Macroporous Adsorbent Resins - MDPI
was evaluated by adsorption using commercially available, macroporous polymer-based adsorbents, HP20 and HP2MGL, which are styrene (St)- and methyl methacrylate (MMA)-based crosslinked resin beads, respectively. The effect of the macroporosity and chemical structure of the macroporous adsorbent resins (MARs) on the adsorption behavior was
We offers 517 macroporous resins products. About 67% of these are polymer, 11% are water treatment, and 2% are other pharmaceutical machinery. A wide variety of macroporous resins options are available to you, such as synthetic resin and plastics, synthetic fibers, and synthetic rubbers.
Adsorption process optimization for phenolic wastewater
The treatment of phenolic wastewater was studied with macroporous resins. Under the experimental conditions (C 0 = 877 mg·L –1 , t = 2.5 h and pH 7), the favorable resin was selected upon the
Adsorption on resin is a simple technology that has found widespread application in the treatment of industrial effluents [1, 2]. In order to improve the adsorption efficiency and economize the use of macroporous resins, many studies on surface modifications have been carried out, and they mainly focus on chemical modifications [3–6].
Understanding Ion Exchange Resins for Water Treatment Systems
Macroporous resins are usually manufactured with high levels of crosslinking. There are, however. macroporous resins produced with crosslinking lev-els similar to those of gel resins. In either case, the macroporous resins have slightly less capacity than corresponding gel resins. Some resin manufacturers believe that this difference is
Gel resins generally can be characterized as having smaller pores (approx. 1 to 2 nm, hydrated) in the resin structure, higher initial exchange capacity and a lower price than macroporous resins of the same type. But macroporous resins are usually considered for their ability to elute foulants more effectively due to the larger pore structure

Separation and purification of rebaudioside A from extract
porous resins have a high adsorption capacity, certain selectivity, low cost, easy regeneration and have a good stability7–8. Macroporous Adsorption Resin (MAR) has been extensively used in the fi elds of chromatography analysis, water treatment industry and etc. However, little studies on their use for the extraction of natural
However, membrane fouling limits the application of MBR. This study investigated membrane fouling in a macroporous adsorption resin–membrane bioreactor hybrid system established by adding macroporous adsorption resin (MAR) into MBR. MAR addition increased the critical flux by 27.97%, indicating that membrane fouling was successfully mitigated.
- What is polyacrylamide (PAM) used for?
- npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- What is high molecular weight polyacrylamide (PAM)?
- Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- What is Pam used for in water treatment?
- PAM is also widely used as a flocculant in drinking water treatment (at concentrations <1 mg/L). 37 PAM can create bridges between destabilized particles, forming micron-size aggregates with good settling properties. 38 Cationic, nonionic, and anionic PAM have all been studied for flocculation.
- Can polyacrylamide improve hydrocarbon production efficiency?
- npj Materials Sustainability 2, Article number: 15 (2025) Cite this article Polyacrylamide (PAM) and its derivatives play a pivotal role in various facets of hydrocarbon development. Proper application and treatment of PAM have the potential to enhance hydrocarbon production efficiency while mitigating adverse environmental effects.
