“…[47][48][49] was longer than that found in this work. The equilibrium time between platinum or palladium and moss biomass was comparable [21] but this time was much longer for other biomaterials (in the range 24-96 h) [17,20,22]. In practice, a sorbent with a faster uptake is better for the removal of metals.…”

The emission of platinum group metals from different sources has caused elevated concentrations of platinum and palladium in samples of airborne particulate matter, soil, surface waters and sewage sludge. The ability of biomass of Aspergillus sp. and yeast Saccharomyces sp. for removal of Pt(IV) and Pd(II) from environmental samples was studied in this work. The pH of the solution, the mass of biosorbent, and contact time were optimized. The Langmuir and Freundlich adsorption isotherms and kinetic results were used for interpretation of the process equilibrium of Pt(IV) and Pd(II) on both microorganisms. The maximal efficiency of retention of Pt(IV) on yeast and fungi was obtained at acidic solutions (pH 2.0 for Pt(IV) and pH 2.5–3.5 for Pd(II)). The equilibrium of the biosorption process was attained within 45 min. The best interpretation for the experimental data was given by the Langmuir isotherm. Kinetics of the Pt and Pd adsorption process suit well the pseudo-second-order kinetics model. Fungi Aspergillus sp. shows higher adsorption capacity for both metals than yeast Saccharomyces sp. The maximum adsorption capacity of fungi was 5.49 mg g−1 for Pt(IV) and 4.28 mg g−1 for Pd(II). The fungi possess the ability for efficient removal of studied ions from different wastewater samples (sewage and road run-off water). It was also demonstrated, that quantitative recovery of Pd from industrial wastes could be obtained by biosorption using Aspergillus sp.

“…A large number of biomaterials such as algae, fungi, bacteria, yeast, biopolymers, and bio‐waste have been used for Pd(II) sorption and recovery . Some of the reported potential biosorbents for sorption of Pd(II) used in the past decade include sulfate‐reducing bacteria, Chlorella vulgaris , Saccharomyces cerevisiae , L‐lysine modified chitosan resin, Racomitrium lanuginosum , chemically modified cedar wood powder, polyallylamine hydrochloride‐modified Escherichia coli , polyethylenimine modified Corynebacterium glutamicum , anaerobic bacterial community, and acid treated Escherichia coli . The use of microbial biomass suffers from drawbacks such as difficulties in solid–liquid separation owing to small particle size, low density, poor mechanical strength, and low reusability, whereas some chemically modified biomass makes use of expensive chemicals.…”

BACKGROUND Naturally available biomass can be explored as a potential sorbent for recovery of precious metals. This work evaluates the sorption potential of a biosorbent developed by host soluble tannins cross‐linked Lagerstroemia speciosa leaves powder (TLS) for Pd recovery from secondary waste. RESULTS Batch experiments suggest 95% Pd(II) sorption by TLS is achieved over a pH range of 1–6 with a maximum of 99% at pH 2. The experimental data for Pd(II) sorption onto TLS is well explained by pseudo‐second‐order kinetics and the Langmuir isotherm model with a monolayer sorption capacity of 46.3 mg g−1. Thermodynamic variables indicate that Pd(II) sorption onto TLS is spontaneous, endothermic, and physical in nature. TLS biosorbent was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, and X‐ray photoelectron spectroscopy (XPS). XPS results reveal the presence of zero‐valent Pd and mono or divalent Pd species on the TLS surface, which conclude that Pd(II) removal is governed by a sorption‐reduction mechanism. CONCLUSIONS The TLS is effective in Pd(II) recovery from an acid‐leached solution of monolithic ceramic capacitors (A‐MLCC) and simulated spent automobile catalyst (A‐SSAC), which suggests that this biosorbent can be used as a promising material in biotechnological processes for recovery of precious metals from secondary waste. © 2016 Society of Chemical Industry

The potential of metal sorption by certain types of biomass provides the basis for the development of a new approach to remove heavy metals when they are present at low concentration. Seaweeds, fungi, yeast, bacteria and other native biomaterials, such as industrial and agricultural wastes and compounds derived from plant and animal tissues (e.g. lignin, tannin, chitin and chitosan), can be used as metal sorbents. The literature review shows that in the case of biomaterials of plant and animal origin mainly basic investigation on the biosorption mechanism, kinetics and thermodynamics of biosorption process using standard solutions of platinum group elements was described. For the recovery of these metals from real effluents and waste materials different types of microorganisms were applied. Due to good sorption performance and high selectivity, microorganisms were also used in analytical application for the separation and preconcentration of metals from interfering matrix before their determination by spectrometric techniques. In this book chapter the employment of biosorption processes for removal/recovery of platinum, palladium and rhodium from wastes and the procedures of their determination in environmental samples using biosorption process and different detection techniques are presented and discussed.
