Removal Efficiencies

Inhalable particles suspended in air were an important pollution of atmospheric Environment. Because of very small in size, they were different to be captured by conventional filter. Chemical active agent, surfactant and flocculate, were introduced into chamber and encouraged the agglomeration of inhalable particles. Nonionic surfactant could reduce more than 30% of particles, while ionic surfactant could lead to the decrement of 23-26%. The particle removal efficiencies were only 15-18% in the presence of polymer flocculate and slightly above that of water. The larger droplet of spray favored the agglomeration of inhalable particles. Increasing the surfactant concentration resulted in the higher removal of inhalable particle.

Optical reflectometry is applied as a tool for studying single and simultaneous adsorption of a carbohydrate, a nonionic surfactant, and a protein, For the nonionic surfactant poly(ethylene oxide) alkyl ether on a silica surface the adsorption process is fast and reversible, and the maximum adsorbed amount was 2.45 mg•m-2. Also, the effect of pH on the adsorption of chitosan on silica, and its interaction with C12EO5have been studied. The maximum adsorbed amount was obtained for pH ≥6.8 (0.80 mg•m-2). Changes in surface functionality upon adsorbing C12EO5on a chitosan layer and the protein, bovine serum albumin, are reported. The results are discussed in terms of adsorption kinetics, adsorbed mass plateau values, and reversibility of layer formation.
