Multifunctional polymers with interpenetrating structures: luminescence sensing, ECL behaviors, selective detection of Fe³⁺ ion and rapid removal of anionic dyes

Abstract

Three unprecedented metal–organic frameworks with interspersed structures have been synthesized and structurally characterized.

Selective Adsorption and Removal of Congo Red Based on Ethylenediamine Functionalized Mesoporous Silica

“…Therefore, dye wastewater must be effectively treated before it is discharged into the environment [5–7] . Among various treatment techniques, adsorption is regarded as one of the most effective methods due to its low cost and mild operating conditions [8–12] . Different adsorbents such as activated carbon, modified clay, and MOFs have been applied for the removal of dyes, [13–18] and great progresses have been achieved in the adsorption of dyes from wastewater [19–23] .…”

“…Recently, modified porous materials were used for adsorption studies. Since the first discovery of mesoporous materials in 1990, they have been used in catalysis, sensing, adsorption, and separation [9–10,31–41] . Among them, functional mesoporous SBA‐15 silica has been widely investigated due to its stable structure, modifiable surface properties, large specific surface area, and adjustable pore size [31,42–45] .…”

[9][10][31][32][33][34][35][36][37][38][39][40][41] Among them, functional mesoporous SBA-15 silica has been widely investigated due to its stable structure, modifiable surface properties, large specific surface area, and adjustable pore size. [31,[42][43][44][45] SBA-15 was used to adsorb dyes in wastewater (Haribandhu Chaudhuri et al, 2015), and the maximum adsorption of CR was 87.26 mg/g.…”

[19][20][21][22][23] For example, Yan et al synthesized a kind of 2D transition metal carbides, which exhibited excellent adsorption capability for cationic and anionic dyes.…”
