Comparative analysis on equilibrium sorption of metal ions by biosorbent Tempe

This paper reports the biosorption study of Cu 2+, Mn 4+, and Zn 2+ by Rhizopus Oligosporus biomass cultured in Tempe. The maximum adsorption rate occurred at pH 8 and initial concentration of 200 mg/l. The Cu 2+ uptake was in equilibrium at 8 mg/g after 15 min of contact time. The Mn 4+ uptake was...

Description
Summary:This paper reports the biosorption study of Cu 2+, Mn 4+, and Zn 2+ by Rhizopus Oligosporus biomass cultured in Tempe. The maximum adsorption rate occurred at pH 8 and initial concentration of 200 mg/l. The Cu 2+ uptake was in equilibrium at 8 mg/g after 15 min of contact time. The Mn 4+ uptake was at 9 mg/g after 60 min of contact time. The equilibrium adsorption for Zn 2+ was at 12 mg/g after 30 min of contact time.
