Abstract

The toxicity of heavy metals in the aquatic environment is a serious challenge to the global community. Even at low concentrations, heavy metals have a cumulatively destructive effect on living organisms in the aquatic environment. Biomass wastes have been investigated for heavy metals removal in the published literature; however, the low performance and capacity of the biomass represents a drawback towards effective application. Therefore, in this study, biomass waste such as corn leaves that have low cost is investigated as a precursor for eco-friendly sustainable nanostructured composite. In this research, several experiments have been conducted focusing on upgrading the capacity of the bioresource for removing heavy metals from the aquatic environment. In addition to low-cost biomass material, nanomaterials such as zinc oxide represents an attractive combination for effective removing heavy metals such as iron and nickel ions. Characterization of the synthesized composite material was conducted using XRD–FESEM-mapping and EDX–HRTEM and SAED–Zeta size and Zeta potential. Moreover, studying the efficiency of synthesized nano-composite for heavy metals ions adsorption of iron and nickel ions shows an outstanding increase of performance. The results suggest that adding nanomaterial to biomass matter and obtaining a composite at nanosize, enables the increase of the adsorption efficiency of heavy metals.

Summary

Introduction

Biomass wastes represent attractive low-cost materials for solving major environmental problems such as heavy metals in the aquatic environment. With the growth of serious problems for the environment due to the rising concentration of toxic contaminants, there is an imperative need for developing healthy, low cost and eco-friendly materials to detox and purify water sources and to protect the environment. The newly emerging field of nanotechnology offers a potential offer for water purification with low cost, high work efficiency in removing contaminants and the ability to be reused again. Several treatment techniques are available with varying degrees of success to control water contamination (Zhaojin et al 2021; Yaowei et al 2021). Many low-cost adsorbents have been studied for their ability to remove several types of contaminants from wastewater (Jingjing et al 2021; Aya et al 2021). Corn leaves, ZnO and synthesized nanocomposite will be examined for removing iron and nickel ions from the water environment
