Special Issue Information

Dear Colleagues,

Nano- and microdispersed systems can be defined as dispersions of nano- and microparticles (droplets, bubbles) of one material within a continuous phase of another material (gas, liquid, solid). Such systems are very widespread in nature. The most common examples include soils, aerosols, minerals, and various natural colloids. Nano- and microdispersed systems are also the subject of active research and represent a techno-economic sector with full expansion in many application domains. Nano- and microdispersed systems have gained prominence in technological advancements due to their diverse physicochemical and mechanical properties, including wettability, dispersion stability, electrical and thermal conductivity, catalytic activity, resulting in enhanced performance over their counterparts with particle size above 1 µm. Such systems are of interest to various research areas, including the development of new polymers and ceramic composites, sensors, biomaterials, energy conversion devices, wastewater treatment strategies, and many other applications.

The present Special Issue of Processes will include recent enhancements in the synthesis and application of various types of nano- and microdispersed systems and will help to expand scientific cooperation in this important field of research.

The reduction of heavy and radioactive metal pollution of industrial wastewater remains a vital challenge. Due to layered structure and developed surface, potassium polytitanate had potential in becoming an effective sorbent for metal extraction from wastewater in the presented paper. On the basis of the different sorption models, this paper studied the mechanism of Pb2+ and Sr2+ cation extraction from aqueous solution by non-crystalline potassium polytitanate produced by molten salt synthesis. The ion exchange during metal extraction from model solutions was proven by kinetic analysis of ion concentration change, electronic microscopy, and X-ray fluorescence analysis of sorbent before and after sorption, as well as by theoretical modeling of potassium, lead, and strontium polytitanates. The sorption was limited by the inner diffusion in the potassium polytitanate (PPT) interlayer space, as was shown using the Boyd diffusion model. The sorption processes can be described by Ho and McKay’s pseudo-second-order model compared to the Lagergren pseudo-first-order model according to kinetic analysis. It was found that the ultimate sorption capacity of synthesized sorbent reached about 714.3 and 344.8 (ions mg/sorbent grams) for Pb2+ and Sr2+ ions, respectively, which was up to four times higher than sorption capacity of the well-known analogues. Therefore, the presented study showed that potassium polytitanate can be considered as a promising product for industry-scaled wastewater purification in practice. Full article
