Reverse osmosis (RO) and electrodialysis (ED) are the two most important membrane technologies for water desalination treatment. Their transport mechanisms very different, but on a closer look also have many similarities. In this tutorial review, we describe state-of-the-art theory both processes, focusing simple examples that helpful non-specialist classroom teaching. We relevant ion coupling ...

background: the effects of aqueous extract of fadogia agrestis stem at the doses of 18, 36, and 72 mg/kg body weight on alloxan-induced toxicity was investigated in wistar rats. methods: in total, 35 rats of both sexes (132.80±7.22g) were randomized into five groups (a-e): animals in group a received 0.5 ml of distilled water orally on daily basis for 15 days while the alloxanized rats in group...

We describe experimental and theoretical results that demonstrate the feasibility of power generation using concentration cells based on ionic concentration gradients and reverse electrodialysis. A peak power density of 0.2 (0.7) lW cm 2 and a maximum energy density of 0.4 (0.4) mJ cm 3 delivered in 3 h to a 2 (5) kX resistor were recorded using a microfiltration (anion exchange) membrane, resp...

14 The removal of the trace inorganic contaminants boron (B(OH)4 ), fluoride (F ) and nitrate (NO3 ) 15 from synthetic aqueous solutions containing organic matter using electrodialysis was investigated. 16 The transport of the contaminants through the ion-exchange membranes was evaluated in relation 17 to hydrated ionic radius, whereby a positive correlation was found in absence of organic matt...
