Simultaneous quantification of acetaminophen and tryptophan using a composite graphene foam/Zr-MOF film modified electrode
(Royal Society of Chemistry, 2020)
A graphene foam/zirconium-based metal–organic framework composite (GF/UiO-66) was synthesised and then employed to modify glassy carbon electrodes (GCE). These modified electrodes were successfully used for the simultaneous ...
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)
Biochars have been extensively applied in soil remediation, carbon sequestration, and in climate change mitigation. However, in recent years, there has been a significant increase in biochar research in water treatment due ...
Effects of copper exchange levels on complexation of ammonia in Cu (II)-exchanged X zeolite
(Sabinet, 2010-01-01)
Copper (II)-exchanged faujasite-X zeolites at various loadings of copper per unit cell of zeolites were prepared and then exposed to ammonia. The copper ammine complexes of the various copper levels per unit cell were ...
