Abstract—

The investigation aimed to remove the Pb(II) ions from the artificial liquid using PDAC. In PDAC, PD is an abbreviation of Pithecellobium Dulce, it is a botanical name of Manila Tamarind and AC means Activated Carbon. Pithecellobium Dulce Activated carbon (PDAC) is synthesized from Pithecellobium Dulce bark and pod shell. Lead is used for cables, roofs, water and gas pipelines, mining activities, the manufacturing of acid batteries, and other structures. The industry recognizes the need for dye-treated sewage treatment because it can cause health problems for humans and animals. This research explored PDAC for its possible consumption as an eco-friendly bio-adsorbent to remove the Pb(II) ions. This investigation studied adsorption-related variables, including initial metal ion concentration, contact time, adsorption rate, temperature effects, and pH. Adsorption equilibrium was determined using Longmuir and Friendlich’s isothermal models. Current work suggests that PDAC could be employed as a low-cost adsorbent to adsorb the lead ion in an artificial liquid solution. Adsorption characteristics were determined by SEM, XRD, and FTIR studies. The results of the study demonstrated that employing an environmentally friendly adsorbent based on PDAC was a more economical and efficient way to remove Pb(II) ions from an aqueous solution.
