ZINC ADSORPTION IN BENTONITE CLAY: PARTICLE SIZE AND pH INFLUENCE

open access: yesRevista Caatinga, 2008
In environmental studies is important to know the adsorption process of heavy metals in clay minerals, since they are able to immobilize these metals. Knowing the cations adsorption is influenced for several factors, the objective of this research was to

Nano-structured natural bentonite clay coated by polyvinyl alcohol polymer for gamma rays attenuation

open access: yesJournal of Theoretical and Applied Physics, 2019
The main goal of this work is to find natural rock materials that can be used as effective gamma rays shielding at minimal cost, reliability and wide applications. It must be at particular weight and volume (lighter and more protection).

Low fouling conditions in dead-end filtration: Evidence for a critical filtered volume and interpretation using critical osmotic pressure [PDF]

open access: yes, 2005
This paper presents experiments showing the existence of a critical filtered volume (CFV) when operating colloid dead-end filtration. The CFV is here defined as the filtered volume below which there is no irreversible (with respect to a break in the ...

Rheological properties of palygorskite–bentonite and sepiolite–bentonite mixed clay suspensions

open access: yesApplied Clay Science, 2014
Abstract This study examines the influence of layer charge and smectite content on the rheological properties of mixed bentonite–palygorskite suspensions. Eight bentonite samples containing smectite with layer charge ranging between 0.38 and 0.54 e/huc were used to prepare 5% w/v mixed palygorskite–bentonite aqueous suspension at pH 7.
