Characterization and properties of Pleurotus mutilus fungal biomass as adsorbent of the removal of uranium(VI) from uranium leachate

Amidoxime functionalized Trametes trogii pellets for removal of uranium(VI) from aqueous medium

“…Biosorption is not only cost effective, but it also provides an opportunity for the recycling of waste materials [15,16]. A variety of low cost fungal materials (native and modified) have been used as biosorbents for the removal of organic pollutants and heavy metal ions from aqueous solutions, including Lentinus sajor-caju [3,[17][18][19], Trametes versicolor [6], Aspergillus niger [14,20], and Lentinus edodes [21][22][23][24][25]. Additionally, uranium biosorption by various microbial biomasses (i.e., fungi, yeast, algae, and unicellular bacteria) are reported in the literature [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Characterization, kinetics and thermodynamics of biosynthesized uranium nanoparticles (UNPs)

“…The extracellular protein production increased with shaking and becomes 0.420 lg/ml while its value is 0.400 lg/ ml with static condition. Mezaguer et al [26] proved that the uranium adsorption capacity varies in the same order with the stirring speed and the maximum sorption capacity was found at a stirring speed 315 rpm. The author suggested that the increase in the stirring speed favors the diffusion of uranium into the boundary layer adsorption, which becomes very thin and the diffusion coefficient of adsorbed species increases.…”

Removal of As(V) from wastewater by chemically modified biomass

“…The FTIR spectrum of pristine biomass shows predominant bands at 3500-3200 cm −1 (Bonded hydroxyl OH of water and R-NH 2 ), 2930-2857 cm −1 (-CH stretching vibration in -CH and -CH 2 ), 1735 cm − 1 (NC_O stretching of the protonated carboxylic or ester groups or fatty acids), 1710 cm −1 (C_O of the carboxylic groups in amino acids), 1655 and 1556 cm −1 (C_O stretching and N-H stretching vibration in amide bond respectively), 1320 cm − 1 (S_O of the sulfonates groups and COO − groups of the fatty acids), and 1043 cm −1 (-CO stretching vibration in -COH). The phosphate group also presents certain characteristic absorption peaks (P_O stretching at 1150 cm −1 , P-OH stretching at 1040-910 cm −1 , and P-O-C stretching at 1050-970 cm −1 ) [35][36][37]. After the modification with PEI, the amide I (C_O stretching of amides) and II bands (N-H and C_N stretching of amides) [38,39] appeared at 1655 and 1556 cm −1 are shift to 1652 and 1550 cm −1 , respectively.…”
