| Abstract | The contamination of heavy metals in wastewater that has extremely low pH, is over the standard limit for heavy metals (Pb and Cr), and has a high amount of total dissolved solids (TDS) is a serious problem in lead-acid battery manufacturing. Various studies have shown that biosorption is an effective and economical technology for removing heavy metals. In this study, Cr (III) and Ni (II) adsorption of cuttlebone powder (CB) was tested, and CB was applied to treat wastewater generated by lead-acid battery manufacturing. The Cr (III) adsorption of CB was optimum in an initial pH of 6.0 using CB 0.4 g/L; in addition, Ni (II) adsorption was optimum in an initial pH of 3.0 using CB 0.2 g/L. The adsorption kinetic was suitable, as it demonstrated a high correlation coefficient (R2>0.9) with pseudo-second-order kinetic model. Both Cr (III) and Ni (II) adsorption were in equilibrium in 20 minutes. By Langmuir isotherm (R2>0.9), the maximum adsorption capacity of CB was 555.55 mg/g in Cr (III) adsorption and 78.74 mg/g in Ni (II). CB was an effective biosorbent, pH neutralizer, and heavy metal remover. On the laboratory scale, lead-acid battery wastewater was successfully treated into the industrial effluent standard limit using a combination of Ca(OH)2 pre-treatment and CB. |
