Project Description and Objectives
In recent decades, antimony (Sb) contamination in printing and dyeing wastewater has attracted people's attention. Conventional techniques to remove Sb from water include reverse osmosis, electrodeposition, precipitation/coagulation, membrane filtration and adsorption. Adsorption is one of the best available treatment technologies, because it is simple, safe, compact, easy to operate and highly efficient. The traditional adsorbents, such as biomass carbon, zeolite, metal mineral adsorbent, have the disadvantages of low adsorption capacity and small adsorption rate. Therefore, we developed a new organic adsorbent-the modified PAN with amidoxime group to remove antimony ions from wastewater. In batch experiment, the modified PAN had a good adsorption, which is a promising candidate for the removal of Sb from water.
Synthesis, characterization and performance test of new adsorbent.
