Simultaneous degradation and adsorption of cyanide using modified fly ASH and TiO2/UV

Due to the present water shortage and environmental problems associated with industrial effluent, investigation of novel treatment technologies is an essential approach. Being a highly toxic chemical of asphyxiating characteristics, cyanide is seen as a major environmental pollutant in a wide range of industrial effluents. The present study aimed to address the adsorption and photocatalytic deg...

Arsenic (V) removal from aqueous system using adsorbent developed from a high iron-containing fly ash.

A novel adsorbent for arsenic (V) removal from wastewater was developed through simple chemical processes using a special iron-abundant fly ash. In the synthesis process, the inherent iron in the fly ash was rearranged and loaded on the surface of the fly ash by dissolution and precipitation processes. The adsorbent (HIOFAA) was characterized by XRD, FT-IR, SEM, LPS and BET surface area. The re...

Heavy Metals Removal on Dye – Modified Fly Ash Substrates

The fly ash is a cheap waste materials which can be an efficient substrate in wastewater treatment for the immobilization of heavy metals, mainly Cd, Pb, Ni, Zn, Cu, and for dyes removal. The use of FA for heavy metals removal, from wastewaters resulted in the dye finishing industry, faces a supplementary problem, related to the dyes affinity for oxide surfaces. Working with industrial wastewat...

Photocatalytic removal of o-chlorophenol by Using a Mixture of Modified Fly Ash and TiO2 Nanoparticles

Abstract Background: Photocatalytic process is used as a suitable method for o-chlorophenol removal. In this study, the efficiency of a mixture of modified fly ash and TiO2 nanoparticles in photocatalytic removal of o-chlorophenol was evaluated. Methods: After acid washing of fly ash, the absorbent was oxidized with potassium permanganate. ...

Removal of Cr(VI) from Wastewater using Fly ash as an Adsorbent

Cr(VI) is a highly toxic metal ion and considered a priority pollutant released from various chemical industries. Treatment methods to remove Cr(VI) from water and wastewater include chemical precipitation, ion exchange, membrane separation, electro-coagulation and reduction. These methods are not economically viable for large scale treatment of wastewater that is rich in Cr(VI). Adsorption is ...
