“…for viable biomass, non-viable biomass, HNO 3 treated biomass and NaOH treated biomass, respectively. These values are higher than for many fungal biomasses such as, Aspergillus niger (Vale et al 2016), Penicillium chrysogenum (Tan, Cheng 2003), but lower than for Rhizopus arrhizus (Kapoor, Viraraghavan 1995) and Streptoverticillium cinnamoneum (Puranik, Paknikar 1997). …”

“…The NaOH treated biomass showed highest detoxification of Zn 2+ at pH 8, with a value of 9.11 ± 0.04 mg g -1 dry mass. Many studies have shown that pH is an important factor affecting biosorption of Zn 2+ (Vale et al 2016;Vaishnav et al 2012;Javaid et al 2011). The solution pH influences the adsorbent surface charge.…”

The purpose of this research was to estimate the Zn 2+ biosorption by biomass of Humicola phialophoroides fungus isolated from creek sediments in a zinc mine area in Thailand. The Langmuir isotherm model gave a better fit for the result data more than Freundlich, Temkin and Dubinin-Radushkevich isotherm models. Zn 2+ removal ability in all H. phialophoroides biomass types as increasing Zn 2+ concentration had the same pattern, but biomass pretreated by NaOH showed better Zn 2+ removal ability than viable biomass, nonviable biomass, and HNO 3 pretreated biomass. Maximum Zn 2+ biosorption of biomass pretreated with NaOH took place at initial solution at pH 8 after 150 min. In addition, Zn 2+ was well adsorped by NaOH pretreated biomass at temperature higher than 70 °C, while desorption experiments indicated that the desorption efficiency with 0.1 M HNO 3 solution reached 92.31%.

“…An alternative explanation might be the structural alteration of the sorbent surface in acidic environment and consequent loss of sorption capacity [33][34][35]. A third mechanism possibly contributing to reduce Cr(VI) sorption at low pH (<2) might be the formation of oligomers of chromium species such as Cr3O10 2− and Cr4O13 2− [36,37].…”

“…The sorbent affinity toward Cr(VI) can be evaluated from the Langmuir equilibrium constant (K L ): the higher K L the higher the sorbent affinity for Cr(VI). Among tested sorbents (Table 1), Sargassum bevanom (K L = 1160 L mmol −1 ) [19] and Aspergillus niger (K L = 1140 L mmol −1 ) [37] exhibit the highest affinity for Cr(VI), followed by L-cysteine functionalized magnetite (K L = 215 L mmol −1 ) [10], magnetic ion exchange resin (K L = 181 L mmol −1 ) [38] and calcinated Al/Fe oxide-oxyhydroxide composite (K L = 123 L mmol −1 ) [67]. For practical purposes, it is also relevant to evaluate sorbent affinity at low Cr(VI) initial concentration.…”

Cr(VI) Sorption from Aqueous Solution: A Review

et al. 2020

Hexavalent chromium (Cr(VI)) in water systems is a major hazard for living organisms, including humans. The most popular technology currently used to remove Cr(VI) from polluted water is sorption for its effectiveness, ease of use, low cost and environmental friendliness. The electrostatic interactions between chromium species and the sorbent matrix are the main determinants of Cr(VI) sorption. The pH plays a central role in the process by affecting chromium speciation and the net charge on sorbent surface. In most cases, Cr(VI) sorption is an endothermic process whose kinetics is satisfactorily described by the pseudo second-order model. A critical survey of the recent literature, however, reveals that the thermodynamic and kinetic parameters reported for Cr(VI) sorption are often incorrect and/or erroneously interpreted.
