A B S T R A C TThe adsorpion of methylene blue (MB) from aqueous solution on a highly porous metal-organic framework material [Cu 3 (BTC) 2 (H 2 O) 3 ] was studied in conjunction with the adsorption isotherm, kinetics and regenerate of the sorbent. The adsorption isotherms of MB on [Cu 3 (BTC) 2 (H 2 O) 3 ] followed both the Freundlich isotherm and the Langmuir adsorption isotherm. Adsorption kinetics was determined from the experimental data, and the results showed that the adsorption obeyed a pseudo-second-order kinetics. The best oscillate time and the best [Cu 3 (BTC) 2 (H 2 O) 3 ] amount were discussed, and [Cu 3 (BTC) 2 (H 2 O) 3 ] gave high adsorption in only 5 min. The used [Cu 3 (BTC) 2 (H 2 O) 3 ] could be regenerated by glycol solution, thus recycled. SEM image and FT-TR spectra of recycled [Cu 3 (BTC) 2 (H 2 O) 3 ] after different adsorption times were compared. The high adsorption capacity and excellent reusability make [Cu 3 (BTC) 2 (H 2 O) 3 ] attractive for the removal of MB from aqueous solution.
Anosovite (Mg0.3Ti2.7O5) phase was successfully separated from synthesized titanium bearing blast furnace slag by super gravity. Supposing that the titanium exists in the slag in terms of TiO2, the mass fraction of TiO2 is 23.49% in the parallel sample without centrifugal separation. With the parameter of t=5min, T=1553K and the gravity coefficient ranged from 600 to 1000, the mass fraction of TiO2 in the concentrate increase from 40.17% to 58.35%, while the recovery ratio of Ti in the concentrate slightly decrease from 83.49% to 81.81%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
