in this study, a novel solid dendrimer amine (hyperbranched polymers) was prepared using mesoporous carbon nitride functionalized by melamine based dendrimer amines. this adsorbent was denoted mda-mcn-1. the process was stepwise synthesis and hard-templating method using mesoporous silica sba-15 as a template. cyanuric chloride and n,n-diisopropylethylamine (dipea, merck) were used for function...

Millimetre-sized mesoporous carbon spheres (MMCSs) with smooth surface and penetrating mesoporous channels have been successfully prepared by an emulsion-EISA technique, and are found to be a much better bilirubin adsorbent than commercial activated carbon spheres. Hemolysis and coagulation assays of MMCSs indicate that they have negligible hemolysis effect and do not induce blood coagulation.

This study explored the possibility of recovering waste powder from photonic industry into two useful resources, sodium fluoride (NaF) and the silica precursor solution. An alkali fusion process was utilized to effectively separate silicate supernatant and the sediment. The obtained sediment contains purified NaF (>90%), which provides further reuse possibility since NaF is widely applied in ch...

The adsorption of phosphate onto mesoporous TiO2 was investigated in order to reduce phosphorus concentrations in wastewater and provide a potential mode of phosphorus recovery. Three equilibrium isotherms were used to optimize and properly describe phosphate adsorption (R > 0.95). The maximum capacity of phosphate on the adsorbent was found to be 50.4 mg/g, which indicated that mesoporous TiO2...

An efficient and economic approach is proposed for the fast and direct recovery of silica materials from photonic waste powder. Unlike the conventional alkaline fusion method for the extraction of silica from waste materials, this method possesses advantages of a rapid and low-energy-consumed process with total recovery yield. The obtained mesoporous silica material, denoted as MCM-41(DU)-F, wa...

Adsorption of methanol and ethanol over mesoporous siliceous material are studied in the current paper. The pure mesoporous silica is prepared using tetraethylorthosilicate (TEOS) as silica source and dodecylamine as template at low pH. The prepared material was characterized using nitrogen adsorption,nX-ray diffraction (XRD) and scanning electron microscopy (SEM). The adsorption kinetics of me...

in this study, mesoporous mcm-41 has been modified by incorporation of aluminum ion asa rapid, simple and inexpensive method for modification. the adsorbent is characterized usingpowder x-ray diffraction and nitrogen adsorption-desorption isotherm data. the distributioncoefficient of cadmium ion on the mesoporous aluminosilicates has been enhanced with theincrease of the aluminum in the framewo...

To counter environmental threats to the water resources polluted by NH, which is common in wastewaters and agricultural runoff, adsorption using mesoporous functional materials represents a promising alternative to existing treatment methods. In this study, adsorption of NH ions from aqueous solutions was investigated on arene- and propylsulfonic acid functionalized SBA-15 mesoporous silica mat...

We successfully developed a single-step detection and removal unit for Bi(III) ions based on dithizone (DZ) anchored on mesoporous TiO2 with rapid colorometric response and high selectivity for the first time. [(DZ)3-Bi] complex is easily separated and collected by mesoporous TiO2 as adsorbent and preconcentrator without any color change of the produced complex onto the surface of mesoporous Ti...
