The removal of contaminants from liquid effluents by the adsorptive particulate flotation (APF) process, including new adsorbents and flotation devices, are reported. Herein, contaminants are adsorbed (and/or absorbed) ...

Second generation ethanol has the prospect of becoming an important bioenergy alternative. The development of this technology is associated with the lignocellulosic materials' use, with emphasis on agricultural and ...

The use of groundwater to obtain water for human consumption is an alternative for places where there is no nearby surface spring available, or where there is no water treated by concessionaires being distributed to ...

Advanced treatment methods using alternative adsorbent materials may replace or complement existing conventional treatments, aiding the removal of toxic substances coming from industrial processes. Spectrometry and biological ...

© 2021, Springer Nature Switzerland AG.Purpose: This research aimed to develop activated carbons from tobacco by double (thermal-physical) and triple activations (thermal-chemical-physical) for high-efficiency removal of ...

In this study, use was made of tucumã cake, in natura (TCN) and thermally treated (TCT), as potential alternative adsorbents for the adsorption of cationic and anionic dyes. The effects of the parameters: contact time, ...

BACKGROUND: ‘Expanded’ composite materials are of interest as an alternative, or as a supplement, to packed-bed chromatography during bioproduct recovery and purification. Functionalized non-woven fabrics and mega-porous ...

In chemical ecology studies (insect-insect, insect-plant relationships), it is important to choose the appropriate sampling methods and the correct optimization of sampling by using dynamic systems. In the present work, ...
