Purification technologies for crude biodiesel obtained by alkali-catalyzed transesterification
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
For commercial application, the ester product of alkali-catalyzed transesterification of vegetable oil or animal fats should be refined after glycerol separation by settling to fulfill the biodiesel standard specifications. ...
Ultrasonic assisted arsenate adsorption on solvothermally synthesized calcite modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier, Amsterdam, 2014)
A highly porous calcium carbonate (calcite; sorbent 1) was used as a support for modification with alpha-FeOOH (calcite/goethite; sorbent 2), alpha-MnO2 (calcite/alpha-MnO2; sorbent 3) and alpha-FeOOH/alpha-MnO2 ...
Metal | polypyrrole battery with the air regenerated positive electrode
(Elsevier Science Bv, Amsterdam, 2014)
Recharge characteristics of the battery based on the electrochemically synthesized polypyrrole cathode and aluminum, zinc, or magnesium anode in 2 M NH4Cl are investigated. It is shown that polypyrrole electrode can be ...
