Heavy solvents absorption appears to be very attractive in recovering of volatile organic compounds (VOCs) from industrial tail gas. Their high viscosities make good dispersion required but difficult to reduce mass transfer resistance. Microencapsulation techniques provide a candidate solution. In this paper, vapor pressures for toluene+poly(dimethylsiloxane) (PDMS) mixtures were measured at ...

The basic technology behind PRP is thousands of microcapsules, tiny balls of beeswax with hollow centers. Water cannot penetrate the microcapsule s cell, but oil is absorbed right into the beeswax spheres as they float on the water s surface. This way, th...

In the present paper, fluorescein isothiocyanate was chosen as a fluorescence probe to mark casein protein in alkaline conditions. The interaction of the casein protein marked or not marked and fluorescein isothiocyanate was preliminarily discussed by the spectrum changes of UV-absorption and fluorescence spectrometry. Fluorescent marker was separated from SephadexG-50 chromatography ...

The possibility and effectiveness of microencapsulation of okadaic acid (OA) in gelatin-acacia microcapsules has been studied. The encapsulation efficiency was higher than 33%. The microcapsules were shown to be very stable, not leaching more than 9% of the encapsulated OA in a 20-h period. OA from the microcapsules was ...
