摘　　要：证实活化煤和石油焦对水中氰化物的等温吸附规律符合Langmuir方程 .活化煤的饱和吸附量Γ∞ ≈ 547mg·g-1,吸附系数K≈ 1 0 4 7× 10 -3 dm-3·mg-1;石油焦 ,Γ∞ ≈ 561mg·g-1,K≈ 9 0 17× 10 -4 dm3·mg-1.In this paper it is proved that regularities of isothermal absorption of activated coal and petrcleum coke for cyanide in water agrees with Langmuir equation. For activated coal, quantity of staturated absorption Γ ∞≈547?mg·g -1 , absorption coefficient K=1 047×10 -3 ?dm 3·mg -1 ; for petroleum coke Γ ∞≈561?mg·g -1 ,K=9 017×10 -4 ?dm 3·mg -1 . The experimental results have theoretical and practical value in disposing cyanide in water.
