“…This can be demonstrated by a high linear correlation coefficient R 2 =0.9908. This also proved that the sorption of oil on the grafted fibers was monolayer sorption [53,54]. From the obtained equation (Figure 10), we can identify the maximum oil sorption capacity is Q max =1/0.048=20.833 (g/g).…”

“…The obtained data imply that sorption of PAEs molecules by the PP-g-(AA+BMA) is a monolayer type and PAEs molecules from the aqueous solution usually form a layer on the surface of the grafted fiber substrate. The fact implies that the sorption of PP-g-(AA +BMA) for trace PAEs from water is complex, involving more than one mechanism [23].…”

2014) Phthalate esters removal using modified fiber prepared by two-step electron beam irradiation of methacrylate monomer onto polypropylene substrate, Desalination and Water Treatment, 52:28-30, 5470-5478, A B S T R A C TA novel modified polypropylene-methacrylate fiber (PP-g-(AA+BMA)) was prepared by grafting acrylic acid (AA) and butyl methacrylate (BMA) onto the polypropylene (PP) fiber substrate using a two-step electron beam irradiation method. It was used as a sorbent to recover high concentrations of phthalate esters (PAEs) from water. AA was first grafted onto PP substrate by electron beam, and then the pretreated PP was soaked into BMA solution and the loaded monomer was grafted on the PP substrate by electron beam induced. Fourier transform infrared spectra and contact angle (CA) were employed to characterize the chemical changes of PP substrate. In addition, the effect of the first and the second reactions on the degree of grafting was studied. The results indicated that the PP-g-(AA+BMA) could successfully be used to remove PAEs from water, leading to superior improvement of environmental preservation.

“…In this mechanism, the In(III) ions with empty orbitals function as a Lewis acid capable of accepting electron pairs. In contrast, the sulfonic acid groups that have non-shared electron pairs function as Lewis bases, donating their electrons pairs [22].…”

This work assesses the potential of an adsorptive material, Dowex 50w-x8, for the separation of indium ions from cadmium ions in aqueous media. The adsorption behavior of Dowex 50 w-x8 for indium and cadmium ions was investigated. The effect of pH, initial concentration of metal ions, the weight of resins, and contact time on the sorption of each of the metal ions were determined. It was found that the adsorption percentage of the indium ions was more than 99% at pH 4.0. The result shows that In (III) was most strongly extracted, while Cd(II) was slightly extracted at this pH value. The recovery of In(III) and Cd(II) ions is around 98% using hydrochloric acid as the best eluent.
