S. cerevisiaecells modified with nZVI: a novel magnetic biosorbent for nickel removal from aqueous solutions

Simultaneous Removal of Metal Ions from Wastewater by a Greener Approach

“…The q max value was found to be 90.09 mg/g for Pb(II), which was higher than that of P. chrysosporium-treated wastewater [59], a bioreactor biosorption system [42], and ethanol-treated S. cerevisiae [47], but less than that of EDTA-treated yeast [60]. The q max was estimated to be 51.55 mg/g for Ni(II), which was near the value estimated by Guler and Ersan [61], and was higher the value Özer and Özer [33] and Guler and Sarioglu [62]. The q max for the prepared yeast was higher and lower, respectively, than the q max found in the literature, probably attributed to the condition of the reaction, the treatment materials, the source of yeast, the media used to culture the yeast, and the inactivation.…”

“…In addition, the value of 1/n < 1 calculated from the Freundlich isotherm model confirms that the process is chemical [57]. Table 3 presents a comparison of the qmax obtained from the Langmuir isotherm model in the literature data [33,42,47,[58][59][60][61][62] with this investigation for various adsorbents The highest biosorption capacity (q max ) for Cd(II), Pb(II), and Ni(II) ions is 65, 90, and 51 mg/g, respectively. The fundamental isothermal characteristics of Langmuir's are evident in expressions of RL (a dimensionless constant separation factor), known as RL = 1 (1+bC 0 ) in the range 0 < RL < 1, reflecting the appropriate adsorption process [56].…”

“…Table 3 presents a comparison of the q max obtained from the Langmuir isotherm model in the literature data [33,42,47,[58][59][60][61][62] with this investigation for various adsorbents to Cd(II), Pb(II), and Ni(II). The q max value for Cd(II) was found to be 65.36, which was higher than that of B. thuringiensis-remediated wastewater [58], ethanol-treated yeast [47], and EDTAtreated yeast [60].…”
