  • Effects of metal stabilizers on soil hydraulic characteristics and mobility of cadmium. [Journal Article]
    Environ Sci Pollut Res Int. 2020 Jun 12 [Online ahead of print]Liu L, Luo D, … Wu Q
  • This study investigated the effect of typical stabilizers on hydraulic properties, immobilization, and leachate characteristics based on the diffusive gradient thin-films technique (DGT) and a leaching experiment. Three types of stabilizers were classified based on various characteristics of soil field capacity (θf), and their immobilization effects were as follows: (i) θf increased and the immob…
  • The Immobilization Effect of Natural Mineral Materials on Cr(VI) Remediation in Water and Soil. [Journal Article]
    Int J Environ Res Public Health. 2020 Apr 20; 17(8)Zhang D, Xu Y, … Zou D
  • The effects of sepiolite, montmorillonite, and attapulgite on the removal and immobilization of Cr(VI) in water and soil were studied. X-ray diffraction (XRD) characterizations showed that the purities of these three mineral materials decreased in the following order: montmorillonite > attapulgite > sepiolite, and that their surface molecular bond types were similar. The adsorption potential of C…
  • Collagen, polycaprolactone and attapulgite composite scaffolds for in vivo bone repair in rabbit models. [Journal Article]
    Biomed Mater. 2020 Mar 27 [Online ahead of print]Zhao H, Zhang X, … Zhao X
  • Although numerous materials have been explored as bone scaffolds, many of them are limited by their low osteoconductivity and a high biodegradability. Therefore, new materials are desired to induce bone cell proliferation and facilitate the bone formation. Attapulgite (ATP) is a hydrated silicate that exists in nature as a fibrillar clay mineral and is well known for its large specific surface ar…
  • Fractal-Like Kinetics of Adsorption Applied to the Solid/Solution Interface. [Journal Article]
    ACS Omega. 2020 Mar 17; 5(10):5105-5115.El Bardiji N, Ziat K, … Saidi M
  • In this paper, the fractal-like multiexponential (f-mexp) equation was modified by introducing the fractional fractal exponent to each stage of the adsorption process. The new equation was used for the analysis of kinetic adsorption of copper onto treated attapulgite. The modeling results show that the modified f-mexp equation fits properly the kinetic data in comparison with the classical and fr…
  • Surface-Bound Humic Acid Increased Propranolol Sorption on Fe3O4/Attapulgite Magnetic Nanoparticles. [Journal Article]
    Nanomaterials (Basel). 2020 Jan 24; 10(2)Deng Y, Li Y
  • This study explored the feasibility of utilizing a novel sorbent humic acid (HA) coated Fe3O4/attapulgite (MATP) magnetic nanoparticles (HMATP) for the sorption of propranolol from aqueous solutions. MATP and bare Fe3O4 nanoparticles were also synthesized under similar preparation conditions. The FTIR, Zeta potential, XRD, VSM, TEM, and TGA analyses were conducted to characterize the sorbent mate…
  • Electrical-Driven Release and Migration of Herbicide Using a Gel-Based Nanocomposite. [Journal Article]
    J Agric Food Chem. 2020 Feb 12; 68(6):1536-1545.Zhang L, Chen C, … Cai D
  • In this work, an electrical-driven release and migration glyphosate (EDRMG) was fabricated using a nanocomposite made up of attapulgite (ATP), glyphosate (Gly), and calcium alginate (CA). Therein, ATP-CA acted as a nanonetwork-structured carrier to efficiently load plenty of Gly to form porous ATP-Gly-CA hydrogel spheres (actually EDRMG-0.5) via a cross-linking reaction. The pores in EDRMG-0.5 hy…
  • Cyclodextrin-based sorbents for solid phase extraction. [Journal Article]
    J Chromatogr A. 2020 Jan 04; 1609:460654.Gentili A
  • Cyclodestrins (CDs) are cyclic oligosaccharides well-known for their ability to form host-guest inclusion complexes with properly sized compounds. They have been used for decades as chiral selectors as well as drug delivery systems within the frameworks of separation science and pharmaceutical science. More recently, their use has been extended to the field of extractive science under the stimulu…
  • Robust superhydrophobic attapulgite meshes for effective separation of water-in-oil emulsions. [Journal Article]
    J Colloid Interface Sci. 2019 Dec 01; 557:84-93.Li H, Zhu G, … Li J
  • Special-wetting materials have been broadly studied in various oil/water separation processes. However, there are granted numerous challenges in extremely durable materials with mechanical robustness, especially considering the great requirements in purifying emulsified oil/water mixtures. Herein, we present a facile route to prepare robust superhydrophobic surface by spraying Octadecyltrimethoxy…
