Continuous fixed-bed biosorption process: A review

Chemical Engineering Journal Advances, Journal Year: 2021, Volume and Issue: 8, P. 100188 - 100188

Published: Sept. 24, 2021

Biosorption is one of the solute enrichment techniques driven by concentration difference biosorbate molecules among bulk liquid phase and solid biosorbent. The presence surface functional groups biosorbents facilitates formation physical/chemical interactions with biosorbates at solid-liquid interface. proved as an alternative, effective sustainable approach to traditional water treatment technologies. Abundance, biodegradable, versatile functionalities, ease tailor-made modifications have fascinated many researchers exploit their potential in removal a wide range pollutants batch/continuous mode operation. However, reports on continuous biosorption are significantly lesser hence, present review focused only fixed-bed comprehensively discussed vital shortcomings current research. Conclusively, this recommends research hotspots for scientific community address prevailing gaps.

A meta-analysis of metal biosorption by suspended bacteria from three phyla

Chemosphere, Journal Year: 2020, Volume and Issue: 268, P. 129290 - 129290

Published: Dec. 11, 2020

Biosorption of heavy metals by bacterial biomass has been the subject significant research interest in last decades due to its efficiency, relatively low cost and minimal negative effects for surrounding environment. In this meta-analysis, biosorption efficiencies different strains Cu(II), Cd(II), Zn(II), Cr(III), Mn(II), Pb(II) Ni(II) were evaluated. Optimum conditions process such as initial metal concentration, temperature, pH, contact time, type, dosage phyla, evaluated each metal. According results, removal follows: Cd(II) > Cr(III) Zn(II) Cu(II) Mn(II). Firmicute phyla showed highest overall (living dead) efficiency metals. Living Proteobacteria had best performance. was significantly more efficient than dead biomass. The maximum achieved at pH values between 6 7.5. High temperatures (>35 °C) reduced increased ions. non-essential occurred with short times (<2 h). Essential Zn Cu efficiently removed long durations (>24 mean capacity 71.26 125.88 mg g−1. No publication bias existed according Egger's Begg's test results.

Recent trends in Ni(II) sorption from aqueous solutions using natural materials

Reviews in Environmental Science and Bio/Technology, Journal Year: 2021, Volume and Issue: 21(1), P. 105 - 138

Published: Dec. 5, 2021

Abstract The use of materials natural origin for the adsorption heavy metal ions from aqueous solutions has gained attention in recent years among scientific community. This is explained by fact that nickel compounds, due to severe health consequences, are considered be most dangerous environment. article reviews results studies on biosorbents purification ions, and then attempts classify them according their origin. characteristics sorption capacity have been compared, removal mechanisms identified which chemisorption ion exchange common. From analyses, a major trend biomass; however, other groups also continue attract interest researchers. Conducting laboratory can help select with high efficiency. highest values each group were: waste products 56 mg Ni·g −1 (olive stone), peat 61 , miscellaneous 225 (microbial flocculant GA1), biomass 286 ( Plantanus orientalis bark) composites/modified calcinated eggshells 769 (calcinated eggshells). However, some phenomenon may accompanied precipitation presence hydroxides, significantly affects achieved. There need transfer these experiments an industrial scale so as verify applicability. In such applications, should paid not only effectiveness material, but its availability, price, ease use, well effect biosorbent terms changing quality parameters aquatic

Study on the Mechanism by Which Fe3+ Promotes Toluene Degradation by Rhodococcus sp. TG-1

Microorganisms, Journal Year: 2025, Volume and Issue: 13(2), P. 468 - 468

Published: Feb. 19, 2025

Volatile organic compound pollution caused by toluene has become a global issue. In order to solve this problem, biodegradation of been applied all over the world. This study investigated effects Fe3+ on degradation Rhodococcus sp. TG-1. The results show that 1 mg L−1 increased rate 600 from 61.9% 87.2% at 16 h. acceleration mechanism was explicated using transmission electron microscope (TEM) and energy-dispersive X-ray spectroscopy (EDX) analyses, coupled plasma optical emission spectroscopy, an enzyme activity assay, transcriptome analysis. Four genes were detected be significantly up-regulated under induction, suggesting might implicated in degradation. Meanwhile, component active center catechol 1,2-dioxygenase (C12O) improved C12O. which accelerates proposed based transcription levels provided method for enhancing effect furthered our comprehension
