Volume 4, Issue 1 , January 2019, Pages 40-47

https://doi.org/10.22090/jwent.2019.01.004

Abstract
  The remaining dye in the wastewater is not desirable as it damages the ecosystem and nature, and also is very toxic. The Crystal Violet (CV) dye is toxic and potentially carcinogenic. In addition, it reduces light in water and prevents the process of photosynthesis of aquatic plants. Therefore, nanozeolite-X ...  Read More
