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.实验结果对水中氰化物的处理很有理论意义和实用价值
It was confirmed that the isothermal adsorption of activated carbon and petroleum coke on the cyanide in water accorded with Langmuir equation.The saturated adsorption capacity of activated coal Γ∞ ≈ 547mg · g-1, adsorption coefficient K ≈ 1047 × 10-3 dm-3 · mg -1, petroleum coke Γ∞ ≈ 561mg · g-1, K≈9 0 17 × 10-4 dm3 · mg-1. Experimental results The treatment of cyanide in water is of great theoretical and practical value
