Plate column biosorption of Cu(II) on membrane-type biosorbent (MBS) of Penicillium biomass: Optimization using statistical design methods

- A low cost membrane-type biosorbent (MBS) of Penicillium biomass was prepared.
- MBS was piled into a plate column reactor layer and layer for Cu(II) biosorption.
- A set of statistical design methods were employed for Cu(II) removal optimization.
- A quadratic regression model was established with the error less than 1.22%.
- MBS could be reused for 10 cycles without obvious loss of its adsorption ability.
