Abstract

Water quality has deteriorated globally and provision of clean water is one of the most important global concerns. Currently, several toxic organic and inorganic compounds have been found at critical levels in waste, ground and surface waters. Consequently, there is an imperative demand to develop robust and environmentally friendly methods to remove them from wastewater. In this regard, numerous physic-chemical treatment technologies have been reported to control/minimize water pollution. Adsorptive removal of toxic compounds using advanced porous materials is one of the most appealing approaches in wastewater treatment nowadays. In recent years, the metal-organic frameworks (MOFs), a subgroup of advanced porous nano-structured materials, due to their exceptional characteristics, are showing great potential for improved adsorption/separation of various water contaminants. In this work, we report a family of new zinc and copper MOFs based on diazo and oxim ligands that were synthesized solvothermally under conventional electric heating, using reported methods. In order to assess the effectiveness of synthetized MOFs in adsorption-related purposes, the materials were characterized with various techniques such as nitrogen adsorption and scanning electron microscopy (SEM). The adsorptive removal of hazardous materials from water is related to high surface area derived from their huge porosity; that make MOFs superior to other porous adsorbents for efficient adsorptive removal of hazardous compounds present in wastewater.
