New ceramic titania: Selective adsorbent for organic phosphates.

Sample Prep using Titania and Zirconia

The adsorption properties of new ceramics titania (titanium dioxide, Ti02) as a column packing material for high performance liquid chromatography (HPLC) were investigated in our recent studies. The adsorption mechanism of titania was found to be different from that of silica gel; the titania adsorbs acidic compounds rather than basic compounds, while silica gel adsorbs basic compounds. In addi...

Polyethyleneimine Incorporated Metal-Organic Frameworks Adsorbent for Highly Selective CO2 Capture

A series of polyethyleneimine (PEI) incorporated MIL-101 adsorbents with different PEI loadings were reported for the first time in the present work. Although the surface area and pore volume of MIL-101 decreased significantly after loading PEI, all the resulting composites exhibited dramatically enhanced CO2 adsorption capacity at low pressures. At 100 wt% PEI loading, the CO2 adsorption capac...

Organic-inorganic hybrid nanomaterial as a new fluorescent chemosensor and adsorbent for copper ion.

Functionalized silica nanotube (FSNT) possessing the phenanthroline moiety as a fluorescent receptor was fabricated by solgel reaction, and the binding ability of FSNT with metal ions was evaluated by fluorophotometry.

Photocatalytic Application of Titania Nanoparticles for Degradation of Organic Pollutants

A robotics-based automated assay for inorganic and organic phosphates.

Phosphate analyses are fundamental to a broad range of biochemical applications involving inorganic phosphate and organic phosphoesters such as phospholipids, phosphorylated proteins, and nucleic acids. A practical automated method utilizing robotics is described in this report. Five colorimetric methods of phosphate analyses based on formation of a phosphomolybdate complex and compatible with ...
