Abstract:Thiocyanate-bearing wastewater comes from many industrial processes, such as hydrometallurgy, flotation, coal coking, printing and dyeing textiles, acrylic fiber production, finishing and electroplating. Due to its anti-hydrolysis and non-volatile, it has potential toxicity to human body and aquatic organisms, and also has a certain threat to good water quality. Therefore, thiocyanate must be neutralized or removed from wastewater before being released into environment. In this paper, advantages and disadvantages of methods to remove thiocyanate from wastewater are summarized and prospected.
