Keep in mind the importance of cadmium, cobalt and nickel ions as environmentally and economically strategic heavy metals, the application of two acidic extractants, named bis(2-diethylhexyl)phosphoric acid (DEHPA) and 2-thenoyltrifluoroacetone (HTTA), was assessed for the extraction-recovery of these ions from leached solution of spent rechargeable Ni-Cd batteries. The conditions for leach...

Abstract Ions that are reflected at the shock front and escape back into upstream region can play role of ions start to be accelerated by a diffusive acceleration mechanism. Backstreaming have been shown generated from superthermal tail solar wind sufficiently high temperatures. The number such was found low they were not angles exceeding 50°. mechanism production is multiple reflection when an...
