Effect of pH on the surface charges of permanently/variably charged soils and clay minerals [PDF]

open access: yesScientific Reports
Traditionally, the surface charge number (SCN) of permanently charged soils/clay minerals is believed to be unaffected by environmental pH. However, recent studies have revealed the occurrence of polarization-induced covalent bonding between H+ and the ...

Effect of Clay Minerals on Carbonate Precipitation Induced by Cyanobacterium Synechococcus sp. [PDF]

open access: yesMicrobiology Spectrum, 2023
Carbonate precipitation induced by cyanobacteria is an important factor in lacustrine fine-grained carbonate rock genesis. As key components of these rocks, clay minerals play an important role in aggregating cyanobacteria.

Enhanced adsorptive removal of cationic and anionic dyes from aqueous solutions by olive stone activated carbon

open access: yesComptes Rendus. Chimie, 2021
In this work, four activated carbons were synthetized from natural olive stone (NOS) wastes using ZnCl2 as an activating agent. These activated carbons (OSAC) were synthetized for a constant mass ratio of ZnCl2: NOS of 2:1, a contact time of 2 h and four

Mineral Acquisition from Clay by Budongo Forest Chimpanzees. [PDF]

open access: yesPLoS ONE, 2015
Chimpanzees of the Sonso community, Budongo Forest, Uganda were observed eating clay and drinking clay-water from waterholes. We show that clay, clay-rich water, and clay obtained with leaf sponges, provide a range of minerals in different concentrations.
