Chitosan/mangiferin particles for Cr(VI) reduction and removal

Kinetics and mechanism of the reduction of CrVI and CrV by D-lactobionic acid.

The oxidation of D-lactobionic acid by Cr(VI) yields the 2-ketoaldobionic acid and Cr(3+) as final products when a 20-times or higher excess of the aldobionic acid over Cr(VI) is used. The redox reaction takes place through a complex multistep mechanism, which involves the formation of intermediate Cr(IV) and Cr(V) species. Cr(IV) reacts with lactobionic acid much faster than Cr(V) and Cr(VI) d...

Occupational Exposure to Hexavalent Chromium (CrVI)

synthesis of amido alkylnaphthols using nano-magnetic particles and surfactants

we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.

Applying hexagonal nanostructured zeolite particles for acetone removal.

This study examines the performance of a new adsorbent, hexagonal nanostructured zeolite particles (HNZP) for acetone adsorption and compares the results with that of commercial mobil synthetic zeolite-5 (ZSM-5) type zeolite. The HNZP is a pure siliceous adsorbent with different values of pore diameter and surface area being adjustable by the manufacturing condition. The results indicate that a...

Laser removal of particles from solid surfaces

Laser removal of particles from solid surfaces was investigated both theoretically and experimentally. A cleaning model was established for laser-induced removal of particles from solid surfaces by taking Van der Waals force, capillary force and cleaning force into account. Laser cleaning forces are induced by fast thermal expansion of particles and/or solid surfaces irradiated by laser for dry...
