The effects of metakaolinization and fused-metakaolinization on zeolites synthesized from quartz rich natural clays
(Elsevier, 2019-12-01)
A variety of zeolites have been synthesized by performing either metakaolinization or fused-metakaolinization of natural clays prior to the hydrothermal synthesis step. To understand the differences arising from performing ...
Preparation, characterization of fish scales biochar and their applications in the removal of anionic indigo carmine dye from aqueous solutions
(IWA Publishing, 2019-12-01)
The preparation and applications of Tilapia (Oreochromis niloticus) fish scale biochars (FSB) as an adsorbent in the removal of indigo carmine dye (ICD) from aqueous solutions is described. The biochars were prepared through ...
Removal of Dyes From Wastewater by Adsorption Onto Low-Cost Adsorbents
(IGI Global, 2020)
This chapter describes an up-to-date critique of the use of adsorption as a wastewater treatment technique for the removal of dyes. The topics range from the classification of dyes, their occurrence in water and toxicity, ...
Preparation and Application of Biochars for Organic and Microbial Control in Wastewater Treatment Regimes
(IGI Global, 2019)
