Biosorption performance evaluation of azo dyes Reactive Red 2 and Reactive Blue 4 on thermally sterilized biomass of Cladosporium tenuissimum fungus

“…These results indicate that the biosorption process of RDR2 and RDB4 onto sterilized biomass of C. tenuissimum in the three temperatures assayed follows a kinetics of pseudo-second-order. The pseudo-second-order model assumes that the adsorption rate is proportional at the square of the difference between the amount of adsorbate in the adsorbent surface in the time and the maximum amount of adsorbate that can be adsorbed on the surface, and this model has been used to explain chemisorption phenomenon (Lavado-Meza et al, 2021). Similar results where the model of pseudosecond-order described kinetically the bisorption of RDR2 and RDB4 onto several biomaterials such as the Agaricus bisporus biomass, Rhizopus oryzae biomass, chitosan and anaerobic sludge of textile wastewater have been observed (Akar and Divriklioglu, 2010;Bagchi et al, 2021;Karmaker et al, 2020;Sonai et al, 2016).…”
