Abstract—The potential of Pleurotus ostreatus as biosorbent for cadmium (II) removal was investigated. The maximum cadmium (II) removal was found to be at 85%, under the optimum condition of 0.5 g Pleurotus ostreatus biosorbent concentration, initial pH 6, 10 minutes contact time, 10 mg/L cadmium (II) concentration in 50 mL solution, at 125 rpm on orbital shaker and at room temperature (26 ± 1 °C). The application of Pleurotus ostreatus as biosorbent in electroplating industrial wastewater was also investigated. This study is pivotal for further modeling and scaled up pilot study in alternative sustainable heavy metals removal technology development by deploying Pleurotus ostreatus biosorbent
