Jan 25, 2024 · Thallium, a highly toxic trace element, being released into the environment by industrial mining has caused serious environmental pollution. Here, a magnetic Prussian Blue (PB) nanosorbent loading on sepiolite (PB/Fe 3 O 4 /SEP) was successfully synthesized for the deep treatment of Tl(I) based on its high adsorption capacity. The high adsorption capacity of …

Apr 20, 2018 · In this work, industrial grade sepiolite (IG-SEP) was premodified with hydrochloric acid, and then premodified sepiolite (SEP) was impregnated with triethylenetetramine (TETA) to create a novel TETA functionalized SEP adsorbent. The effects of TETA loading and adsorption temperature on CO2 adsorption capacity, as well as the CO2 adsorption isotherm and cyclic …

Mar 15, 2020 · Sepiolite has potential to decrease Cd contents in spinach, particularly at higher rate. The increment in soil pH is considered the key factor to minimize soil heavy metal availability (Lindsay, 1979). Natural sepiolite contains sufficient amount of CaCO 3 and (CaMg (CO 3) 2) which has potential to increase soil pH (Liang et al., 2016; Sun et ...

Oct 1, 2012 · Sepiolite is a mineral with fibrous morphology due to its crystalline structure. The structure of this mineral was described by Brauner and Presinger (1956) as continuous sheets of tetrahedral silica that have an apical oxygen periodically inverted. This periodical inversion produces each three tetrahedral chains in the [001] direction.

Nov 1, 2024 · Sepiolite is a natural clay mineral with a 1D fiber-like structure, which has the advantage of being inexpensive, hydrophilic and highly adjustable concentration in aqueous dispersions [33]. Sepiolite fibers can serve as embedding layers, meantime further enhancing the performance of TEPG due to its abundant active sites [34]. However, there is ...

Jan 9, 2024 · Cadmium (Cd) pollution in agricultural soils has become a priority environmental concern globally. A reasonable application of passivators is critical to address the problem. In this study, we examined the remediation effects of rice husk biochar (rBC) and sepiolite (Sep) as single and combined (rBC + Sep) treatments on Cd pollution in a weakly alkaline soil …
