Electrically regenerated ion-exchange technology: Leveraging faradaic reactions and assessing the effect of co-ion sorption

Sorption Ion Exchange

The case of a sorption process considered here involves a solid phase (sorbent) and a liquid phase (solvent, normally water) containing a dissolved species to be sorbed (sorbate, e.g. metal ions). Due to the higher ‘affinity’ of the sorbent for the sorbate species the latter is attracted into the solid and bound there by different mechanisms. This process takes place until an equilibrium is est...

Ion Exchange Reactions of Clays

I t has been recognized for many ypars that many aspects of clay technolofcy including soil treatment and drilling nnul treatment must remain in an essentially empirical state until a basis for the understanding of ion exchange reactions is established. Much of the work on ion exchange reactions of clays in the i)ast has been directed toward establishing total exchange capacities or determining...

Effect of Extremely High Specific Flow Rates on the Ion- Exchange Resin Sorption Characteristics

Behavior of the strongly basic, macroporous ion-exchange resin Amberlite IRA 958Cl is circumstantially explained in the book chapter. Effects of different specific flow rate (SFR) and determination of its optimum value, as well as effects of the empty-bed contact time (EBCT) values on the removal of NOM, arsenic, sulfate, electrical conductivity, bicarbonate and chlorine from groundwater using ...

fabrication of new ion sensitive field effect transistors (isfet) based on modification of junction-fet for analysis of hydronium, potassium and hydrazinium ions

a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
