Diacetylmonoxime Functionalized Silica Gel: An Efficient and Recyclable Organic Inorganic Hybrid Material for Selective Removal of Copper from Fly Ash Ameliorated Soil Samples

Functionalized Mesoporous Silicon Nanomaterials in Inorganic Soil Pollution Research: Opportunities for Soil Protection and Advanced Chemical Imaging

“…In this study through FTIR, element analysis, BET surface area analysis, and 13 C CPMAS NMR spectroscopy, it was shown that the FMSN have high selectively for Cu removal with a preconcentration factor of 250; sorption capacity reached 0.93 mmol g −1 . Kinetic parameters and isotherms correlated well with the pseudo-second-order and Langmuir models [75]. Another important study reported that FMSN can limit the absorption of toxic metals and As by plants through reducing bioavailability.…”

“…Although the use of functionalized silica in soils is relatively new, there have already been a number of successful applications. For example, diacetylmonoxime-functionalized silica gel has been used to remove Cu from fly ash-ameliorated soil samples [75]. In this study through FTIR, element analysis, BET surface area analysis, and 13 C CPMAS NMR spectroscopy, it was shown that the FMSN have high selectively for Cu removal with a preconcentration factor of 250; sorption capacity reached 0.93 mmol g −1 .…”

A highly efficient and magnetically retrievable functionalized nano-adsorbent for ultrasonication assisted rapid and selective extraction of Pd2+ ions from water samples

“…[21][22][23][24][25] In continuation of our research efforts directed towards the development of organic-inorganic hybrid materials for the efficient determination and recovery of heavy metals, we herein, report the synthesis of a magnetically driven core-shell nanoadsorbent through the covalent immobilization of 2,6-diacetylpyridine monothiosemicarbazide on amine functionalized silica coated magnetic nanoparticles. [26][27][28][29][30] The newly fabricated nano-adsorbent was then applied for the selective extraction of Pd 2+ ions from different water samples. It was found that, in comparison to the previous reports the DAPTS@NH 2 @SiO 2 @ Fe 3 O 4 nano-adsorbent not only exhibited exceptional adsorption characteristics by rapidly, efficiently and selectively adsorbing Pd 2+ ions from the bulk solution containing the complex matrix of multiple interfering ions but also showed higher reusability.…”

Advances in organic–inorganic hybrid sorbents for the extraction of organic and inorganic pollutants in different types of food and environmental samples

“…The adsorbent could be regenerated at least four times and its high stability after regeneration at room temperature was up to 6 months. Another SPE adsorbent, diacetylmonoxime functionalized silica gel (Si‐NH 2 ‐DAC) was applied in the extraction of Cu(II) from fly ash ameliorated soil . It was synthesized by functionalizing silica gel (Si) with (3‐aminopropyl)trimethoxysilane (Si‐NH 2 ) followed by the covalent immobilization with diacetylmonoxime.…”
