Structural characterisation of Arquad® 2HT-75 organobentonites: surface charge characteristics and environmental application.
Explore this paper's citation graph
Summary
The investigation revealed that the arrangement and conformation of surfactant molecules in the bentonite became more regular, ordered and solid-like as of Arquad(®) 2HT-75 loading increased, which led to the formation of a positive zeta potential on the surface of organobentonites prepared with 3.57:1 and 4.75:1 Surfactant-clay (w/w) ratio.
