| description | Chemical
industry wastewater containing metals must be treated so as not to threaten the
environment or human life. One of the wastewater treatments is the biosorption
process using living microalgae. Although living microalgae can provide better
results as a biosorbent, the mechanism of this biosorption process is complex
because it involves two steps of the process, active and passive uptake, which
run simultaneously. In addition, several process parameters need to be adjusted
for the biosorption process to operate optimally. This study aims to
investigate the effect of several parameters such as microalgae concentration,
salinity, and light color. Synthetic CuSO4 solution at a
concentration of 40 mg/L and pH 5 is used as artificial waste, while microalgae
Chlorella sp. is used as biosorbent. The biosorption process was
operated in a batch system at room temperature for 6 days. The experimental
results show that 96.83% of the Cu(II) ions could be removed when the
microalgae concentration, salinity, and light color were conditioned at 1.5 x
106 cells/mL, 3,000 mg/L, and red light, respectively. |
