| Abstract: | Objective]The research aimed to study the adsorption of COD by using heulandite in Wuhan South Lake.Method]Taking heulandite as adsorbent,the effects of the adsorption time of adsorption,the dosage of adsorbent,article size and the pH of solution were studied..Result]The heulandite had a good adsorption effect on COD in South Lake water.When the time of 40 minutes,the dosage of 20 g/L,the grain size less than 74 μm,the pH of 7,its adsorption rate was about 63％.The adsorption process conformed to pseudo-second order equation,the adsorption isotherms followed the Langmuir isothermal equation more exactly.Conclusion]The study provides the basis for the application of natural zeolite in wastewater. |
