Synthesis of new pyrazolium based tunable aryl alkyl ionic liquids and their use in removal of methylene blue from aqueous solution
In this study, two new pyrazolium based tunable aryl alkyl ionic liquids, 2-ethyl-1-(4-methylphenyl)-3,5- dimethylpyrazolium tetrafluoroborate (3a) and 1-(4-methylphenyl)-2-pentyl-3,5-dimethylpyrazolium tetrafluoroborate (3b), were synthesized via three-step reaction and characterized. The removal of methylene blue (MB) from aqueous solution has been investigated using the synthesized salts as an extractant and methylene chloride as a solvent. The obtained results show that MB was extracted from aqueous solution with high extraction efficiency up to 87 % at room temperature at the natural pH of MB solution. The influence of the alkyl chain length on the properties of the salts and their extraction efficiency of MB was investigated

SBE16 Brazil & Portugal - Sustainable Urban Communities towards a Nearly Zero Impact Built Environment
Vol. IThe organizers of SBE 16 Brazil & Portugal were challenged to promote discussions and
the development of solutions for an important and, at the same time, very ambitious topic
? Sustainable Urban Communities towards a Nearly Zero Impact Built Environment. This
is the main focus of the international conference SBE16 Brazil & Portugal; the only event
of the SBE16/17 conference series being held in Latin America, more precisely, in VitĂłria
(EspĂrito Santo), Brazil, from the 7th until the 9th of September 2016. The conference
offered a unique opportunity to bring together researchers from all over the world to
share evidence-based knowledge in the field and succeeded to achieve its goals since many
contributions from various parts of the planet were received, addressing a tiny part of the
problem or trying to perform the difficult task of making the sum of the parts a coherent
