Abstract
Biosorption of thorium by Epicoccum nigrum biomass was determined at varying experimental conditions using a batch technique. High biosorption efficiency was observed for dead biomass 500 mg/50 mL of E. nigrum within 60 min of contact, at pH 6.8, temperature of 30 ℃ and agitation speed of 150 rpm with 150 mg/L as initial thorium concentration.
Highlights
There are many methods used for recovering metal ions from pregnant solution such as chemical precipitation, ion exchange, solvent extraction and sorption [1]
This paper reports a novel approach for the modification of the surface area of the fungal by ferric chloride nanoparticles to be used in the uptake of thorium by dead biomass of the filamentous fungus E. nigrum
Dead biomass of the fungus E. nigrum was found to be an efficient tool for the uptake of thorium metal ions from aqueous solution
Summary
There are many methods used for recovering metal ions from pregnant solution such as chemical precipitation, ion exchange, solvent extraction and sorption [1]. These traditional techniques suffer from several disadvantages, such as high consumption of reagent and energy, high operational cost, low selectivity and generation of secondary pollutants [2]. The fungus-mediated green technology approach towards the biosorption of metal has several advantages, such as easy and simple scaling up, easy processing, economic viability, biomass handling, and recovery of large surface areas with optimum growth of mycelia [4]. Easy techniques were developed to desorb contaminants from the dead biomass and reuse them [5]
