Abstract: 

This paper presents the results of studies on the ability to handle cyanide in metal plating wastewater in the Thanh Thuy village of Thanh Oai district, Hanoi city. The results showed that water hyacinth plants are capable of well growing in the water of pH from 6.00 to 7.00. This plant can be applied for treat cyanide in metal plating wastewater with the concentration about 0.190 mg/L. The water hyacinth with the 2days of age can be applied in treating cyanide with the highest efficiency, reached 89.4 %.
