Cation Exchanger Materials TRIZ Cases

A sorbent recharger system manages effluent pH through automatic neutralization of zirconium phosphate and oxide streams.

Calcium cations precipitate bacterial extracellular vesicles to resolve low yield and purity issues in large-scale commercial production.

Single cationic ion exchange replaces dual-step purification, lowering ash content and processing time for oligosaccharide solutions.

A lithium carbonate recovery method uses carbon dioxide water leaching to extract lithium from battery scrap powder.

Segmented distillation with pH control removes propylene oxide and glycidol, achieving high purity levels in biobased propylene glycol production.

Washing an acidic cation exchanger with organic solvent reduces water content to prevent decomposition of acid-sensitive polymers during metal ion extraction.

Discontinuous elution gradients resolve empty and full AAV capsid peaks to reduce immune response risks.

Aligning inlet and outlet passages at the same end reduces volume while maintaining reliable water flow.

Using monoethylene glycol to soak the resin prevents structural degradation while reducing aldehyde content below 15 ppm.

Continuous chromatography removes impurities while seed cooling induces large crystal growth without ethanol.

Multistep chromatography with nuclease wash buffers degrades residual nucleic acid impurities, enabling scalable production of pure extracellular vesicles.

Amino-modified cellulose nanofibers selectively remove endotoxins while resisting ionic interactions with acidic proteins.

Chromatography removes unreacted fructose while controlled cooling maintains supersaturation, producing 98% pure crystals with MA200 grain size.
