Polysulfone (PSF) microcapsules containing ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim][PF6]) as extractant have been successfully prepared using solvent evaporation method and used in removing caprolactam from water. The results showed that ionic liquid [Bmim][PF6] was successfully encapsulated by PSF and the encapsulation capacity of 32.44% was achieved. Systematic studies...
Individual and competitive adsorption characteristics of Cr(VI) and phosphate (P) onto synthetic Fe–Al hydroxides were investigated. A series of batch experiments were performed to study the influence of various experimental parameters (pH, ionic strength and contact time) on Cr(VI) and P adsorption. Removal efficiency of Cr(VI) and P decreased with increasing pH and ionic strength. In individual...
This study focused on the competitive adsorption of congo red (CR) and copper by chitosan hydrogel beads in a binary adsorption system. Spectroscopic analysis, including Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) were integrated with kinetic studies to elucidate the interaction. It was determined that chitosan hydrogel beads show better adsorption performance...
The objective of this work is to investigate the effects of pH and ionic strength on the adsorption capacity for fulvic acid (FA) by chitosan hydrogel beads. The results indicated that the sorption amount increased with decreasing pH and increasing ionic strength concentration. The sorption isotherms were well described by using non-linear Langmuir, Freundlich and Redliche–Peterson equation. The adsorption...
This paper devotes to synthesize a new-style nano inner-modified aluminum trihydroxide (IMATH) flame retardant by carbonation in a rotating packed bed (RPB) reactor and hydrothermal modification. Sodium aluminate (SA) solution was carbonated in RPB reactor to yield nano aluminum trihydroxide (ATH) gels, which subsequently reacted with oxalic acid at the optimum hydrothermal conditions of 1h and 160°C...
