Characterization of iron-modified natural clay for textile dye retention by sono-adsorption technology

Synergistic sono-adsorption and adsorption-enhanced sonochemical degradation of dyes in water by additive manufactured PVDF-based materials

“…In this regard, ultrasound-assisted adsorption and desorption has been known for a while; some early work on this topic were published over two decades ago [68] , [69] . However, the effect of ultrasound on adsorption processes did not receive much attention until recent years, where the number of publications on sono-adsorption for environmental remediation applications has flourished [42] , [43] , [70] , [71] , [72] , [73] , [74] , [75] , [76] , [77] , [78] . In all of these studies, though, experimental sono-adsorption data was routinely fitted to empirical models such as pseudo-first order adsorption kinetics, pseudo-second order adsorption kinetics, Elovich chemisorption kinetics and intraparticle diffusion that may lead to the incorrect interpretation of the mass transport mechanisms behind the overall adsorption process [56] .…”
