At X NaDS =0.6, two monotonic curves can be distinguished in the Δ H ( W→W+S ) vs. m t trend. Experimental data were fitted through an equation previously reported for additives in pure surfactants derived by assuming the pseudo-phase transition model for the micellization and a mass ...
A kinetic study of the mechanism of the nitrosation of dimethylamine ( DMA ) by propyl nitrite ( Pr ONO) in basic media to yield N-nitrosodimethylamine ( NDMA ) has found the rate equation to bewhere [ DMA ] and [ Pr ONO] are total concentrations. At 298.2 K and I =0.25 M , k ...
The latter finding strongly suggested that the solvent property of the micellar surface of nonionic DDAO is different from that of water and more like that of the Brij micelle surface. Thus the above equation is applicable to the micelle-solubilizate systems....
The corresponding work of adhesion W was calculated using the DMT (Derjaguin, Muller, Toporov) equation. The values of W obtained are small compared to literature data and suggest that only a fraction of the functional groups in the contact area is involved in acid-base or H-bond ...
The nN columns list the calculated increase in moles of N in the particles after exposure to NH3 or DMA calculated from the monitor data (Equation (3)) and AMS data (Equation (4)). The increase in N:C ratio 2 h after the injection of NH3 or DMA is reported as ∆N:C. Adding 2...
