“…Naturally, temperature increases the kinetic energy of the ions and molecules in solution, which has an adverse effect on the adsorption. Similar accounts were given by Matouq et al (2015) for the sorption of nickel onto moringa pods, and by Hannachi et al (2014) for the adsorption of nitrate ions onto a membrane. …”

This work investigates the comparative adsorptive removal of Ni (II) ions from aqueous solution using coconut shell and banana peel. Optimum conditions for adsorption were determined by experimental design, while Analysis of Variance (ANOVA) and BonferroniHolm Posthoc significance statistical tests on operational parameters were also conducted. The parametric effect of adsorbate dose, adsorbent dose, pH, contact time, particle size and temperature were varied individually, and their effect on the percentage of Ni (II) ion removal was estimated. The maximum percentage removal was achieved at a pH of 8.0 by both adsorbents. The optimum conditions obtained for both adsorbents were 4.5 g adsorbent dose, 30 min contact time and 25 o C for coconut shell, and 4.5 g adsorbent dose, 120 mins and 25 o C for banana peel. The Langmuir isotherm best described the adsorption, with correlation coefficient (R 2 ) values of 0.9821 and 0.9744 for banana peel and coconut shell respectively. The mean free energy from the Dubinin-Radushkevich isotherm suggested chemisorption, and the adsorption mechanism was found to fit the second order.

In this paper, characteristics of the interaction of an anion-exchange resin PPE-1 formed using phosphonic acid and granular polyvinyl chloride were investigated. In addition, a reaction order of 1.43 and an activation energy of 47.8 kJ/mol for phosphorylation were determined. The as-obtained polyampholyte was characterized by scanning electron microscopy (SEM), energydispersive X-ray (EDX) analysis, and Fourier transform infrared (FTIR) spectroscopy. Optimum conditions for obtaining a new polyampholyte that selectively adsorbs non-ferrous metal ions on the basis of granulated polyvinyl chloride were determined. Sorption isotherms for non-ferrous metal ions were constructed, which were reasonably explained by Langmuir isotherms. Various thermodynamic parameters, such as isobaric-isothermal potential (ΔG), enthalpy (ΔH), and entropy (ΔS), were calculated to understand the nature of sorption. The examined polyampholyte selectively absorbed copper(II) ions.

“…Biological techniques include thermophilic nitrification-denitrification [10], ion exchange membrane bioreactor [11] and microbial denitrification [12]. A simple, cost effective and easily implemented adsorption method should be selected to achieve significant efficiency in the uptake of ions and remove secondary pollutants [13]. Adsorption through ion exchange is an efficient method of removing several oxyanions because adsorbents can be regenerated and reused [14].…”

The exceedance of nitrate and nitrite concentrations over the water standard quality has caused potential human health dangers such as blue baby syndrome and the growth of aquatic plants (eutrophication). In this work, a Purolite A400 anion exchange resin impregnated by Cu (Purolite A400-Cu) is used to remove nitrate and nitrite in wastewater. High saturation capacities of 0.76 mg N/g and 0.88 mg N/g-nitrate and 0.10 mg N/g and 0.11 mg N/g-nitrite are obtained from Purolite A400 and Purolite A400-Cu. Scanning electron microscope measurement shows that the surface of Purolite A400-Cu is rough due to other deposited materials that originate from Cu deposition. Energy dispersive spectroscopy measurement indicates that the increase in adsorption is due to Cu impregnation with the addition of a positive surface charge on the resin by Cu. The adsorption capacities of nitrate and nitrite decrease with increases in sulphate, phosphate and chloride concentrations. Data are obtained from a fixedbed column using the Thomas equation model. The breakthrough curve shows the C t /C 0 ratio values in Purolite A400 and Purolite A400-Cu. Large C t /C 0 values of 0.55 and 0.52-nitrate and 0.48 and 0.03-nitrite are obtained from Purolite A400 and Purolite A400-Cu.
