“…Generally, most peaks in PVP K60 are reserved in PF-2.2, PF45, PF60, and PF75, and they may merge with the peaks of other chemical structures. Moreover, unique peaks of raw resole and cured resole are recorded in the spectra, which are analyzed in Table . ,− First, preoxidation leads to the cure of resole. In this process, the diameters of the fibers shrink by ∼10%, and the cured fibers turn yellow and tenacious.…”

The adsorption of volatile organic compounds (VOCs) on phenolic-based carbon fibers is a current research hotspot. However, research on the inner association between preoxidation, carbonization, and adsorption performance is insufficient. This work studied the electrospinning, preoxidation, and carbonization conditions of thermosetting phenolic resin and the relevant effects on the VOC adsorption performance of derived activated carbon fibers. The static and dynamic adsorption performances of benzene over four types of carbon fibers were tested, and oxygenated VOCs (OVOCs) were introduced for binary VOC competitive adsorption tests. The results indicate that a proper amount of auxiliary agent promises continuous fibers and chemically associates with resole during electrospinning and preoxidation. Moreover, a proper curing time and high carbonizing temperature endow carbon fibers with a high surface area and excellent adsorption performance. Finally, the small-sized basal planes and amorphous sp 2 clusters readily adsorb benzene with the strong π−π interaction, which essentially determines the competition performance between OVOCs and benzene.

“…It can be seen from Figure 2 that the characteristic peaks of MIL-101(Fe) included carboxyl groups (1658 cm −1 , 1593 cm −1 and 1388 cm −1 ), benzene groups (1498 cm −1 ), and chelate bonds formed by Fe 3+ with carboxyl groups (553 cm −1 and 748 cm −1 ) [ 47 , 52 ], proving the successful preparation of MIL-101(Fe). Moreover, the characteristic peaks of sodium metasilica included Si-O-Si stretching vibrations (1022 cm −1 , 707 cm −1 and 587 cm −1 ) [ 53 , 54 ], indicating that silicic acid could be adsorbed on the surface of MIL-101(Fe).…”

Reverse osmosis (RO) membranes are susceptible to silica scaling, resulting in irreversible degradation of membrane performance. This work covered the fabrication of MIL-101(Fe) for silicic acid adsorption to alleviate the silica scaling of RO membranes. The effect of pH, mixing time and initial concentration on silicic acid adsorption of MIL-101(Fe) was appraised in detail. The adsorption experiments demonstrated that MIL-101(Fe) possessed an excellent adsorption ability for silicic acid with the maximum adsorption capacity reaching 220.1 mgSiO2·g−1. Data fitting confirmed the pseudo-second-order equation and Freundlich equation were consistent with silicic acid adsorption on MIL-101(Fe). Finally, a simulated anti-scaling experiment was carried out using a feed solution pretreated by MIL-101(Fe) adsorption, and the permeance exhibited a much lower decline after 24 h filtration, confirming that MIL-101(Fe) exhibits an excellent application potential for silica-scale mitigation in RO systems.
