Study: The Removal of Heavy Metals August 13th, 2009
Many toxic heavy metals have been discharged into the environment as industrial wastes, causing serious soil and water pollution.
In this study, the adsorption behavior of natural (clinoptilolite) zeolites with respect to Co2+, Cu2+, Zn2+, and Mn2+ has been studied in order to consider its application to purity metal finishing wastewaters.
Conclusion: These results show that natural zeolites hold great potential to remove cationic heavy metal species from industrial wastewater. This naturally occurring material provides a substitute for the use of activated carbon as adsorbent due to its availability and its low cost.
