Today freshwater is more important than ever before and it is contaminated from textile industry. Removal of dyes from effluent of textile using amorphous alloys has been studied extensively by many researchers. In this review article it is presented up to date development on the azo dye degradation performance of amorphous alloys, a new class of catalytic materials. Numerous amorphous alloys have been developed for increasing higher degradation efficiency in comparison to conventional ones for the removal of azo dyes in wastewater. One of the objectives of this review article is to organize the scattered available information on various aspects on a wide range of potentially effective in the removal of dyes by using amorphous alloys. This study comprises the affective removal factors of azo dye such as solution pH, initial dye concentration, and adsorbent dosage. It was concluded that Fe, Mg, Co, Al and Mn-based amorphous alloys with wide availability have appreciable for removing several types of azo dyes from wastewater. Concerning amorphous alloys for future research, some suggestions are proposed and conclusions have been drawn.
