The cations will displace H+ ions from the hydrogen ion form of the resin, and the hydrogen ion concentration resulting will be determined using a pH meter. The plastic cartridges hold 300mg of the ion exchange resin. The ion exchange capacity is about meq. Here meq means milliequivalents.
Ion Exchange Softening. Ionexchange is used extensively in small water systems and individual homes. Ionexchange resin, (zeolite) exchanges one ion from the water being treated for another ion that is in the resin (sodium is one component of softening salt, with chlorine being the other). Zeolite resin exchanges sodium for calcium and magnesium.
Ion exchange. Biomolecules that can be ionized: amino acids, peptides, proteins, etc. Along with absorption and adsorption, ion exchange is a form of sorption . Ion exchange is a reversible process, and the ion exchanger can be regenerated or loaded with desirable ions .

This study used ion exchange (IX) in dilute (domestic) wastewater to concentrate nutrients with subsequent recovery by struvite precipitation. This is the first tertiary wastewater treatment study directly comparing P removal using a range of Fe, Cu, and Albased media followed by clinoptilolite IX columns for N removal and precipitation using the combined regenerants.
Process Plants / Applications Our advanced membrane based process using micro/nano/ultra filtration, reverse osmosis and special ion exchange resins are used in filtration, separation and purification systems that play an essential role in food beverage processing.
tration. In both cases, the permeate may be discharged, reused in the process or polished with reverse osmosis for water recycling capabilities. Commodity Recycle and Recovery through Membrane Filtration and Ion Exchange Nanofiltration Applications: ECONO Features and Benefits: E Efficient design, simple durable.
Ion exchange resin has been used for many years in the recovery of uranium from both primary uranium producers, and from gold and copper mines as a byproduct. The current gold reefs mined at Gold Fields' Driefontein mine contain low levels of uranium. Small amounts of this uranium dissolve during normal operation of the mines.
Ion exchange was investigated for recovery of nitrogen as ammonium from urine for use as a fertilizer or disinfectant. Cation adsorption curves for four adsorbents (clinoptilolite, biochar, Dowex 50, and Dowex Mac 3) were compared in pure salt solutions, synthetic urine, and real stored urine.
1 ABSTRACT. Over the last few years Clean TeQ has been developing ion exchange technologies and process solutions for uranium recovery from leached pulps and solutions. Conventional hydrometallurgical extraction systems generally rely heavily on physical separation processes.
Ion exchange is used in nearly every part of the nuclear fuel cycle — from the purification of uranium from its ore to the final recovery of uranium and transmutation products. Ion exchange also plays a valuable role in the management of nuclear wastes generated in the fuel cycle. Keywords.
Recovery of Waste Ammonia in Ion Exchange Operation ROBERT H. COTTON, ... with the objective of reducing ammonia requirements in ion exchange by recovery of ammonia through distillation of spent anion regenerant. ... regeneration and the new system modified for recovery of ammonia. The process is covered by a patent application.
Ion exchange process for the recovery of uranium from a pregnant carbonate lixiviant employed in uranium leaching operations in which the lixiviant is passed over a precipitation inducing anionic ion exchange resin under conditions to load the resin predominantly with nonexchangeable uranium.
