This work investigated cadmium ions biosorption on Fish scales (FS) of Sardina pilchardus. Different relevant parameters such as initial pH in the range 2.14–7.76, concentration from 35 to 150 mg L?1, and biosorbent dose 50–300 were examined. The effect these removal was analyzed optimized using full factorial design methodology analysis variance. kinetics modelized for pseudo-second order pseu...

The paper discusses various aspects of biosorption of microelements by marine seaweeds to be used as mineral feed supplement for livestock. n the study, biosorptive properties of a single marine species Cladophora rupestris and mixed species of algae from the Baltic Sea (a mixture f Cladophora sp. and Enteromorpha prolifera) were investigated. The mechanism of biosorption was identified as cati...

The study involves the batch biosorption process for the removal of Chromium in the aqueous solution using the dried pods of Prosopis spicigera. Factors influencing the biosorption are pH, contact time, adsorbent dose and initial metal ion concentration. Characterization of the biosorbent is carried out to study the morphology by using Scanning Electron Micrograph (SEM). The maximum biosorption...

Over the past 25 years, intensifying research into metal biosorption elucidated the principles of this effective metal-concentration phenomenon. Biosorption can be cost-effective particularly in environmental applications where low costs of the metal removal process are most desirable. Some efficient natural biosorbents have been identified that require little modification in their preparation....

BACKGROUND Ceriporia lacerata, a strain of white-rot fungus isolated from the litter of an invasive plant (Solidago canadensis) in China, was little known about its properties and utilization. In this work, the copper(II) biosorption characteristics of formaldehyde inactivated C. lacerata biomass were examined as a function of initial pH, initial copper(II) concentration and contact time, and t...

Mycotoxin adsorption onto biomaterials is considered as a promising alternative for decontamination without harmful chemicals. In this research, the adsorption of B-aflatoxins (AFB₁ and AFB₂) using Pyracantha koidzumii biomasses (leaves, berries and the mixture of leaves/berries) from aqueous solutions was explored. The biosorbent was used at 0.5% (w/v) in samples spiked with 100 ng/mL of B-afl...

Recently, increased interest in the application of various biosorbents in metal ions removal has been observed. The paper presents a systematic characterization of new and commonly abundant low-cost biosorbents: above-ground plant parts of wheat straw and grass. Cr(III) was chosen as a model sorbate. The effect of the most significant process parameters (temperature, pH, initial concentration o...
