Biosorpsi Anabaena Cycadae Dengan Variasi Dosis Biosorben, Ukuran Partikel Dan Waktu Kontak Untuk Penyisihan Logam Crom (Cr) Total Dari Limbah Cair Industri Elektroplating

Heavy metal such as chromium (Cr) is waste from electroplating has negative impact to organism because it’s toxic, hard to degrade, and accumulates in the body of exposed organism. Utilization of algae biomass can be an alternative solution to environmental pollution problems due to heavy metals, because it has an active site and pores on the surface so it can be used in biosorption process, can be regenerated, environmentally friendly and the population is quite a lot. This study was conducted to determine whether the biosorbent of Anabaena cicadae algae in reducing Cr level, to determine adsorption capacity and to determine the effect of biosorbent dose, particle size and contact time for Cr removal efficiency of electroplating industry waste water. Biosorbent dose variation are 500 mg / l, 700 mg / l, 900 mg / l and 1100 mg / l, 105μm, 149 μm and 177 μm biosorbent particle size and contact time variations of 30, 45, 60, and 75 minutes were performed to determine the effect to the biosorption process. The optimum state was obtained at an algal dose is 900 mg / l, a particle size is 105 μm with a contact time is 60 min. The highest efficiency value obtained is 74.87%. The adsorption capacity of algae in absorbing Cr metal is 2,379 mg / g. Biosorbent algae that have been saturated after the process of removal of Cr metal then regenerated using 0.1 N HCL as desorption agent. The results of Cr metal removal efficiency after the regeneration is 67.14%
Keywords: biosorption, algae biomass, biosorbent mass, pH, contact time, Cr, electroplating wastewate, regeneration.
