Title : Zirconium phosphate-based functionalized porous inorganic-organic hybrid material for efficient removal of anionic dye
Contamination of water sources with various organic and inorganic non-biodegradable pollutants like organic dyes accelerates the risk of environmental security and human health because of industrialization, urbanization, and the shortcoming of customary wastewater treatment processes. To address past contamination and prevent further emission of these pollutants into the water supply, fresh strategies are continually being devised. Multi- functional adsorption method is the most effective method because of its high efficiency, low cost, recyclability, environmental friendliness and free from byproducts, which have attracted researchers' attention for the efficient removal of pollutants. Due to the advantages of both organic and inorganic materials, research has been focused on functionalized organic- inorganic hybrid materials. On the same note, herein we report Zirconium phosphate-based functionalized inorganic material (ZP-F) using hydrothermal and reflux methods. The roughly hexagonal flake-like 2D layered inorganic material was exfoliated to expose their acidic sites and then functionalized with organic moieties which shows the slightly restacking of nanolayers. As-synthesised Zirconium phosphate-based functionalized material shows good adsorption behaviour for anionic dye i.e. Congo Red even with a low surface area of 46.20 m2.g-1. Our material adsorbs large amount of CR dye with adsorption capacity of 1213 mg.g-1. The adsorption process is spontaneous and exothermic in nature which shows pseudo- second-order reaction with multilayer adsorption.
Audience take away:
- From this presentation, audience will learn organic modification of nanolayered inorganic material.
- Hybrid organic-inorganic material shows good adsorption apacity comparatively.
- New and growing field in material chemistry to explore more appliactions.
- Provides practical solution for wastewater treatment.
