The influence of organic modification on the structural and adsorptive properties of bentonite clay and its application for the removal of lead

Abstract

Organic modification of mineral clay using the monomer ethenyl acetate was performed. The exchange of inorganic interlayer clay cations was achieved using the cationic surfactant Genamine CTAC and Asepsol. Aiming to investigate the influence of organic modifications on adsorptive clay properties, dried composites of clay/ethenyl acetate, with different percentages of clay were soaked in distilled water. The influence of the temperature on the adsorptive properties of organoclays was also followed. The adsorptive properties of the obtained composites of organoclays with Luviskol, Carbopole and purine were investigated along with their capability for removing Pb2+ from water in charged systems.

Modified Electro-spun Polyvinyl Alcohol Nanofibers Used as Super Adsorbing Material for Lead Ions in Aqueous Solution

“…Pb 2+ ions in aqueous solution are non-biodegradable and are known to accumulate in human beings, causing many sickness and imparted health [4][5][6]. Its toxic effects are subtle with a possibility of causing permanent health problems [7].…”

An urban planning approach to the climatization of space using natural resources based on ceramic clay, zeolite and bentonite clay

“…Bentonite clay as one of them is very important for manufacturing of building materials [3]. The physicochemical properties of bentonite clay are commonly modified by addition of polymers in order to improve its characteristics [4,5]. Over the last few decades, natural construction materials have lost their leading role in the market and have been replaced by synthetic materials (e.g.…”
