Many investigations have demonstrated that polymers modified using carbonaceous materials such as biochar, could be effectively employed for heavy metal removal. In this study, pectin, cellulose, and SDS were mixed and modified using cocopeat biochar to synthesise composite beads with increased adsorption capabilities. Through the use of Response Surface Methodology, we could achieve highly efficient adsorption of copper ions, reaching a maximum adsorption capacity of 568.17 mg/g with a minimum dosage of 0.6 g/L within just 1.5 h. To evaluate the microstructure and mechanism of adsorption, we performed various characterisation techniques on air-dried and freeze-dried beads in both pre-and post-adsorption states in single and multi-metal systems. Cu was recovered from the beads using 0.4 M sulphuric acid, with an efficiency of 99.97 %. The beads demonstrated reusability for Cu ions up to 5 cycles and may thus be regarded as a cost-effective and efficient bio-sorbent for removing copper.
