Polymerization of 3-cyanopropyl (triethoxy) silane: A kinetic study using gas chromatography
(
John Wiley and SonsInc.
, 2018 , Article)
Gas chromatography (GC) was used to study the kinetics of the 3-cyanopropyl triethoxysilane (CTES) polymerization. The reaction is a consecutive complex reaction that depends mainly on the kinetics of the first hydrolyzed ...
Recycling of Date Pits Into a Green Adsorbent for Removal of Heavy Metals: A Fractional Factorial Design-Based Approach
(
Frontiers Media S.A.
, 2019 , Article)
Date pits (DPs) have been recycled into a low-cost adsorbent for removing of selected heavy metals (HMs) from artificially contaminated aqueous solutions. Adsorption of targeted HMs, both by raw date pits (RDP) and burnt ...
Kinetics of alkoxysilanes and organoalkoxysilanes polymerization: A review
(
MDPI AG
, 2019 , Article Review)
Scientists from various different fields use organo-trialkoxysilanes and tetraalkoxysilanes in a number of applications. The silica-based materials are sometimes synthesized without a good understanding of the underlying ...
Eco-structured biosorptive removal of basic fuchsin using pistachio nutshells: A definitive screening design-based approach
(
MDPI AG
, 2019 , Article)
Biosorptive removal of basic fuchsin (BF) from wastewater samples was achieved using the recycled agro-wastes of pistachio nut shells (PNS). Seven adsorbents were developed; raw shells (RPNS) and the thermally activated ...
Bio-Waste Aloe vera Leaves as an efficient adsorbent for Titan Yellow from Wastewater: Structuring of a novel adsorbent using Plackett-Burman factorial design
(
MDPI AG
, 2019 , Article)
Titan yellow (TY), a triazene azo dye, was removed from contaminated wastewater samples using a green adsorbent recycled from Aloe vera leaves (AV) waste. Two adsorbents were developed-air-dried Aloe vera (ADAV) and thermally ...
Kinetics of alkoxysilanes hydrolysis: An empirical approach
(
Nature Research
, 2019 , Article)
Alkoxysilanes and organoalkoxysilanes are primary materials in several industries, e.g. coating, anti-corrosion treatment, fabrication of stationary phase for chromatography, and coupling agents. The hydrolytic polycondensation ...
Pomegranate peels as versatile adsorbents for water purification: Application of box–behnken design as a methodological optimization approach
(
John Wiley and Sons Inc.
, 2019 , Article)
Pomegranate peels (PGP) were tested as a green adsorbent for the removal of Ni(II) from contaminated water samples. Both raw (RPG), and char/burnt peels (BPG) were tested. A multivariate analysis approach, Box–Behnken (BB) ...
Application of fractional factorial design for green synthesis of cyano-modified silica nanoparticles: Chemometrics and multifarious response optimization
(
Elsevier B.V.
, 2018 , Article)
Cyano-functionalized spherical silica nanoparticles (SNPs) were synthesized via St?ber method. A 2 k-p IV fractional factorial design (2k-p IV-FFD) was used to smartly prepare monodispersed evenly distributed SNPs. Six ...
Activation of kaolin with minimum solvent consumption by microwave heating
(
Mineralogical Society
, 2014 , Article)
A kaolin clay was activated with 1.0 M H2SO4 solution at minimum liquid to solid ratio (L/S) using microwave heating. The optimum experimental conditions for activation were L/S ratio 3.0 mL 1 M H2SO4 per gram kaolin, ...
Magnetic solid phase extraction (MSPE) for chromatographic separation of carbamates.
(
Wiley
, 2018 , Article)
Magnetic solid phase extraction particles (MSPE) were produced using magnetite nanoparticles with diameters between 9 and 13 nm as nucleating agent. The produced particles with magnetite cores were smaller, and more irregular ...
