Abstract
Today’s necessity is to achieve a sustainable environment. But, over the past three decades, various research articles reported the presence of new compounds in aquatic environment as well as in wastewater effluents, called ‘Emerging Pollutants’. Although such materials are widespread in water effluents, their toxicity and impacts on both human health and the ecosystems are poorly understood since there are no regulatory data for those contaminants. However, ever increasing of the socio-economic awareness and scientific information, scientists have become more concern for the Emerging Pollutants (EPs), widespread and their distribution in the environment. Their successful control represents the primary challenge to the industrial sector and academia. Therefore, developing technological advancement in eco-friendly environmental wastewater treatment strategies is a must. This drive the multi-disciplinary blend of chemical science, environmental engineering and industry to realise this concern from both an operational and public health standpoint. The boom of Fenton or Fenton-type modified reactions offers potential opportunities for innovative remediation techniques. The aim of this review is to update and contribute the recent developments to overcome the Fenton reaction obstacles such as acidic environment, ferric sludge production and reagent’s cost that limits its application for better frameworks. In particular, recent Fenton’s reaction approaches on the EPs removals deserve further research to adopt the system and could give rise to real applications.
