Ion-Exchange Process Apparatus TRIZ Cases

A post-polymerization method converts sulfonfluoride groups into pendant ion exchange structures on fluorinated polymer backbones.

A carbon foam devolatilization process using atmospheric pressure heating of coal-derived pitch.

Two-stage ion exchange eliminates corrosive acids and reduces purification steps for high-purity silicic acid.

Inflatable seals block resin pathways during operation and open them for maintenance, eliminating dead areas and simplifying port structures.

Plate-like filler particles in a zeolite honeycomb article create anisotropic drying shrinkage that suppresses crack formation and improves mechanical strength.

A metal-organic framework-polymer fiber adsorbent with a core-shell structure achieves high rare earth metal adsorption capacity.

A nickel-cobalt alloy wetted surface resists peptide adsorption in chromatographic devices.

Adsorbent-based plasma exchange removes circulating drugs and exosomes to reduce systemic toxicity and drug resistance.

A vertically extending tube member directs coolant flow within an ion exchanger case to facilitate efficient resin replacement.

Nested retaining frit minimizes void volume to reduce peak dispersion and improve chromatographic efficiency.

Neutral alumina adsorbs sulfur from dihydroxynaphthalene to yield purified resin.

An amino phosphonic functionalized resin recovers uranium from acid leach solutions containing up to 80 g/L chloride without fouling or loading capacity loss.

Pentadentate ligand adsorbent reduces host cell protein binding and metal ion leakage in aggressive animal cell culture media.

Immobilizing selenium groups on silica creates specific binding sites that resolve low selectivity in toxic metal separation.

Rotational friction welding fuses the plug to the housing, preventing channeling and ensuring accurate separation.

A chromatographic apparatus uses a selection valve to route samples from multiple pharmaceutical process lines for rapid analysis.
