Use of weak cation exchange resin Lewatit S 8528 as alternative to strong ion exchange resins for calcium salt removal

Modelling mechanism of Ca2+ removal from dicyandiamide using dynamic ion exchange method

“…The methods applied to remove Ca 2+ impurities in solution, such as membrane separation, extraction, adsorption, chemical precipitation, and ion exchange, have been reported as successful, among which the ion exchange method has been reported as performing well. [13][14][15][16][17][18][19][20][21][22][23][24] Ion exchange has high equilibrium exchange capacity, strong selectivity, and simplicity of operation. [24] According to the research conducted by Yi et al, [21] the removal efficiency of Ca 2+ from a LiHCO 3 solution can reach 99.5% and achieve almost complete removal.…”

Purification of brines by chemical precipitation and ion-exchange processes for obtaining battery-grade lithium compounds

“…In addition to the elimination of impurities, all techniques aim to decrease the loss of lithium. Other studies evaluate the removal of divalent ions such as Ca +2 and Mg +2 using ion‐exchange resins …”

Profiling multiple static and transient puff-pastry characteristics with a robust-and-intelligent processor

“…Multiple quality properties of an infant formula have been tested with the Taguchi method to adjust several pneumatic conveying parameters (Hanley et al, 2011). Extraction processes are suitable for optimization as exemplified by the cases of isolating triterpenoid saponins from Ganoderma atrum , the calcium removal in tuning a weak-cation exchange resin (Coca et al, 2010), the microwave extraction of Chenopodium quinoa wild (Gianna et al, 2012), the enzyme-assisted maceration of waste carrot-seed oil (Ś migielski et al, 2014) and in supercritical fluid extraction (Sharif et al, 2014).…”
