Removal of nickel(ii)‎ by penicillium chrysogenum and aspegillus niger biomass

الملخص EN

In this study the biomass used was isolated from a biological sludge collected from a dairy wastewater treatment plant.

Penicillium chrysogenum and Aspergillus niger, were isolated and cultured in our laboratory, dried and ground at 500μm.

The Nickel removal experiments were done in a batch mode on shaken conditions.

The kinetic results at a natural pH revealed that the equilibrium reached after 60 minutes and, the obtained removal capacity was 90 mg / g.

Isotherm studies showed a better removal Nickel with Aspergillus niger (90% uptake).

Furthermore, higher pH values gave a better removal capacity.
