چکیده
Abstract Mesoporous silica is an inorganic material that has high potential to be applied in various industrial fields, one of its applications the adsorption method. To maximize mesoporous silica, modification surface was carried out by adding amine compounds. The compound used as a modifier dimethylamine (DMA), using glycidoxypropyltrimethoxysilane (GPTMS) linking compound. column method uses modified with dimethylamine, nitrate anions process. capacity anion 0.0917 mg/g. After adsorbed, desorption process release adsorbed anions. found HCl best agent on optimum concentration 0.15 M, number desorbed much 0.0459 mg 100% percentage.

15 صفحه اولMechanisms and Kinetics for Sorption of CO2 on Bicontinuous Mesoporous Silica Modified with n-Propylamine
We studied equilibrium adsorption and uptake kinetics and identified molecular species that formed during sorption of carbon dioxide on amine-modified silica. Bicontinuous silicas (AMS-6 and MCM-48) were postsynthetically modified with (3-aminopropyl)triethoxysilane or (3-aminopropyl)methyldiethoxysilane, and amine-modified AMS-6 adsorbed more CO(2) than did amine-modified MCM-48. By in situ FT...

N-Propylsalicylaldimino-functionalized SBA-15 mesoporous silica was prepared, characterized and used as an adsorbent for heavy metal ions. The organic-inorganic hybrid material was obtained using successive grafting procedures of SBA-15 silica with 3-aminopropyl-triethoxysilane and salicylaldehyde, respectively. For comparison an amorphous silica gel was functionalized using the same procedure....

A novel label-free immunoassay strategy for sensitive detection of α-fetoprotein (AFP) was proposed based on controlled fabrication of single-wall carbon nanotubes (CNTs) inside the channels of mesoporous silica (MPS). The silanol groups on the internal pore walls of MPS were grafted with amino groups, while the silanol groups on the external surface were blocked by trimethylchlorosilane (TMCS)...
