Abstract
The invention relates to a method for preparing amorphous molybdenum oxide adsorption material and an application thereof. The invention aims to solve the technical problem of low recovery efficiency of silver ions in coexisting silver-containing wastewater in the prior art. The method of the present invention includes:1) preparation of electrolyte; and 2) subjecting to cyclic voltammetry. The amorphous molybdenum oxide adsorption material prepared by the present invention is used as an adsorbent for adsorbing and reducing silver ions in wastewater. The invention successfully prepares amorphous molybdenum oxide (MoOx) by cyclic voltammetry, which has a highly selective reduction adsorption for Ag+. Silver ions and the adsorbent MoOx could be subjected to redox reaction to remove silver ions in water. The removal efficiency of the silver ions in wastewater by the amorphous molybdenum oxide prepared by cyclic voltammetry of the invention is up to 99.85%.
