K2O_POP is a gel-like, strongly basic anion exchange resin. The tributylamine functional group enables targeted interaction with various anionic substance groups, including PFAS, as they arise and are treated in industrial processes or research environments.
The gel-like polymer matrix offers a stable structure, reliable functionality, and consistent performance under varying technical conditions.
The material is therefore designed for technical and analytical applications in industry and research.
PFAS are persistent pollutants found in firefighting foams, coatings, textiles, and industrial processes. Due to their chemical stability, they accumulate in groundwater and are resistant to conventional treatment processes. Health authorities worldwide are therefore introducing strict limits. Conventional methods such as activated carbon filtration often reach their limits with short-chain PFAS, while membrane technologies such as reverse osmosis entail costly concentrate management. K2O_POP is used in technical applications where classic adsorption or exchange materials are not optimally applicable.
K2O_POP is certified by the Water Quality Association (WQA) under the Gold Seal Program, confirming compliance with:
• NSF/ANSI 44 for water softening systems.
• NSF/ANSI/CAN 61 for drinking.
• Water system components.
• NSF/ANSI/CAN 372 for low lead content.
These certifications support its safe use in
residential and municipal water treatment
across global markets.
K2O_POP is characterized by high mechanical stability and uniform grain size distribution (≥ 93% whole grain), which favors its use under increased flow and pressure conditions. The bulk density (650–750 g/L) and moisture content (40–50%) enable reliable performance at flow rates of up to 20 bed volumes per hour, as can occur in industrial process conditions.
At higher dosages, clear adsorption profiles for both long- and short-chain PFAS emerge, consistent with what is typically observed in high-performance, gel-type strong-base anion exchange resins. These results highlight the technical potential of K2O_POP in industrial and research-driven applications. More detailed data can be provided upon request.
In dynamic column tests, K2O_POP demonstrated stable adsorption profiles for PFOS and PFOA under high-flow conditions. When evaluated alongside other anion exchange materials, the experiments showed distinct breakthrough behaviors, highlighting the robust functionality and consistent performance of K2O_POP in technical process environments.
K2O_POP has undergone various regeneration and reuse tests carried out by the manufacturer to simulate typical long-term operating conditions in technical applications. After several complete regeneration cycles, the material continued to demonstrate stable functional performance. This supports economical operation and highlights the resin’s potential for resource-efficient use, reduced waste generation, and extended service life.
In internal pilot tests, K2O_POP was evaluated under the same conditions as other commonly used exchange materials. The experiments showed different breakthrough and operating patterns for PFOS, PFBS, and PFBA, with K2O_POP maintaining stable behavior even at higher bed volumes. This suggests that the material performs reliably under more demanding process conditions.
K2O_POP can be integrated into a wide range of industrial and research-oriented process setups where gel-type anion exchange resins are used in fixed-bed or column systems. Its compatibility with common technical configurations makes it suitable for process optimization tasks and larger-scale operations.
The resin is supplied in the Cl⁻ form and offered in several practical packaging formats, including 1-cubic-foot valve bags, 50-liter and 200-liter drums, and 1-cubic-meter big bags, providing flexible handling and simple integration into existing process workflows.

K2O_POP is available in various formats suited for small- and large-scale applications:
Each package is sealed to maintain resin integrity and prevent contamination. Custom packing solutions are available upon request.
The resin should be stored above 0°C in dry, sealed containers away from direct sunlight. It must not be mixed with strong oxidizers due to exothermic reaction risk. Wetting dry resin leads to expansion and potential heat release. Follow standard safety procedures during handling and ensure compliance with local disposal regulations.
