Size selectivity in adsorption of polydisperse starches on activated carbon

Ultrasonic-assisted activated carbon separation removing bacterial endotoxin from salvia miltiorrhizae injection

“…It is frequently used for the removal and decolorization of hazardous compounds. To assure the safety of the clinical usage of the injection, activated carbon is frequently employed as an adsorbent in the manufacturing process to efficiently adsorb pyrogen in the drug solution, increase the safety of the injection, and effectively improve the clarity of the preparation [4] , [5] , [6] . However, as activated carbon lacks the unique property of pyrogen adsorption and instead primarily uses the van der Waals force to adsorb pyrogen and other compounds to carbon chains, it will result in the loss of pharmaceutical components during the adsorption process [7] .…”

Greener starch oxidation : Exploring challenges in designing catalytic processes for polydisperse feedstocks

“…Adsorption and desorption studies are common in catalyst design, however, polydispersity in substrates introduces an additional variable to this testing (Hoogstad et al, 2023). The final step in the flowchart of testing the catalyst and iterating the design includes activity, selectivity, and stability testing among other traditional design elements in this stage.…”

“…Moreover, in these studies the effect of molecular weight distributions were not quantified. Molecular weight distributions have been shown to have an effect on processes with polydisperse and macromolecular substrates (Hoogstad, Kiewidt, van Haasterecht, & Bitter, 2023; but is often not considered. The knowledge gap on quantitative diffusion of macromolecules (>10nm) and the effect of molecular weight distributions is also recognized as a major point of improvement for the field in the work of (Li et al, 2023) on the potential of heterogeneously catalysed depolymerisation of lignin.…”
