Abstract: The paper aims to study the remediation techniques of antimony (Sb), and summarize the concerning research in recent 10 years. The paper introduces the chemical forms and contamination sources of Sb which are relevant aspects to understand and develop remediation techniques. The most common removal techniques of Sb (adsorption, coagulation/flocculation and electrochemical methods) are presented with discussion on their advantages and drawbacks. Literature review on adsorption focuses on detail. Recent researches have focused especially on available low- cost adsorbents, such as carbon materials, biosorbents, minerals and metallic oxides. Maximum adsorption capacities and other details are accurately compiled for Sb (III, V) species. Some aspects related to economic aspects and adsorption mechanisms are also discussed. The present removal techniques can hardly meet the demands, and some researches in adsorption of Sb should be strengthened in the future. Therefore, the development and preparation of new efficient adsorbents is very important.
