| Abstract: |
| The current situation in the research of application tourmaline to environmental engineering was introduced.With the black tourmaline from Chifeng in Inner Mongolia as absorbent,the paper systematically researched the effect of adsorption time,temperature,consumption,pH value,initial density of metal ion on adsorption of Cu~(2+),Pb~(2+),Zn~(2+).Following that the paper described the adsorption characteristics of the absorbent through using Langmuir and Freundlich adsorption equal temperature line,and discussed the adsorption law of tourmaline on the heavy metal ions in real waste water.And finally,the paper studied the infrared emission characteristic of the tourmaline. |
