“…On the contrary, at high initial concentrations of sorbate ions, the degree of sorption decreased due to the saturation of sorption centers. To describe the adsorption process of Fe 2+ the isotherm was analyzed using the Langmuir and Freindlich isotherm models [16,30]. The Langmuir model is valid for monolayer sorption on a surface with a certain number of identical reaction centers and is described by the following equation:…”

In the present work, freshly prepared from urea powders of graphite carbon nitride were subjected to ultrasonic exfoliation and were used to evaluate their adsorption efficiency for iron and copper ions from an aqueous solution. It has been established that the sorption efficiency is significantly affected by the pH of the medium, the contact time, and the initial concentration of metal ions. It is shown that the Fe2+ sorption isotherm by carbon nitride can be well modeled by both the Langmuir and Freundlich adsorption isotherms based on correlation coefficients

“…The most important interpretation of the experimental results obtained from the different used methods and adsorbents were compared with the prepared PVP:AA hydrogel adsorbent. Table 5 shows the comparison between different types of adsorbent materials, reported from previous work [16], [26] and [29][30][31] and those of the synthesized PVP:AA hydrogel sorbent. The reported results concluded that the synthesized green adsorbent has a high adsorption efficiency and capacity than other materials which makes it more sustainable for the removal and trapping of heavy metal ions such Zn, Co and Ni and Mn from aqueous solution.…”

As heavy metals are a group of pollutants that originate from industrial and nuclear facilities has become of major concern in the aquatic environment due to their toxicity to all living organisms. In this context; this study was aimed to prepare sustainable and efficient hydrogel for the removal of heavy metals such as Co, Ni, Zn and Mn from aqueous acidic solution. The polyvinylpyrrolidone (PVP)/abietic acid (AA) hydrogel were prepared by gamma irradiation at 50 kGy. The characterization of PVP/AA hydrogel were investigated by water absorbancy, gel content, scanning electron microscopy, X-ray diffraction (XRD) and Fourier transform infrared (FTIR). The characterizations indicate that bio-sorbent composite hydrogel networks provide advantageous over conventional preparation techniques. PVP/AA hydrogel was implanted for batch process with studying the effect different parameters on the sorption of the investigated metal ions such as radiation dose; pH, contact time, metal ions, V/m and temperature. The results illustrate that the highest uptake% was obtained at radiation dose 30 kGy at optimum pH = 3. The maximum adsorption capacity of PVP-AA adsorbent was reached 32, 32.5,19 and 32.5 mg.g− 1 for Zn(II), Co(III), Ni (III) and Mn(II) ions respectively. The changes in the values of free energy (ΔG) and enthalpy (ΔH) confirm the spontaneous nature of the adsorption reaction with an endothermic process. The maximum desorption of the investigated metal ions was achieved with 1 M HNO3 of (97%, 98%, 70% and 60%) and takes the order: Co > Ni > Zn > Mn. The highest separation factor for Zn/Co = 26 and Zn/Ni = 8.6 at pH = 0.75.
