dc.description.abstract	Biosorption of Cu(II) ion by Aspergilus niger were investigated in a batch system. The capacity of Aspergilus niger to remove Cu(II) ion from aqueous solution were investigated under varying parameters which include: initial metal concentration, temperature and inoculum concerntration on biosorption capacity were also studied. The maximum biosorption capacity of Aspergilus niger was at 25 ppm of Cu(II), showed 100 % removal at pH 5.8 and 25 oC. Biosorption equilibrium was established in 150 minutes. The process fitted well into pseudo second order kinetic model and was best explained by Langmuir isotherm with maximum absorption capacity of 6.998 mgL-1. The values of thermodynamic parameters obtained from this study, (i.e. ∆Go, ∆Ho and ∆S◦ values) imply that the process is feasible and spontaneous.
