Abstract
We collected systematically the bibliographic data bases for peer-reviewed research literature focusing on the theme of our review. The quality of the included research papers are selected by standard tools. A conceptual frame work is designed to arrange the topics and extracted the interventions and findings of the included studies. The overall study was divided into sections and each section incorporated the most appropriate literature citation. Total one hundred and eight references were included of which 32 references were used for basic description/introduction of core-shell magnetic nanocomposites. One review paper containing the synthesis methods for core shell magnetic nanocomposites is included while majority (76) of the references are included for comprehensive description of applications of the core-shell nanocomposites among which 25 were for dyes removal, 27 for hazardous metals, 07 for hazardous chemicals, 12 for pesticides and biological contaminants removal and five other including patents were added as miscellaneous substances removal from water sources. This review identified the effective role of core-shell magnetic nanocomposites for environmental remediation in terms of removal of various hazardous substances from water resources. The outcome of the present review confirms that the magnetic core-shell nanocomposites provide a cost effective and efficient way for the removal of various toxic substances including dyes, heavy metals, toxic organic chemicals, pesticides and some biological contaminants from water sources.
