“…A similar behaviour of percentage degradation (60.21%) was observed under alkaline conditions (pH = 11) after 60 min. 23 The formation of the Ti 4+ was suppressed under extremely acidic conditions (pH = 03). This resulted in the inhibition of radical formation.…”

“…This was due to the self-quenching phenomenon of the catalyst. 24 An excessive amount of catalyst inhibited light absorption by the whole sample. Moreover, the excess dose of Bi 85 Ca 15 Fe 85 Ti 15 O 3 photocatalyst could result in agglomeration, which could decrease the photocatalyst-antibiotic interaction.…”

“…For this reason, tertiary treatment is required. Filtration techniques such as reverse osmosis (RO) or advanced oxidation processes (AOPs) (e.g., degradation of methylene blue under visible [ 10 ] and UV light [ 11 ]) are, then, employed for this scope. However, the former technique produces an undesired concentrated sludge/brine that should be further processed in order to avoid environmental concerns due to its disposal [ 12 , 13 ]; while the latter require severe control of the working conditions (e.g., pH) to achieve a complete mineralization/degradation of the target compounds [ 5 ].…”

Removal of Methylene Blue from Wastewater by Waste Roots from the Arsenic-Hyperaccumulator Pteris vittata: Fixed Bed Adsorption Kinetics

et al. 2023

Phytoremediation of arsenic-contaminated water was successfully conducted by means of the perennial fern Pteris vittate, which is an arsenic-hyperaccumulator plant able to grow in hydroponic cultures. In order to avoid the costs linked to the disposal of As-contaminated biomass, in this work, Pteris vittata waste roots were tested as a low-cost bio-adsorbent for the removal of methylene blue (MB) from water in a fixed-bed adsorption configuration. As a matter of fact, methylene blue can negatively impact the growth and health of algae and plants by blocking light from reaching them in water, which can alter their normal biological processes. Previous works have already shown the potentiality of such material toward the uptake of methylene blue; however, all the studies conducted were just focused on batch-mode experiments. In this work, column runs were carried out at 20 °C, evaluating the bed void fraction for each test and hence estimating the apparent density of the material (300 g/L). The breakthrough curves collected were fitted by means of a mathematical model based on the linear driving force (LDF) approximation to obtain information on the mass transfer mechanism occurring in the system. A relation for the product between the LDF mass transfer coefficient and the solid specific surface (kLDFas) with respect to the Reynolds (Re) dimensionless number was obtained (kLDFas=0.45Re). The range of validity of such expression was Re<0.025. Its applicability was deeply discussed: in such conditions, the technology is ready to be tested at larger scales.

“…In response to large molecules like SDBS, such as organic dyes, both adsorption 9–12 and composite photodegradation methods 13–15 have been investigated. The same approaches have also been applied in SDBS removal research.…”
