The effects of shaking time, Cu concentration and equilibrium pH on the biosorption of copper ions from aqueous solution were studied. Batch biosorption experiments proved the technical feasibility of using PTL particles to remove copper ions from aqueous sol...

The potential of Bread Fruit (artocarpus altilis)Seed Husk (BFSH) as low-cost biosorbent for the removal of Pb (II), Zn (II) and Co (II) ions from aqueous solution was investigated. The adsorbent was characterized by the Fourier Transform InfraRed (FT-IR)spectroscopy, Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD). The batch methodology was utilized to dete...

A feedforward neural network model with a single hidden layer was used to correlate and predict biosorption equilibrium data in a binary metal system. Experimental data on the biosorption of Fe(III) and Cr(VI) by the microalga Chlorella vulgaris reported in the literature was used to assess the performance of the neural network. It was demonstrated that the neural network approach was significa...

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....

Biosorption of each of the heavy metals, Zn(II) and Cu(II), and of the binary mixture of these two metal ions by the indigenous Thiobacillus thiooxidans was investigated in this study. Equilibrium concentration (qm) and dissociation constant (Kd) were calculated by fitting the experimental data with the Langmuir isotherms. The effects of pH, pretreatment of biomass, and temperature on the amoun...
