How IC is helping us provide more accurate, reliable, and insightful environmental solutions. Ion chromatography (IC) is an analytical chemistry technique to analyze ions and polar molecules via liquid chromatography. This is a separation technique that uses a liquid mobile phase to separate components of a mixture, based on their interaction with a stationary phase. IC is highly versatile, ...
YTEDBM-A: Two-compartment type for acid production This setup includes a bipolar membrane and a cation exchange membrane. It is designed to convert organic acid salts (e.g., sodium acetate) into their free acid forms (e.g., acetic acid), with sodium hydroxide as a by-product. ...

Understand the sources, risks, and evolving technologies in the fight against forever chemicals in water treatment PFAS, better known colloquially as “forever chemicals” or “persistent organic pollutants” (POPs), stands for per- and polyfluoroalkyl substance(s). These chemicals contain multiple carbon-fluorine bonds, which are extremely strong and stable, allowing them to ...
Boron is a nonmetallic element that occurs in industrial waters primarily in two forms: as nonionized boric acid and at pH greater than 11 as the borate ion. pH’s from 7.5 to 10.5 represent a mixture of both the acid and borate forms. RO, anion exchange and adsorbents are the current accepted removal technologies. ...
However, it is limited by length, column capacity, and limited purification.Desalination PurificationFor oligonucleotides without DMT protecting groups, the collected oligonucleotide solution after electrophoresis separation and anion exchange liquid chromatography purification needs further desalination. ...
Ion exchange can be divided into two types: anion exchange chromatography and cation exchange chromatography, collectively known as anion-cation chromatography. In terms of elution methods, anion exchange chromatography primarily involves changing the ion strength concentration ...
Ion exchange resin is used not only for producing pure boiler feedwater but also for the condensate polishing plant (CPP), which removes various impurities accumulated in boilers that use condensate water. ...
Commonly employed techniques include lectin microarrays, reversed-phase liquid chromatography (RPLC), hydrophilic interaction chromatography (HILIC), anion exchange chromatography (AEX), porous graphitic carbon (PGC), and Capillary electrophoresis (CE). ...
Quality control Various methods for quality control of polysaccharide vaccines, such as size exclusion chromatography (SEC), high-performance anion-exchange chromatography coupled with pulsed amperometric detection (HPAEC-PAD), and nuclear magnetic resonance ...
How Do Ion Exchange Resins Work? l Structure Ion exchange resins are composed of three parts: the insoluble three-dimensional space network polymer skeleton, the ion functional group connected to the skeleton, and the exchangeable ion pore with opposite charges on the functional group. ...
Knowing what a pH electrode does is quite simple—It measures the difference in hydrogen ions between two solutions. How an electrode performs this measurement is significantly more complicated, however, but it is worth understanding to ensure proper use in an application. This article provides thorough but easy-to-follow examples showing how a pH electrode works, with the only background ...
What is it that makes your clothing repel water or your cookware have nonstick properties? The answer could be the use of per- and polyfluorinated alkyl substances (PFASs) to coat these materials. This blog article explains how PFASs and other halogenated organic compounds have been used over the past several decades, their effects on our health and the environment, and how to monitor and ...
Various polyacrylate particles products are ready for your research use, such as DiagNano™ DEAE Porous Polyacrylate Particles, 80 μm, which are monodisperse, porous polyacrylate (PA) microparticles used for ion exchange chromatography with high loading capacity. These microparticles with DEAE (weak anion exchange, WAX) groups on the ...
These ions easily pass through the negatively charged cation exchange membranes, but are retained by the positively charged anion exchange membranes. Similarly, negatively charged anions migrate towards the anode, pass through the anion exchange membrane and are retained by the cation ...

Introduction: India is the largest consumer of groundwater in the whole world. It uses around 230 cubic kilometers of groundwater per year, which is over a quarter of the global total. More than 60 percentage of groundwater in India is used for irrigation, whereas almost 85% of groundwater is used for drinking purposes. Even though groundwater is a renewable water resource, the world’s ...

Researchers at Ewon University in Japan have recently developed a new method to significantly shorten the preparation time by anion exchange solid phase extraction centrifugal columns. The findings were recently published in Chemical Communications. ...
Although many water purification technologies are available, ion exchange is well-suited for highly selective removal of specific contaminants Ion exchange is a water treatment process commonly used for water softening or demineralization, but it also is used to remove other substances from the water in processes such as dealkalization, deionization, denitrification, and disinfection. With many ...
