High Na+ levels are detrimental for most crops. Selective membranes provide the possibility for the selective removal of Na+ while preserving beneficial ion species. The challenge is to separate two ion species of the same charge. This study evaluates the im ...
Electrodialysis (ED) is a membrane-based process in which ions are transported under the influence of an externally applied electrical potential. Ion-exchange membranes (IEMs) are key components in ED processes. There are two types of IEMs: (1) cation-exchange membranes (CEMs), w ...
We investigated in detail the permeation selectivity in the electro-dialysis of Na+, K+, Mg2+ and Ca2+ in both binary and quaternary mixtures using a supported liquid membrane (SLM). The SLM consisted of the organic liquid 2-nitrophenyl ...
This study demonstrates the effective separation of alkali metal cations using a Supported Liquid Membrane (SLM) containing lipophilic, negatively charged borate moieties, operating under electro dialysis conditions. The selectivity of the membrane is essentially based on differe ...
Selective ion removal has been a point of focus in capacitive deionization because of its industrial applications such as water purification, water softening, heavy metal separation and resource recovery. Conventionally, carbon is used as electrode material for selectivity. Howev ...
A model is presented for the Na+ and K+ levels in the irrigation water of greenhouses, specifically those for the cultivation of tomato. The model, essentially based on mass balances, not only describes the accumulation of Na+ but includes a membr ...
