The presence of various types of contaminants such as heavy metals, emerging organic contaminants, pesticides, organic waste, organic dyes, radionuclide’s, fluorides, etc. cause water pollution. These pollutants are of concern to engineers, environmentalists and scientists. Due to the lack of freshwater, it is very important to recycle the wastewater after treatment to remove organic contaminates and heavy metal pollutants.

There are more than 100 million patients with various stages of chronic kidney disease (CKD) with decrease in CKD1 to loss in CKD 5 (end stage renal disease, ESRD) in the ability of the kidney to excrete K+ causing hyperkalemia and potentially heart attack. To avoid hyperkalemia, kidney patients have to drastically limit the consumption of fruit and vegetable juices that significantly decreases the nutritional value of their diet.

The adsorption of Cu(II) ions from aqueous solution onto alginic acid has been investigated based on the establishment of a relationship among pH, conductivity and the concentration of metal ion. It was shown that the adsorption of this metal ion onto alginic acid followed the pseudo-second-order reaction and was conducted by ion exchange mechanism.

The ketalization reaction of glycerol with acetone for solketal formation was performed using a gel-type ion exchange resin, Indion 225H in a solvent-free medium. The experimental parameters molar ratio, catalyst loading, rate of stirring, and temperature were analyzed and evaluated for their impact on the conversion of glycerol. A kinetic model based on the Langmuir–Hinshelwood–Hougen– Watson (LHHW) equation described the kinetics of the heterogeneous system.

Currently, Cr(III) and Cr(VI) are analyzed directly in trace level using anion-exchange liquid chromatography inductively coupled plasma mass spectrometry (LC – ICP – MS), which is wellknown as an expensive and complicated method. Therefore, determination of Cr(VI) and Cr(III) by spectrometer or combine with ICP (or AAS) is seemly prefer to choose in almost laboratories although this method presents a higher limit of detection (LOD) and is influenced by salt ions in seawater.

The enzymatic synthesis of fructooligosaccharides (FOS) was carried out using a partially purified -fructofuranosidase from the commercial enzyme preparation Viscozyme L. Partial purification of -fructofuranosidase from Viscozyme L was done by batch adsorption using ion-exchange resin DEAESepharose, showing a 6-fold increase in specific activity.

In the past decades, research was carried out to find cost-efficient alternatives to Protein A chromatography as a capture step in monoclonal antibody (mAb) purification processes. In this work, polyethylene glycol (PEG) precipitation has shown promising results in the case of mAb yield and purity. Especially with respect to continuous processing, PEG precipitation has many advantages, like low cost of goods, simple setup, easy scalability, and the option to handle perfusion reactors

The ion-exchange and complex forming equilibria were quantitatively described and demonstrated in order to understand major factors in the control of selectivity in the analytical separation of carboxylic acids and inorganic anions in cryptand based ion chromatography. A complex retention model has been developed for the separation on a non-conventional IC column.

In this study, we present results obtained on the enantioseparation of some cationic compounds of pharmaceutical relevance, namely tetrahydro-ß-carboline and 1,2,3,4-tetrahydroisoquinoline analogs. In highperformance liquid chromatography, chiral stationary phases (CSPs) based on strong cation exchanger were employed using mixtures of methanol and acetonitrile or tetrahydrofuran as mobile phase systems with organic salt additives.
