Poly(sodium 4-styrenesulfonate) Is Used for the Selective Depression of Calcite in Scheelite Flotation Systems

Poly(sodium 4-styrenesulfonate) Is Used for the Selective Depression of Calcite in Scheelite Flotation Systems Chen, Jiali, et al. Advanced Powder Technology 35.11 (2024): 104664.

Poly(sodium 4-styrenesulfonate) (PSS) has been successfully applied as a novel selective depressant in the flotation separation of scheelite and calcite using sodium oleate (NaOL) as the collector. Under optimized conditions (10 mg/L NaOL, 10 mg/L PSS, pH 8), PSS enabled high scheelite recovery (87.18%) while strongly depressing calcite recovery (5.57%) in single mineral flotation. In artificial mixed ore flotation, the WO₃ recovery and grade reached 70.53% and 61.08%, respectively.
Mechanistic investigations using contact angle measurements, zeta potential analysis, FT-IR, AFM, and XPS revealed that PSS does not interact chemically with the surface of scheelite, allowing NaOL to adsorb unimpeded and maintain flotation activity. In contrast, PSS chemisorbs onto the calcite surface through interactions between the Ca²⁺ sites of calcite and the sulfonate oxygen atoms of PSS. This increases the hydrophilicity of calcite and inhibits NaOL adsorption, thereby suppressing its flotation.
This selective chemisorption behavior allows PSS to act as an efficient and environmentally benign depressant for calcite, without compromising scheelite recovery. The study demonstrates the application potential of Poly(sodium 4-styrenesulfonate) in improving the separation efficiency of complex calcium-bearing mineral systems and provides valuable mechanistic insights for designing targeted flotation reagent strategies in mineral processing.

Poly(sodium 4-styrenesulfonate) Is Used for the Preparation of High-Permeance Polyamide Nanofiltration Membranes via Network-Like Interlayer Engineering

Poly(sodium 4-styrenesulfonate) Is Used for the Preparation of High-Permeance Polyamide Nanofiltration Membranes via Network-Like Interlayer Engineering Zheng, Pingyun, et al. Journal of Colloid and Interface Science 662 (2024): 707-718.

Poly(sodium 4-styrenesulfonate) (PSS) has been employed as a key component in the fabrication of high-performance thin-film composite (TFC) nanofiltration membranes, enhancing water permeance without compromising selectivity. In this study, PSS was integrated with tannic acid (TA) to construct a hydrophilic, network-like interlayer on a PVDF substrate. The TA/PSS interlayer, formed through hydrogen bonding and ionic interactions, served as a functional platform for subsequent interfacial polymerization between piperazine (PIP) and trimesoyl chloride (TMC).
The TA/PSS interlayer significantly improved membrane hydrophilicity and controlled monomer diffusion, particularly by retarding the release of PIP during polymerization. This modulation led to the formation of a thinner and more uniform polyamide active layer (≈38.9 nm), thereby enhancing water flux while maintaining high salt rejection. The optimized membrane (TFC-2) exhibited a pure water flux of 22.7 ± 2.8 L m⁻² h⁻¹ bar⁻¹ and Na₂SO₄ rejection of 97.1 ± 0.5%.
This approach underscores the versatility of PSS as an interlayer-forming polyelectrolyte, rich in sulfonic acid groups, enabling strong interactions with amine monomers. The strategy provides a scalable and efficient route to construct high-flux, selective nanofiltration membranes, advancing the design of next-generation separation materials through molecular-level interfacial engineering.

Poly(sodium 4-styrenesulfonate) Is Used for the Preparation of High-Performance Hybrid Humidity Sensors Based on ZnO-Co₃O₄ Nanofibers

Poly(sodium 4-styrenesulfonate) Is Used for the Preparation of High-Performance Hybrid Humidity Sensors Based on ZnO-Co₃O₄ Nanofibers Andre, Rafaela S., et al. Journal of Alloys and Compounds 767 (2018): 1022-1029.

Poly(sodium 4-styrenesulfonate) (PSS), a strong anionic polyelectrolyte, has been employed to significantly enhance the performance of nanostructured humidity sensors. In this study, one-dimensional ZnO-Co₃O₄ heterostructure nanofibers (NFZCo) were synthesized via electrospinning followed by high-temperature calcination. These nanofibers were subsequently surface-modified with PSS to form a novel hybrid material, NFZCo-PSS, which functions as a chemoresistive humidity sensor operating effectively at room temperature.
The integration of PSS introduced abundant sulfonic acid groups, significantly increasing the hydrophilicity of the sensing surface and improving adsorption/desorption kinetics of water molecules. The NFZCo-PSS sensor exhibited a strong, linear electrical resistance response across a wide relative humidity (RH) range of 25-75%, with a rapid response time of less than 5 s and stable recovery characteristics. Compared to unmodified NFZCo, the PSS-functionalized sensor showed superior sensitivity, repeatability, and stability.
The enhanced sensing performance is attributed to the synergistic effect between the high surface area of the ZnO-Co₃O₄ nanofiber network and the hydrophilic functional groups provided by PSS. This hybrid nanostructure provides an efficient platform for water molecule interaction, enabling robust humidity detection.
This work demonstrates that Poly(sodium 4-styrenesulfonate) is an effective surface modifier for ceramic nanomaterials, offering a cost-effective strategy to design advanced room-temperature humidity sensors with excellent performance metrics.
