Effect of pyrolysis temperature on ochratoxin A adsorption mechanisms and kinetics by cashew nut shell biochars [PDF]

open access: yes, 2019
Biochars were produced from cashew nut shell at 400, 600 and 800°C. Production temperature significantly affected biochar properties and consequently the adsorption mechanisms of ochratoxin A.

Preparation of Graphene via Thermal Reduction and Its Adsorption Capacity for Heavy Metal Pb2+

open access: yesCailiao gongcheng, 2017
Graphene(GR) was obtained by reduced graphite oxide(GO) by instantaneous heating. Thermal reduced graphene was used to adsorb heavy metal Pb2+ ions in water to study the effect of adsorption time and pH value on the adsorption.

The dependence of the hydrogen sorption capacity of single-walled carbon nanotubes on the concentration of catalyst [PDF]

open access: yes, 2009
The adsorption of hydrogen on single-walled carbon nanotubes was measured using micro-gravimetric nitrogen and hydrogen adsorption isotherms at 77 K for gas pressures of up to 1 bar (nitrogen) and 12 bar (hydrogen).

Determination of biosorption mechanism in biomass of agave, using spectroscopic and microscopic techniques for the purification of contaminated water [PDF]

open access: yes, 2019
[Abstract] Lead (Pb2+) and copper (Cu2+) are polluting metals due to their toxicity; however, the extraction of these metals is essential for economic development, so it is important to look for efficient and low-cost alternatives that can remove heavy ...
