and a draw solution separator receives a heated draw solution which then decomposes into ammonia, CO2and water. Potable water is separated from ammonia and CO2gas. Subsequently, the ammonia gas and CO2gas are recombined with a portion of the potable water stream to reform the ammonium bicarbonate...
(Boubakri et al., 2015), removal of fluoride from aqueous solutions (Boubakri et al., 2014), removal of ammonia from dilute solutions of water using MD (Ding et al., 2006;Duong et al., 2013),and removal of uranium and concentrations ofdeuteriumand Oxygen 18 Isotope in water using ...
Further, the aqueous medium may also be a buffer solution such as a Good's buffer solution, a Tris buffer solution, a phosphate buffer solution, a glycine buffer solution, and an ammonia buffer solution. In this regard, the aqueous medium may contain a lower alcohol such as methanol, ethano...
as ammonia solution 25% (suprapur) were obtained from Merck (Darmstadt, Germany). Ethanol 95% was from Kemetyl (Haninge, Sweden). Methanol was ob- tained from Labscan (Dublin, Ireland) and glyceral- dehyde was from Riedel-de Ha€een GmbH (Seelze, Germany). Preparation of mixture of LAT...
In one embodiment, the deoiled and dried spent catalyst particles first leached with an aqueous solution containing ammonia and air in an autoclave, i.e., a multi-chambered, agitated vessel at a sufficient temperature and pressure, in which ammonia and air are supplied to induce leaching ...
An ammonia solution was used as internal phase. Gas emissions were measured from outside the liquid marbles using two colorimetric detection techniques. The first method implied UV-Vis spectrometric measurements of absorbance depending on concentration of CuCl2 indicator solution, after exposure to ...
The addition of CaO, MgO or Ca(OH)2 would care an increase in pH and promote precipitation of phosphate as calcium phosphates or calcium carbonates [5], while ammonia could be removed by stripping of the subsequent UF permeate. Pramanik et al. [116] used a flat sheet FO membrane to ...
