Lead and copper metal ion uptake by a novel nanoscale hydroxy-terminated dendritic macromolecules

Abstract

A rapidly growing global population has prompted a pressing concern about how to maintain a safe environment for future generations as a result of massive growth in agricultural, industrial, and economic activities. Environment harmful metals are found in industrial wastewater, which can harm living organisms. Because of heavy metals' strong recalcitrance and long-term existence in the environment, it's crucial to create novel materials for their adsorption. A dendrimer is a good way to adsorb heavy metals. The current work's purpose is to design dendritic macromolecules up to generation three using 1,3-bis(4,6-Dichloro-1,3,5-triazine-2-yl)thiourea as a structural core. Dendrimer structure was characterized by FT-IR and 1H NMR measurements. The adsorption properties of synthesized dendrimer were investigated using different pH, contact duration and generation number for the removal of Pb+2 and Cu+2 metal ions from aqueous systems. Dendrimer-metal complexes were analysed using FT-IR methods to confirm their metal content. In this Research study, divergent growth of dendrimers was successfully used to synthesize different generations of hydrophilic triazine-based dendritic macromolecules. We aimed to investigate the capability of synthesized dendrimer as an adsorbent to remove Pb+2 and Cu+2 metal ion in aqueous systems. According to the study data, products synthesized with higher generations of dendrimers have greater adsorption capability than products synthesized with lower generations of dendrimers.
