natural resources, etc. More generally, national income will decline and will in turn result in the spread of social and political problems. Kafr El-Sheikh governorate can be considered one of the most important areas in Egypt, which calls "the governorate of the hope and the future" due to its location and wealths. Whereas, this governorate suffers from the most common stresses in Egypt including pollution, salinity, alkalinity and waterlogging. Great problems have been recorded in Kafr El-Sheikh related to stressed environments and suggested solutions also have been addressed. Therefore, a sustainable management should be adapted for overcoming these stressed environments in Kafr El-Sheikh.

“…Results of maximum sorption capacities for Pb on the alkaline soils after 1-day ranged from 7.7 mmol kg −1 (Morey) to 36.0 mmol kg −1 (Houston), whereas most applied Pb was sorbed after 7-days. Elbana et al [8] reported that Pb exhibited the highest nonlinear sorption on several Egyptian calcareous soils compared with Cu, Zn, Cd, and Ni. Our results of Pb-maximum sorption capacities in the acidic soils extended from 6.4 mmol kg −1 (Candor-subsurface) to 36.5 mmol kg −1 (Arapahoe).…”

“…The reactivities of Cu and Pb depend on various soil characteristics such as pH, cation exchange capacity (CEC), and soil contents of clay minerals, carbonates, oxides, and organic matter (OM). In addition to soil properties, environmental soil conditions, as well as physiochemical characteristics of the trace elements control the fate and behavior in soils [7,8]. Accurate prediction of Cu and Pb sorption/desorption in soils requires evaluation of numerous experimental data that are derived from various soils.…”

Batch kinetic experiments were carried out to quantify and describe the sorption/desorption of Cu and Pb in ten soils that exhibited a wide range of properties. Sorption isotherms were quantified using the Langmuir equation, whereas modeling of sorption/desorption kinetics was described using multireaction model (MRM). Results revealed the nonlinear sorption behavior of Cu and Pb in all soils. The ten soils exhibited higher affinity to Pb (6.4 to 36.5 mmol kg−1) in comparison to Cu (3.6 to 22.4 mmol kg−1). Simulation of Cu and Pb kinetic data indicated that the rate of sorption reaction was two orders of magnitude higher than the rate of release. Considering one irreversible site in addition to one-reversible kinetic site improved the estimation of rates of reaction for both Cu and Pb in acidic and alkaline soils. All soils exhibited sorption/desorption hysteresis where Pb-releases ranged between <0.2% and 14.4% of the total sorbed. The respective Cu releases ranged from <0.85% and 23.4%. The multireaction model, which was successful in describing Cu and Pb for all ten soils, provided insight into the processes of sorption/desorption of Cu and Pb in all soils.

Developing a highly selective method for preconcentration and determination of cobalt in water and nut samples using 1‐(2‐pyridylazo)‐2‐naphthol and UV–visible spectroscopy

BACKGROUND Heavy metal contamination in water and agricultural products is a major concern that causes risks for human health. This article describes a highly selective approach to preconcentrate cobalt(II) (Co(II)) ions based on the standard UV–visible measurement of Co(II)–1‐(2‐pyridylazo)‐2‐naphthol complex at λ = 628 nm in water and nut samples. In this method, magnetic silica (mSiO2) was utilized as a practical sorbent and 1‐(2‐pyridylazo)‐2‐naphthol was employed as a complexing agent in the elution step. The adsorbent was characterized via X‐ray diffraction spectroscopy, Fourier transform infrared spectroscopy, and scanning electron microscopy. The effects of the main variables (pH, adsorption time, sorbent amount, pH of eluent, ligand volume, and desorption time) were investigated and established. RESULTS The maximum recovery was achieved at pH 7 ± 0.3, adsorption time of 60 min, sorbent amount of 40 mg, eluent pH 8 ± 0.2, ligand volume of 2 mL (16.95 × 10−4 mol L−1) and desorption time of 30 min. The linearity of dynamic range (10–500 μg L−1), limit of detection (0.32 μg L−1), relative standard deviation (3.04%), and preconcentration factor (25) show the reliability of the method. The sorbent was reusable 12 times. Selectivity and the effect of interference ions were successfully examined. The adsorption process of Co(II) ions on mSiO2 was investigated based on Langmuir and Freundlich isotherms. The Freundlich model was fitted with the system and the maximum capacity adsorption of mSiO2 for Co(II) adsorption is 2.35 mg g−1. Then, the kinetics study revealed that the adsorption process of Co(II) ions on the mSiO2 follows the pseudo‐first‐order model. The thermodynamics parameters ΔG, ΔS, and ΔH were calculated. CONCLUSION The method was fruitfully applied to preconcentrate Co(II) ions in water and nut samples. This method offers high selectivity and precision for determining Co(II) ions. © 2020 Society of Chemical Industry
