Carbon nanotube impregnated anthracite (An/CNT) as a superior sorbent for azo dye removal

Abstract

<p>Raw anthracite was impregnated with a minute amount of multi-walled carbon-nanotubes at a solid/solid ratio of 50 : 1 <italic>via</italic> calcination at 950 °C for 2 h to produce anthracite/carbon nanotube (An/CNT) composite with superior sorption efficiency.</p>

A New Method of Diatomaceous Earth Fractionation—A Bio-Raw Material Source for Epoxy-Based Composites

“…As mentioned above, diatomaceous earth contains diatom frustules of various sizes, a lot of fractions that are mechanically damaged, as well as agglomerates and colonies. In the literature, there are methods for purifying diatomaceous earth with the use of thermal and thermo-chemical treatments [ 14 ]. Sun et al [ 15 ] cleaned diatomaceous earth using sodium hexametaphosphate as a dispersant combined with centrifugation.…”

From Hazardous Chrysotile and Polyamide Wastes into Sustainable Serpentine/Polyamide Nanocomposite Membrane: Fabrication, Characterization, and Environmental Application

“…The R% of MO and MB by the SP/PAM was improved from 19.88 to 41.95% and from 10.17 to 17.94% with enhancing the dose from 10 to 35 mg, correspondingly. This realistic improvement in the removal capacity of the investigated dyes was correlated to the increase in the available binding sites on the composite surface [6,63]. Similarly, the impact of SP/PAM dose (20 to 70 mg) on the R% of Fe(III) from standard solution with fixed initial concentration (3 mg/L), keeping the other experimental parameters constant (Table 1), is depicted in Figure 9b.…”

Synthesis of flower-like MoS2/CNTs nanocomposite as an efficient catalyst for the sonocatalytic degradation of hydroxychloroquine

“…The resultant pattern for the CNTs revealed a broad but intense peak at the 2θ of 26.1°, which can be attributed to the reflection of the (0 0 2) plane in its graphitic crystalline structure. Moreover, the peaks observed in the 2θ range of 42–46° can be assigned to the reflection of the (1 0 0) and (1 0 1) planes within the graphenic layers of CNTs [22] , [23] . The diffraction peaks centered at 2θ = 14.2°, 33.7°, 39.6°, 49.5°, and 58.9° correspond to the reflection of the (0 0 2), (1 0 0), (1 0 3), (1 0 5), and (1 1 0) planes in the hexagonal structure of MoS 2 (JCPDS card No.…”
