A Zn(II)-based metal–organic framework (MOF) compound and MnO2 were used to prepare ZnOx-MOF@MnO2 composites for selective Sr2+ removal in aqueous solutions. The characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, Brunauer–Emmett–Teller surface area analysis. functional groups, morphologies, thermal stabilities, specific areas of the suitable adsorption. maximum adsorption capacity 147.094 mg g–1 was observed batch experiments,...
A porous MgAl2O4 spinel-supported Mn3O4 catalyst, which is an efficient and robust catalyst for polyethylene terephthalate (PET) glycolysis, was synthesized from MgAl-layered double hydroxide (LDH) as a template via thermal chemical treatment, followed by Mn oxide loading. mesoporous structure in the spinel provided high surface area (278 m2/g) defects highly dispersed strongly stabilized substitution of Al3+ incorporation cation into defects. The strong interaction support led to dramatic...
A magnetically separable Co(II)-imprinted polymer based on mesoporous silica (mag@silica-CIP) was synthesized for use as an adsorbent the selective removal of Co(II). The optimal pH Co(II) adsorption found to be 5. Increasing amount layer surface mag@silica led increase in maximum capacity mag@silica-CIP selectively adsorbed even presence competing species such Fe(II), Ni(II), and Mn(II) ions. Thermodynamic experiments revealed that by is endothermic spontaneous process.
Three-dimensional (3D) double-network graphene oxide/alginate-polyacrylonitrile (GO/Ca-Alg2-PAN) composite hydrogels were synthesized via surface functionalization of GO to activate adsorption sites. The morphology and structure the GO/Ca-Alg2-PAN analyzed by scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA-DSC). results physicochemical analyses indicated that was successfully combination a...
Ciprofloxacin (CPX), a widely used antibiotic, was removed by synthesizing graphene oxide/calcium alginate-polyacrylamide (GO/Ca-Alg2-PAM) beads, three-dimensional double-network complex. The synthesis of GO/Ca-Alg2-PAM beads performed crosslinking and cation exchange mechanisms with oxide (GO), sodium alginate (Na-Alg), polyacrylamide (PAM). properties were confirmed using field emission scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis....
