Journal ArticleDOI
Efficient Removal of Pb(II) from Aqueous Solutions by Using Oil Palm Bio-Waste/MWCNTs Reinforced PVA Hydrogel Composites: Kinetic, Isotherm and Thermodynamic Modeling.
Muhammad Zulfiqar,San Yi Lee,Amira Azreena Mafize,Nur Adlin Mastura Abdul Kahar,Khairiraihanna Johari,Nurul Ekmi Rabat +5 more
TL;DR: It was found that reinforced nanocomposites exhibited enhanced mechanical properties as compared to non-reinforced material and the coordination effects among OPB, MWCNTs and PVA polymer hydrogels can produce a promising adsorbent material for wastewater treatment applications.
Journal ArticleDOI
Development of coconut pith chars towards high elemental mercury adsorption performance - Effect of pyrolysis temperatures.
TL;DR: The Hg(o) adsorption capacity of chars obtained from high pyrolysis temperature of CP significantly outperformed the commercial activated carbon (Darco KB-B) as well as superior to chars reported in the literature indicating the CP can be used as a precursor for preparation of chars as elemental mercury adsorbents.
Journal ArticleDOI
Improved interfacial bonding of graphene-TiO2 with enhanced photocatalytic reduction of CO2 into solar fuel
Nasir Shehzad,Nasir Shehzad,Muhammad Tahir,Khairiraihanna Johari,Thanabalan Murugesan,Murid Hussain +5 more
TL;DR: In this paper, a facile two-step approach was employed to synthesize the reduced graphene oxide (rGO) and titanium dioxide (TiO2) photocatalyst, which involved partial reduction of graphene oxide followed by vacuum thermal treatment.
Journal ArticleDOI
Adsorption Characteristics of Sulfur-Functionalized Silica Microspheres with Respect to the Removal of Hg(II) from Aqueous Solutions
TL;DR: In this article, the adsorption characteristics of sulfur-functionalized silica microspheres (S-SMs), synthesized through co-condensation of tetraethyl orthosilicate with 3-mercaptopropyl trimethoxysilane (MPTMS) and bis(triethoxyilylpropyl) tetrasulfide (BTESPT) as sulfur ligands, with respect to the removal of Hg(II) from aqueous solutions were studied.
Journal ArticleDOI
Utilization of Coconut Milk Processing Waste as a Low-Cost Mercury Sorbent
TL;DR: In this article, the authors used the Fourier transform infrared (FTI) measurements to confirm the existence of hydroxyl, carboxyl, and amine groups on the DCWS surface, and fitted the batch equilibrium data with a maximum sorption capacity, qmax of 500 mg/g, while the kinetic sorption data were found to follow a pseudo-second-order kinetic model.
