Reduction of Cadmium Availability to Tobacco ( Nicotiana tabacum ) Plants using Soil Amendments in Low Cadmium-contaminated Agricultural Soils: A Pot Experiment [PDF]

, 2018
Cadmium (Cd) concentration in field-grown tobacco leaves usually ranges from < 0.5 to 5mgCdkg-1 dry matter (DM). Reducing bioavailability of soil Cd by adding amendments to the soil could be suitable to mitigate Cd uptake by tobacco plants.

Potential for using sepiolite as dispersing agent in phenolic resin crosslinked natural rubber/silica composites

eXPRESS Polymer Letters
Natural rubber (NR) composites filled with silica and crosslinked with phenolic resin were prepared in this study. The influence of a small sepiolite addition (1–5 part(s) per hundred parts of rubber, phr) on the properties of NR composites was studied ...

Garnierite Mineralization from Falcondo Ni-Laterite Deposit (Dominican Republic) [PDF]

, 2017
Mine geologists use the term "garnierite" for the green Ni-rich silicate minerals that occur in many Ni-laterite deposits. However, garnierite is not a mineral species recognized by the Commission on New Mineral and Mineral Names (CNMMN).

Effect of acid treatment on the structure of sepiolite. [PDF]

, 2003
An ab initio determination of the structure of sepiolite after acid treatment (HCl 0.5 N for 24 h) was carried out using X-ray powder diffraction data. After acid treatment, the sections normal to the a and c axes presented discontinuities, ~2.25 Å wide,

Adsorption of lead and nickel from aqueous solution on natural sepiolite [PDF]

, 2017
Heavy metals are a serious environmental problem due to their toxicity and abundance. The capacity of a natural clay (sepiolite) for heavy metals adsorption, Pb2+ and Ni2+, has been assessed using a batch method.
