Abstract It is known that the world scenario one of constant search for sustainable technologies can reduce emission carbon dioxide (CO 2 ) in atmosphere. This because CO seen as main responsible increase generation greenhouse gases, which leads to global warming and climate change. The development efficient adsorbents capture a current challenge. MCM-41 SBA-15 were synthesized microwave reactor used this work. Microwave irradiation presents itself an easy synthesis strategy with less...
The global demand for energy and industrial growth has generated an exponential use of fossil fuels in recent years. It is well known that carbon dioxide (CO2) mainly produced, but not only from fuels, which a negative impact on the environment, such as increasing emission greenhouse gases. Thus, thinking about reducing this problem, study analyzes microwave irradiation alternative to conventional heating optimize zeolite A synthesis conditions CO2 capture. Synthesis reaction parameters...
This research pioneers the application of microwave irradiation as an innovative strategy for one-pot synthesis and surfactant elimination (cetyltrimethylammonium bromide—CTAB) from MCM-41, introducing a rapid efficient methodology. MCM-41 silica is widely utilized in various applications due to its unique textural structural properties. Nonetheless, presence residual surfactants after poses challenge effective application. synthesis, conducted reactor at 60 °C, provided result within 0.5 1...
Industry and academia have shown great interest in the synthesis of organic–inorganic hybrid material because modification inorganic supports with organic groups increases options for using these materials. Microwave irradiation as a heat source is an alternative tool compared conventional heating (oil bath or furnace) to reduce reaction times during Thus, purpose this work was synthesize material, more specifically silica nanoparticles modified 3-chloropropyl-trimethoxysilane, microwave...
The possibility of producing new compounds that combine organic and inorganic materials for improved properties has become increasingly attractive to material science research. synthesis organic-inorganic hybrid materials, such as silica modified with an ionic liquid, is emerging alternative, because the porous matrix already used in several chemical fields, liquids have advantageous characteristics compared other compounds. However, involves long reaction times high temperatures. To...
Phenolic compounds are toxic pollutants that harmful to the human body and aquatic environments, with carcinogenic potential frequently found in industrial effluents at high levels. Adsorption processes often employed for removal of these compounds. Mesoporous materials based on modified silica amine have been used as adsorbents can be considered promising this job due its selectivity better adsorption capacity when compared without any modifications. In addition, studies performed using...
Diante dos problemas causados pelos compostos sulfurados nas refinarias, nos motores de automóveis e ao meio ambiente, os órgãos controle ambiental (Conama) estabeleceram novos regulamentos para reduzir o teor enxofre combustíveis. Este trabalho desenvolveu um novo material adsorvente, agregando orgânicos ionizados (líquido iônico, LI) em adsorvente sólido (sílica) remoção dibenzotiofeno presentes no petróleo. O foi seletivamente removido por adsorção utilizando N – metil imidazólio com N(Tf2)
A vasta utilização da anilina na indústria química e farmacêutica gera uma grande quantidade de águas residuais que precisam ser tratadas, pois a afeta negativamente tanto qualidade ambiental como saúde humana. presente nas deve conhecida para não ultrapassem os limites permitidos descarte em meios coletores. Sendo assim, técnicas analíticas separação posterior quantificação deste composto estão sendo estudas, bem síntese novos materiais apresentam interação seletiva pela anilina. híbridos...
Abstract MCM-41 silica is widely utilized in various applications due to its unique textural and structural properties. Nonetheless, the presence of residual surfactant after synthesis poses a challenge effective application. This study explores utilization microwave irradiation as promising approach for one-pot removal (cetyltrimethylammonium bromide - CTAB) MCM-41, offering fast efficient methodology.
