Ice-templated porous polymer/UiO-66 monolith for Congo Red adsorptive removal

Effective removal of Basic Red 12 dye by novel antimicrobial trimellitic anhydride isothiocyanate-cross-linked chitosan hydrogels

“…Chitosan is also abundant, hydrophilic, biologically compatible, biologically degradable, renewable and nontoxic. 6…”

“…Chitosan is also abundant, hydrophilic, biologically compatible, biologically degradable, renewable and nontoxic. 6 Chitosan easily dissolves in acidic media, and this is considered as its worst drawback, particularly in case of its employment as adsorbent for dyes removal because the effluent is commonly acidic. Consequently, controlling the solubility of chitosan is considered a desirable property for such applications.…”

Adsorption behavior of Congo red on a carbon material based on humic acid

“…Congo red is a typical anionic azo dye. Its physical and chemical properties is listed in Table 1 below [18], [19], [20], [21] . Due to its complex aromatic structure, high chemical stability and thermal stability.…”

Synthesis of macroscopic monolithic metal–organic gels for ultra-fast destruction of chemical warfare agents

“…The application of Zr-MOF powders is greatly hampered, due to their inherent problems such as particle aggregation, poor processability and handling, mass transfer limitations, and signicant pressure drop in an adsorption bed. [11][12][13][14][15] To overcome the issues of Zr-MOF powders, many methods have been reported to construct Zr-MOF macroscale structures by either integrating Zr-MOFs into support materials such as bers, [16][17][18] polymeric monoliths 19,20 and foams, [21][22][23] or pelletizing Zr-MOF powders via mechanical compression or extrusion. [24][25][26] However, both strategies still have issues such as reduced adsorption capacities, due to the use of Zr-MOF as a secondary component, and pressure-induced losses of crystallinity and porosity.…”
