Abstract
The discharge of untreated wastewater become a major threat to the environment and posed health risk to human. Thus, in this study a low-cost and eco-friendly bio-sorbent produced from cheap and lo...
Highlights
Environmental pollution due to heavy metal is severe and complex that has been received attention due to its toxicological effects on the environment and human health, even at very low concentrations
The objective of this study was to investigate the bio-sorbent prepared from E. camaldulensis as an alternative choice of commercial activated carbon in the removal of Pb, Cd and Cr from aqueous solution and industrial wastewater in batch mode studies; study the influence of various parameters such as pH, initial concentration of metal ion, contact time and adsorbent dose on the removal efficiency of the bio-sorbent and determine the best-fit isotherm equation, the experimental equilibrium adsorption data using Langmuir and Freundlich isotherm models
This study was carried out to evaluate the efficiency of E. camaldulensis activated carbon (ECAC) on the removal of metal ions from synthetic solution and industrial effluents
Summary
Environmental pollution due to heavy metal is severe and complex that has been received attention due to its toxicological effects on the environment and human health, even at very low concentrations. High levels of heavy metals were obtained in untreated industrial wastewater which pollutes the ground and surface water once it is discharged to the environment. Among these toxic metals; arsenic (As), chromium (Cr), copper (Cu), zinc (Zn), aluminum (Al), cadmium (Cd), lead (Pb), nickel (Ni), mercury(Hg), and silver (Ag) are the major ones (El Nemr, Khaled, Abdelwahab, & El-Sikaily, 2008). The removal of toxic heavy metals from industrial wastewater is primary importance in terms of the protection of public health and environment
