Insights into the competitive adsorption of pollutants on a mesoporous alumina–silica nano-sorbent synthesized from coal fly ash and a waste aluminium foil

Abstract

A highly efficient and low-cost alumina–silica nano-sorbent was fabricated and characterized to realize the key factors responsible for its superiority over the existing adsorbents in treating the wastewater for the removal of dyes and heavy metals.

Equilibrium Isotherms and Kinetic Effects during the Adsorption of Pb(II) on Titanosilicates Compared with Natural Zeolite Clinoptilolite

“…The adsorption, separation, and ion-exchange properties of zeolites stem from their distinctive three-dimensional porous framework structure [17]. Natural zeolites such as clinoptilolite (CPT) [18,19] and chabazite (CHZ) [20] are extensively studied because of their natural abundance and low cost of procurement, making them economically suitable for large-scale application in agriculture [21][22][23], construction [24,25], as molecular sieves [26], and in the field of environmental preservation [27][28][29][30][31][32][33][34][35]. The vast majority of the studies on natural zeolites are concentrated on their application as adsorbents in water and wastewater treatment, for the removal of heavy metals and organic pollutants (e.g., dyes, ammonia, aniline, etc.)…”

Sunlight driven photocatalytic degradation of organic pollutants using a MnV2O6/BiVO4 heterojunction: mechanistic perception and degradation pathways

“…Consequently, it is significant that each individual must contribute to save and protect the environment from various pollutants. Very important assets for life like water and air are under continuous threat from various organic pollutants and toxic chemicals generated from chemical, agricultural, food and textile industries that act as poisons [1,2]. Carcinogenic dyes present in water restrict the path of sunrays and obstruct these from entering the aqueous system.…”
