“…This behavior is reasonably approximated by an instantaneous equilibrium [42]. It can be explained on the basis that initially there is a rapid reversible sorption of the solute adhering to accessible sites on the soil surface [43].…”

Pakistan occupies a significant global position in the growing of high quality cotton. The extensive application of pesticides on agricultural products leads to environmental risk due to toxic residues in air, water and soil. This study examined the chemodynamic effect of Deltamethrin on cotton fields. Samples were collected from the cotton fields of D.G. Khan, Pakistan and analyzed for heavy metal speciation patterns. Batch experiments were administered in order to study the adsorption of Deltamethrin in cotton fields. The effect of different factors including pH, adsorbate dose, and adsorbent mass on adsorption were studied. It was observed that in general, adsorption increased with increases in the mass of adsorbate, although the trends were irregular. Residual fractions of deltamethrin in the soil and water of cotton fields were analyzed to assess concentrations of xenobiotics bound to soil particles. Results indicated that such residues are significantly higher in soil samples due to high Koc in comparison to water, indicating the former is an efficient degradation agent. Results from the batch experiment resulted in 95% removal with alkaline pH and an adsorbent-adsorbate ratio of 250:1. These results may be used to environment friendly resource management policies.

“…Therefore, its recovery from industrial wastewater by using different methods is much studied. Traditional treatment methods have been used to remove organic pollutants such as: adsorption on activated carbons and zeolites, as well as, disinfection by-products [14][15][16]. MB adsorption have been evaluated by using clays minerals, zeolites, red mud, graphene, among others materials [17][18][19].…”

Two composites based on a Zn 2+ exchanged natural clinoptilolite and ZnO nanoparticles were obtained by mechanosynthesis and 'in situ' methods. Characterization of resulting materials was carried out using XRD, Raman spectroscopy, TGA, FE-SEM and N 2 adsorption. XRD results showed that no significant changes in the crystalline structure of the zeolite took place due to the performed treatments. Thermogravimetric behaviour indicated a high thermal stability for all samples. Raman spectra exhibited the characteristic bands for clinoptilolite zeolite and ZnO reported in the literature and the RRUFF database. Morphology changes were observed between natural and exchanged clinoptilolite and the 'in situ' obtained composite. Textural analysis showed a decrease in surface area of 'in situ' composite compared with the exchanged zeolites, related to the partial nanoparticle deposition in the pore entrances. The adsorption studies of methylene blue in the zeolitic samples and composites showed that all evaluated materials were able to absorb the dye from aqueous solutions.

“…This claim has catalyzed discoveries of various porous carbon materials for wastewater remediation. The use of porous carbon materials such as activated carbon (AC) prepared from various agricultural waste materials [67,68], biochar [69,70], carbon nanotubes (CNTs) [71,72], and other derived carbon materials for the adsorption of PAHs have been studied.…”
