Natural polymers have proven to be extremely interesting matrices for the immobilization of microbial biomasses, via various mechanisms, in order to bring them into a form easier to handle—the form of composites. This article aimed to study composites based on a residual microbial biomass immobilized in sodium alginate via an encapsulation technique as materials with adsorbent properties. Thus, this study focused on the residual biomass resulting from beer production (Saccharomyces pastorianus yeast, separated after the biosynthesis process by centrifugation and dried at 80 °C)—an important source of valuable compounds, used either as a raw material or for transformation into final products with added value. Thus, the biosorptive potential of this type of composite was tested—presenting in the form of spherical microcapsules 900 and 1500 μm in diameter—in a biosorption process applied to aqueous solutions containing the reactive dye Brilliant Red HE-3B (16.88–174.08 mg/L), studied in a batch system. The preparation and characterization of the obtained polymeric composites (pHPZC, SEM, EDS and FTIR spectra) and an analysis of different equilibrium isotherms (Langmuir, Freundlich and Dubinin-Radushkevich—D–R) were investigated in order to estimate the quantitative characteristic parameters of the biosorption process, its thermal effects, and its possible mechanisms of action. The modelling of the experimental data led to the conclusion that the studied biosorption process took place after reaching the Langmuir isotherm (LI), and that the main mechanism was possibly physical, being spontaneous and probably exothermic according to the values obtained for the free energy of biosorption (E = 8.45–13.608 kJ/mol, from the DR equation), as well as the negative values for the Gibbs free energy and the enthalpy of biosorption (ΔH0 = −87.795 kJ/mol). The results obtained lead to the conclusion that encapsulation of this residual microbial biomass in sodium alginate leads to an easier-to-handle form of biomass, thus being an efficient biosorbent for static or dynamic operating systems for effluents containing moderate concentrations of reactive organic dyes.

“…Maximum absorbance wavelength for dyes like Congo red, Crystal violet, Malachite green, Methyl red and Methylene blue is 498nm, 590nm, 617nm, 425nm and 668nm respectively [14][15][16][17][18]. In the UV-Vis spectra (Figure 3-7), a significant reduction has been observed in the absorbance values at these wavelengths for each specific dye in non-blank solutions as given in Table 1.…”

Present work deals with the synthesis of magnetic Nickel-Cobalt spinel ferrite [Ni0.5Co0.5Fe2O4] nanoparticles using combustion method, and adsorption of different dyes using synthesized ferrite material. Synthesized ferrite material has been characterized by using FTIR spectroscopy. Nickel-Cobalt ferrite material has worked very efficiently as an adsorbent and can absorb different dyes from their aqueous solutions. Its magnetic nature gives a fair chance to extract it back from the solutions, by applying magnetic field. Extracted ferrite materials don’t lose its potency to adsorb. Hence, it can be used in number of wastewater treatment cycles. Adsorption capacity and reusability of these ferrite materials make them suitable for future alternate adsorbents in the field of wastewater treatment.
