Polymer-based TiO2 nanocomposite membrane: synthesis and organic pollutant removal

Sonocatalytic removal of an organic dye using TiO2/Montmorillonite nanocomposite.

The sonocatalytic performance of the synthesized TiO2/Montmorillonite K10 (TiO2/MMT) nanocomposite was studied in removal of Basic Blue 3 (BB3) from water. The TiO2/MMT nanocomposite was prepared by hydrothermal method. Scanning electron microscope, X-ray diffraction and Fourier transform infrared were used to characterize the synthesized nanocomposite. The average size of TiO2 nanoparticles de...

Synthesis of Water-Based Dispersions of Polymer/TiO2 Hybrid Nanospheres

We develop a strategy for preparing water-based dispersions of polymer/TiO₂ nanospheres that can be used to form composite materials applicable in various fields. The formed hybrid nanospheres are monodisperse and possess a hierarchical structure. It starts with the primary TiO₂ nanoparticles of about 5 nm, which first assemble to nanoclusters of about 30 nm and then are integrated into monomer...

Screening Indoor Plants for Volatile Organic Pollutant Removal Efficiency

Twenty-eight ornamental species commonly used for interior plantscapes were screened for their ability to remove five volatile indoor pollutants: aromatic hydrocarbons (benzene and toluene), aliphatic hydrocarbon (octane), halogenated hydrocarbon [trichloroethylene (TCE)], and terpene (a-pinene). Individual plants were placed in 10.5-L gas-tight glass jars and exposed to ’10 ppm (31.9, 53.7, 37...

Feasibility of Polysulfone as Base Polymer in a Polymer Inclusion Membrane: Synthesis and Characterisation

Polysulfone was investigated as an alternative base-polymer for polymer inclusion membranes (PIM’s) that could withstand harsh environmental conditions and have good transport efficiency of metal ions. PIM’s were prepared using polysulfone as a base polymer and Aliquat 336 as a carrier in the absence of a plasticizer. Chromium (VI) was used as standard to study the extraction efficiency of the ...
