Role of Powdered Activated Carbon in the Adsorption Behaviour of Hazardous Lead (Pb) using PDAC as an Adsorbent

Abstract

The purpose of the investigation was to remove the Pb from the artificial liquid using PDAC. 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. In this research, PDAC was explored for its possible consumption as an ecofriendly bio-adsorbent to remove the Pb (II) ions. In this investigation, adsorption-related variables, including initial dye concentration, contact time, absorption rate, temperature effects, and pH were studied. Second-order kinetic model being used for calculate the investigational values. Absorption equilibrium was determined using Longmuir and Friendlich's isothermal models. Current work suggests that PDAC could be employed as a low-cost absorbent to adsorb the lead ion in an artificial liquid solution. Adsorption characteristics were determined by SEM, XRD, and FTIR studies.
