“…Top-down methods such as high energy ball milling are very effective alternatives that have been used for size reduction other water treatment materials such as nano-zero valent iron [27,28] and calcite [29]. Ultra-sonication is another top-down size reduction method able to produce microparticles and nanoparticles directly from some soft bulk material as hematitic/goethitic iron ore fines [30], talc [31], or TiO 2 [32]. Milling and ultra-sonication methods have the advantage that the chemistry of the particles will not be altered, hence bulk and particle adsorbents could be more directly comparable.…”

Ball milling and ultra-sonication size reduction procedures were applied to granular ferric hydroxide (GFH) to obtain two micro-sized adsorbents. These two adsorbents and GFH were investigated to improve the removal of phosphates from water. The size reduction procedures, using the milling method, allowed a reduction of size from 0.5–2 mm to 0.1–2 µm and total disaggregation of the GFH structure. Using an ultra-sonication method yielded a final size of 1.9–50.3 µm with partial disaggregation. The Langmuir model correlated well with the isotherms obtained in batch equilibrium tests for the three adsorbents. The maximum adsorption capacity (qmax) for the milled adsorbent was lower than GFH, but using ultra-sonication was not different from GFH. The equilibrium adsorption of two wastewater samples with phosphate and other anions onto the GFH corresponded well with the expected removal, showing that potential interferences in the isotherms were not important. Batch kinetics tests indicated that the pseudo second-order model fitted the data. Long-term adsorption capacity in kinetics (qe) showed the same trend described for qmax. The application of milling and ultra-sonication methods showed 3.5- and 5.6-fold increases of the kinetic constant (k2) versus the GFH value, respectively. These results showed that ultra-sonication is a very good procedure to increase the adsorption rate of phosphate, maintaining qe and increasing k2.

“…[ 4 ] Although other mechanical energy forms, including sonication and grinding or milling, are effective in materials processing, they suffer from indiscriminate events in time and place, such as in cavitation and uneven energy transfer, resulting in nonuniform products under nonoptimised processing conditions. [ 5 ] This can generate waste that, coupled with high energy usage, limits the sustainability metrics of such processing. A paradigm shift in microfluidics design is required to overcome such limits.…”

Centrifugal and shear forces are produced when solids or liquids rotate. Rotary systems and devices that use these forces, such as dynamic thin‐film flow technology, are evolving continuously, improve material structure‐property relationships at the nanoscale, representing a rapidly thriving and expanding field of research high with green chemistry metrics, consolidated at the inception of science. The vortex fluidic device (VFD) provides many advantages over conventional batch processing, with fluidic waves causing high shear and producing large surface areas for micro‐mixing as well as rapid mass and heat transfer, enabling reactions beyond diffusion control. Combining these abilities allows for a green and innovative approach to altering materials for various research and industry applications by controlling small‐scale flows and regulating molecular and macromolecular chemical reactivity, self‐organization phenomena, and the synthesis of novel materials. This review highlights the aptitude of the VFD as clean technology, with an increase in efficiency for a diversity of top‐down, bottom‐up, and novel material transformations which benefit from effective vortex‐based processing to control material structure‐property relationships.
